Jaw crushers are usually used for the primary crushing stage in production lines, and their output directly affects the capacity of the entire production line. Meanwhile, we can reduce equipment idle by increasing output per unit time, thus reducing energy consumption and labor costs, finally improving the overall efficiency. Today, we are glad to share with you a few tips for increasing capacity for Jaw crusher.

 

1. Optimize the feed size, STUCK NO MORE!

• Material selection: 

  Choose dry and low mud materials to reduce adhesion and clogging in the crushing process and improve crushing efficiency.

• Feed size:

  Control the feed size less than 85% short side of the crusher inlet size, or oversize material will easy to be stuck at the opening of jaw crusher.

2. Control the feed rate, avoid overfeed clogging

• Constant right feeding rate:Jaw crushers are intermittent working equipment. Underfeed or overfeed both affect the final capacity. Underfeed results in a light load. Overfeed leads to Material accumulation, can’t be crushed in time.

      Therefore, we should strictly control the feeding rate,at the same time, keep a constant feeding rate by adjusting the amplitude of the feeder  (within the feeder amplitude range) according to the output demand of the production line. Normally, when the feeding rate is up to 2/3 of the crushing chamber,the efficiency is the highest.

      Meanwhile,we should also avoid the material directly impact the moving jaw when feeding,and prevent the head of the moving jaw when  feeding, and prevent the head of the moving jaw to be damaged. Additionally, adjusting feed angle ensure feeding smooth.

3. Adjust equipment properly, improve processing capacity

• Adjustment of CSS and the angle between the movable jaw plate and the fixed jaw:Due to CSS of jaw crusher determines the production capacity,we should make appropriate adjustments for CSS according to the demand size for two-stage crushing. The angle (between the moving jaw plate and the fixed jaw plate) is generally within the range of 17-26 °. Appropriately increasing the CSS size, reducing the angle and crushing rate can improve production efficiency.
• Adjustment of eccentric shaft speed: 

  Increasing the eccentric shaft speed appropriately is good for improving material crushing efficiency. But it should be noted that excessive speed may make materials not be discharged in time, causing material blockage and reducing production capacity.

  

4. Regular maintenance equipment

• Jaw plate adjustment and replacement:Regularly maintain and inspect the equipment to ensure that it is in good condition. Regularly check the wear status of the jaw plate and take some measures according to the wear situation, such as turning around, exchanging or replacing the jaw plate, which helps to maintain the crushing efficiency of the crusher.
• Lubrication and maintenance:

  High quality lubrication is the key to ensure the performance and service life of bearings. In daily equipment operation, the bearings of jaw crushers should be regularly lubricated and maintained to ensure their normal operation.

Take care of your  jaw crushers anytime, anywhere. For more information, you can also contact your local dealer or Borgers service team.

In the world of machining, lathes, and turning centers play a vital role in shaping metal and other materials into precision parts. While both machines perform similar functions—rotating a workpiece to perform cutting, drilling, or milling tasks—their capabilities, complexity, and applications can differ significantly.

As advancements in CNC (Computer Numerical Control) technology evolve, manufacturers are faced with choosing between the simplicity of a traditional lathe and the advanced automation of a turning center.

This article provides a comparison of turning centers and lathes, outlining their features, functionalities, and ideal use cases. By the end, you’ll have a clear understanding of which machine suits your specific manufacturing needs.

So, let’s begin!

What is a Lathe?

A lathe is one of the oldest and most versatile machines used in manufacturing. At its core, a lathe rotates a workpiece on its axis while various tools are applied to cut, shape, or drill the material. Over centuries, the lathe has evolved from rudimentary designs to highly sophisticated machines that play a pivotal role in modern industry.

Today, lathes can range from traditional manual models to advanced CNC (Computer Numerical Control) machines capable of producing intricate and precise parts.

 

Traditional vs. Modern Lathes

Traditional lathes, also known as manual lathes, require the operator to manually adjust the cutting tools and guide the workpiece to achieve the desired shape. These machines are typically used for simple operations like turning cylindrical objects, threading, and drilling. While still widely used, they require skilled operators and are best suited for low-volume production or smaller projects.

Modern lathes, particularly CNC lathe machines, are highly automated and can handle more complex tasks with little human intervention. These machines are controlled by pre-programmed software that allows for precise, repeatable operations. CNC lathes are commonly used in high-volume production environments where accuracy and efficiency are critical.

 

Types of Lathes

1. Manual Lathes: These machines rely on the operator’s skill to manually adjust the cutting tool, speed, and feed rate. They are ideal for smaller, simpler projects but require greater hands-on expertise.

2. CNC Lathes: CNC lathes are automated and controlled by computer programs, enabling highly accurate and repeatable cuts. They are often used for large-scale production or complex components that require precision beyond manual capabilities.

 

Core Components

Every lathe, whether manual or CNC, shares several essential components:

● Headstock: The part of the lathe that holds the motor and the drive mechanism. It houses the spindle, which rotates the workpiece.

● Spindle: Located within the headstock, the spindle holds and rotates the workpiece, ensuring it is aligned with the cutting tool.

● Tool Post: This is where the cutting tools are mounted. The tool post can be adjusted to move the cutting tool toward or away from the workpiece.

● Chuck: The chuck is the gripping device that holds the workpiece securely in place while it rotates.

 

What is a Turning Center?

A turning center is an advanced machine tool designed to perform a wide variety of tasks beyond simple turning operations. While similar to a lathe in its basic function of rotating a workpiece to perform cutting, turning centers are equipped with enhanced automation, multi-axis capabilities, and additional features that allow them to handle more complex machining tasks.

These machines are highly automated and can complete multiple processes—such as turning, milling, drilling, and tapping—within a single setup, reducing production time and increasing efficiency.

Key features of a turning center include CNC control, live tooling, automatic tool changers, and multi-axis movement. The ability to perform various tasks in one machine means turning centers are ideal for high-volume production environments where efficiency and precision are essential.

Modern Developments and Automation

Modern turning centers have significantly evolved from traditional lathes due to advancements in CNC technology and automation. With computer-aided design (CAD) and computer-aided manufacturing (CAM) integration, turning centers can execute complex machining tasks with minimal operator input.

Automation has enabled turning centers to process multiple parts in a single run, drastically reducing setup time and improving production speed. The inclusion of robotic arms for material loading and unloading further increases their productivity.

Additionally, modern turning centers often feature live tooling—tools that are powered and capable of performing milling, drilling, or other operations while the workpiece is stationary. This allows turning centers to produce more intricate and varied parts without the need to transfer the workpiece to another machine.

 

Differences from Traditional CNC Lathes

While both turning centers and CNC lathes are used for machining cylindrical parts, turning centers offer more advanced technology and capabilities. A traditional CNC lathe is designed primarily for turning operations, which involves rotating the workpiece and cutting material to create cylindrical shapes.

In contrast, turning centers are multi-tasking machines that can perform milling, drilling, boring, and even threading operations alongside turning.

The key differences include:

● Multi-Axis Capabilities: CNC lathes typically operate on two axes (X and Z), whereas turning centers can operate on multiple axes, including Y and C axes, allowing for more complex geometries.

● Live Tooling: Turning centers often come with live tooling that allows them to perform additional functions like milling, drilling, and tapping without requiring separate machines.

● Automatic Tool Changers: Unlike CNC lathes, which may require manual tool changes, turning centers use automatic tool changers (ATC) to switch between tools during operation, enabling continuous, uninterrupted machining.

These advancements make turning centers more suitable for complex parts and high-volume production where speed, accuracy, and flexibility are critical.

 

Types of Turning Centers

Turning centers come in various configurations to suit different machining needs. The two primary types are:

1. Horizontal Turning Centers: In these machines, the spindle is oriented horizontally. They are the most common type and are used for tasks where gravity assists in removing chips from the work area. Horizontal turning centers are ideal for longer workpieces and are widely used in industries like automotive and aerospace.

2. Vertical Turning Centers: In vertical turning centers, the spindle is positioned vertically, and the workpiece is mounted on a horizontal table. These machines are often used for larger, heavier parts that are difficult to hold in a horizontal orientation. Vertical turning centers are typically used in industries where large diameters and heavy parts, such as gear manufacturing, are common.

Within these categories, turning centers can also be classified based on the number of turrets they have:

● Single-Turret Turning Centers: These machines have one tool turret, which limits the number of tools available at any given time. However, they are still capable of performing multi-tasking operations due to live tooling.

● Multi-Turret Turning Centers: Machines with two or more turrets allow for even greater versatility. They can use multiple tools simultaneously, increasing machining efficiency by reducing tool change times and allowing for parallel operations on the same workpiece.

 

Capabilities and Functions

Turning centers are versatile machines capable of performing a wide range of tasks beyond basic turning. Their multi-tasking abilities set them apart from traditional lathes. Some of their key functions include:

● Turning: Like a lathe, turning centers perform traditional turning operations, where a rotating workpiece is shaped by cutting tools.

● Milling: Equipped with live tooling, turning centers can perform milling operations, which involve removing material from the workpiece using rotating cutting tools, often to create flat surfaces or intricate shapes.

● Drilling and Tapping: Turning centers can drill holes into the workpiece, as well as tap threads, eliminating the need for separate drilling or tapping machines.

● Boring and Grooving: Precision internal machining such as boring (enlarging holes) and grooving (cutting channels) can be performed without needing to transfer the workpiece to another machine.

● Threading: Turning centers can also cut threads for bolts or screws, combining multiple operations into one seamless process.

 

Key Differences Between a Lathe and a Turning Center

A transformer is a device used for converting electrical energy, which can increase or decrease the voltage of alternating current to meet the needs of different circuits. The working principle of transformers is based on the principle of electromagnetic induction. Below, we will provide a detailed introduction to the production process and working principle of transformers.

• The production process of transformers

The production process of transformers mainly includes the following steps:

1. Preparation materials: The main materials for transformers include iron cores, coils, and insulation materials. Prepare corresponding materials according to the specifications and design requirements of the transformer.

2. Coil winding: According to the design requirements, the wire is wound on the iron core to form primary and secondary coils.

3. Assembly: Assemble the wound coil, iron core, and other components together to form a complete transformer.

4. Testing: Test the assembled transformer to check whether its electrical and mechanical performance meets the design requirements.

5. Packaging: Qualified transformers are packaged for delivery and use after testing.

• Working principle of transformers

The working principle of a transformer is based on the principle of electromagnetic induction, as follows:

When alternating current passes through the primary coil, an alternating magnetic field is generated, which passes through the iron core and generates induced electromotive force in the secondary coil.

Due to the electromagnetic coupling between the secondary coil and the primary coil, the induced electromotive force in the secondary coil is proportional to the current in the primary coil.

Therefore, by changing the current in the primary coil (i.e. changing the applied voltage), the induced electromotive force in the secondary coil can be changed, thereby achieving an increase or decrease in voltage.

4. In addition, according to the law of electromagnetic induction, the induced electromotive force is proportional to the number of turns in the coil. Therefore, by changing the number of turns in the coil, the voltage can also be increased or decreased.

In short, a transformer is an electrical energy conversion device based on the principle of electromagnetic induction, which can increase or decrease the AC voltage by changing the number of coil turns or the applied voltage. The production process of transformers includes steps such as preparing materials, winding coils, assembling, testing, and packaging. Understanding the production process and working principle of transformers helps to better understand and apply this important electrical equipment.

Drones, once only used in the military field, are now redefining precision agriculture. Nowadays, the number of farmers using drones on their own farms is steadily increasing. Various drones provide them with low-cost aerial camera platforms. In this way, farmers can monitor crops in an economically effective way. In use, drones are used to capture crop images, which are later processed by specialized software to obtain reflectance images of farm crops.

Currently, there are more and more extreme weather conditions. Accompanying the growth of the world population is a huge increase in the consumption of agricultural products. Considering these circumstances, more and more farmers are expected to use drone technology. The use of drones in the agricultural sector has brought many benefits. But like any other technology, drones also have their advantages and disadvantages, which intentional buyers should be aware of before making a purchase.

Advantages of agricultural drones

1. Agricultural analysis

Drones can be used for soil and farmland analysis. With the help of drones, accurate 3D maps can be generated for analysis of soil properties, soil moisture content, and soil erosion, which are crucial for precision seeding in planting modes. Even after planting, the above information on farmland irrigation and nitrogen level management is very helpful.

2. Planting

At present, although drone planting is not yet common, some manufacturers have proposed system solutions that hope to shoot pods containing seeds and plant nutrients into prepared farmland soil, which will greatly reduce planting costs.

3 Monitoring

One of the biggest obstacles in agricultural production is the inability to efficiently monitor crops in large areas of farmland. The emergence of unpredictable weather patterns leads to increased risks and maintenance costs, making this obstacle even worse. Drones can be used to create time series animations that display accurate crop growth conditions, allowing for better management of crops by showcasing their precise growth processes.

4. Agricultural spraying

By using ultrasonic echoes and lasers, drones can adjust their flight altitude according to changes in terrain and geography. The ability of drones to scan and adjust their distance from the ground enables them to spray the correct amount of medication in real-time and evenly. This improves efficiency and minimizes the amount of groundwater infiltration. The use of drones for spraying has been proven to be faster than other traditional methods.

5. Irrigation

Drones equipped with thermal and hyperspectral sensors can identify parts of the field that have become dry, which can help people irrigate accurately and timely at specific locations.

6. Health assessment

Some drones can scan crops through visible light and near-infrared light, and the light processing equipment they carry can recognize the amount of green light and near-infrared light reflected by plants. These data are then used to develop multispectral images that describe the health status of plants. These images can be used to track the health status of crops and provide recommendations for remedial measures upon detecting any diseases.

7. Easy to deploy

Unlike traditional aircraft, drones are easier to deploy and have lower costs.

Disadvantages of agricultural drones

1. Flight time and range

There are also some issues with agricultural drones, with most drones having a short flight time, typically between 20 minutes and 1 hour. This flight time limits the area that each flight battery can cover. And the flight range also limits the radius within which a single drone can fly. Drones with longer flight times and larger flight radii are expensive.

2. Initial purchase cost

Drones that can be used in the agricultural field are quite expensive. The current cost of fixed wing drones is as high as $25000. There are also some drones whose high prices include hardware, software, tools, and imaging sensors.

Purchasing drones without relevant equipment is cheap, but the high cost of cameras and processing software that meet the requirements makes the difference between the two not significant. However, the cost of purchasing a complete set of agricultural drone equipment in the short term is high, but it is worth it in the long run.

3. Federal laws

According to federal law in the United States, drones used for agricultural purposes are considered commercial, which means farmers need to receive FAA operator training and obtain remote driving certificates or hire operators with such qualifications. The FAA also requires drones to fly at an altitude not exceeding 400 feet.

Interference within the airspace of 4

Agricultural drones and manned aircraft share the same airspace, making them susceptible to interference with each other. Therefore, it is recommended to submit a flight plan to the local airport or FAA before using the drone.

5. Highly affected by weather conditions

Unlike traditional aircraft, drones are more susceptible to the influence of climate conditions. If it is windy or rainy outdoors, the drone will not be able to fly.

6. Knowledge and skills

The images obtained by drones require professionals to convert them into useful information, which means that ordinary farmers may need to attend training or have to hire professional analysis software personnel to assist with image processing.

Drone technology is constantly improving every day, and as more and more manufacturers enter the industry, the cost of drones and related equipment will decrease. It is expected that limitations such as flight time and range will be addressed through technological improvements. This will enable farmers to gain more benefits from the use of drones.

In today's rapidly developing electric vehicle market, choosing the right charging station has become one of the important issues faced by car owners. What is the difference between DC charging stations and AC charging station areas? What aspects are different? What are the applicable scenarios for each? How to choose different scenarios? This article will provide you with a detailed explanation.

Working principle of DC charging station and AC charging station

The charging process of electric vehicles requires the conversion of alternating current (AC) from an external power source into direct current (DC) stored in the battery. The AC charging station hands over this conversion process to the car charger, which converts the external AC power into DC power for storage. The DC charging station completes the conversion process from AC to DC inside the charging station, directly supplying DC power to the electric vehicle battery.

Advantages and Applications of Communication Charging Stations

The AC charging station (commonly known as "slow charging") charges the battery of an electric vehicle through a car charger, and the charging process requires the car charger to convert AC power into DC power. This method of charging is relatively slow, but it causes less battery damage.

1. Lower cost: Due to the simple converter of AC charging stations and the fact that the main power conversion is completed inside the car charger, the cost of AC charging stations is lower compared to DC charging stations.

2. Easy installation and maintenance: AC charging stations have a small volume, flexible installation, and relatively low requirements for ground bearing capacity, making them easy to install and use in personal residences, commercial buildings, and other places.

3. Wide applicability: Almost all electric vehicles support AC charging, making AC charging stations more widely applicable.

However, the charging efficiency of communication charging stations is relatively low, usually taking several hours to complete the charging process, making them more suitable for situations where people stay at home or work for a long time.

Advantages and Applications of DC Charging Stations

Flow charging stations (also known as "fast charging stations") directly convert alternating current into direct current to quickly charge the batteries of electric vehicles with high power. This method can bypass the limitations of car chargers and directly charge the battery, resulting in a faster charging speed.

1. Fast charging speed: The most significant advantage is the fast charging speed. For consumers in urgent need of quick power replenishment, DC charging stations can charge electric vehicles to around 80% of their capacity within 30 minutes, greatly improving charging efficiency.

2. High efficiency conversion: Due to the fact that the power conversion process is completed inside the charging station, energy transmission losses are reduced and charging efficiency is improved.

3. High degree of intelligence: DC charging stations are generally equipped with more advanced control systems and user interfaces, which can provide more charging management and payment functions.

The main disadvantage of DC charging stations is their high cost and relatively strict installation and maintenance requirements. Therefore, they are more commonly installed in public charging stations and fast charging networks.

Comparison of Core Differences between DC Charging Stations and AC Charging Stations

1. Charging speed

DC charging station: Due to its high charging power, usually above 60kW, there are other specifications such as 30kW, 120kW, 160kW, 360kW, 380kW, etc. Supercharging stations can even reach 800kW, so the charging speed is faster. In an ideal situation, the battery can be fully charged within 20-150 minutes;

AC charging station: The charging power of AC charging stations is generally low, usually around 7kW, and there are other specifications such as 3.5kW and 11KW, so the charging time is longer, usually taking 8-15 hours to fully charge the battery;

2. Charging pile cost

DC charging station: The manufacturing and installation costs of DC charging stations are relatively high, requiring large volume transformers and AC-DC conversion modules, which are much more expensive than AC charging stations;

Communication charging station: The manufacturing and installation cost of communication charging stations is relatively low, the structure is simple, the volume is small, and it is easy to install and popularize;

3. Volume of charging station

Due to the large number of internal components, the volume of the DC pile is relatively large, and its charging gun head has nine holes;

The modules of the communication station are relatively few and the volume is small, with a 7-hole charging gun head;

4. Impact on batteries

DC charging station: DC charging stations may cause certain damage to the battery during the charging process, as their output current is high and they release more heat during charging. High temperatures may lead to a sudden decrease in battery capacity and damage to the battery cells;

AC charging station: Due to its low charging power and long charging time, AC charging stations do not cause excessive impact on the battery, which is beneficial for extending battery life;

5. Protection level

DC charging station: Generally, DC charging stations are more commonly used in complex outdoor scenarios, facing more complex weather such as rain and snow, with higher protection levels, generally above IP54 protection level.

AC charging station: Generally, DC charging stations are more commonly used in indoor garage scenarios, facing relatively simple environments and requiring lower levels of protection.

6. Adapt to the scene

DC charging station: Due to its fast charging speed, DC charging stations are suitable for installation in charging stations next to highways, taxi and bus stops, and other scenarios that require high charging time.

Communication charging station: Communication charging stations are suitable for installation in residential areas, parking lots, and other places to meet daily charging needs, especially suitable for night charging because users can charge at night and the battery will be fully charged the next day when using the vehicle.

How to choose between DC charging station and AC charging station?

Choosing the appropriate type of charging station should be based on the following considerations:

1. Charging speed requirement: If you often need fast charging, a DC charging station is a more suitable choice. But if most of the time is spent parking at home or work for a long time, then AC charging stations can meet the demand.

2. Installation site: Considering the installation cost and the adaptability of charging piles to the environment, individual residences and small businesses are more suitable for installing AC charging piles.

3. Budget: If the budget is sufficient, it is possible to consider equipping DC charging stations in public places to attract more electric vehicle owners to use them. However, if the budget is limited, AC charging stations are a more economical choice.

Current situation and development trend of charging pile market

The market concentration of DC charging piles is relatively high, with the market share of major operators reaching 85.2%, and the number of public DC piles continues to grow, but the proportion has decreased. Communication charging stations: Due to their low cost and ease of promotion, communication charging stations are commonly built in residential areas, parking lots, and other places.

With the continuous expansion of the electric vehicle market, both DC charging piles and AC charging piles will be more widely used. In the future, with the advancement of technology and the decrease of costs, both will improve in charging speed, intelligence level, cost-effectiveness, and other aspects. At the same time, new charging technologies such as wireless charging will gradually mature, bringing more and more convenient choices for electric vehicle users.

What is the best size to choose for civilian transformers?

When choosing a civilian transformer, the appropriate capacity depends on the specific usage scenario and requirements. ‌

For household appliance transformers, the general recommendation is to choose a transformer that can carry 80% of the rated power of the equipment. This is because inductive loads (such as motors) have a large instantaneous current when starting, so using 70% of the rated power is sufficient. If it is only used for a short period of time, even smaller power can be selected. For example, choosing a 220/110V transformer with a power range of 50-60W can meet the needs of most households, while also providing appropriate power surplus. ‌

For larger civil buildings or residential areas, the selection of transformers needs to consider the reliability of power supply, initial investment costs, and operational economics. When considering transformer capacity, it should be calculated and determined based on actual load. For example, for the calculation of electricity load in residential buildings, the unit index method needs to be combined with coefficients for calculation. For example, a coefficient of 0.6 can be applied to 30 households per unit, a coefficient of 0.5 can be applied to 60 households per building, and a coefficient of 0.4 can be selected for transformers in 240 households. In addition, as mentioned in typical examples, for the case of 900 households, using a three-phase distribution coefficient of 0.26 and a power consumption of 6kW per household, it is appropriate to calculate the transformer capacity with a load of 1404kW. ‌

In summary, when choosing a civilian transformer, the appropriate transformer capacity should be determined based on specific usage scenarios and requirements. For household use, a transformer of 50-60W can be selected; For larger residential areas or civil buildings, it is necessary to calculate the specific electricity load and select the appropriate transformer capacity to ensure the reliability, economy, and environmental friendliness of power supply.

What Is A Transformer?

Power supply design is an unavoidable issue in current hardware product design. In the previous article, we have discussed several types of DCDC converters. Today, we will explore another low loss buck boost scheme: transformers.

A transformer is an electromagnetic component of a circuit used to change the alternating voltage. It can convert one AC voltage into another through electromagnetic conversion while keeping the power basically unchanged.

Application of Transformers

In the power system, transformers are widely used for increasing or decreasing voltage. It can be used for electrical isolation, significantly improving system safety and reducing the risk of electric shock; The use of transformers also achieves grounding system separation, which can effectively suppress common mode noise; Provided DC isolation to protect sensitive circuits; Simultaneously achieving voltage conversion and impedance matching while isolating; Restricting the scope of fault propagation and improving system reliability; Improved electromagnetic compatibility, helping to meet EMC requirements; Support multiple winding applications and adapt to complex system requirements; It can also be used for special applications such as signal coupling, phase adjustment, and harmonic suppression. These advantages make transformers an indispensable key component in fields such as power, industry, healthcare, and communication, providing solid guarantees for the safety, efficiency, and reliability of modern electrical systems and greatly promoting the development of modern power systems.

Working Principle of Transformer

The working principle of transformers is based on the law of electromagnetic induction. Its electromagnetic structure consists of two or more coils wound around the same iron core. In practical structures, there will be insulation materials used between windings and between windings and iron cores, as well as between the casing and cooling system.

When AC current passes through the primary coil, an alternating magnetic field is generated in the iron core. This alternating magnetic field will induce voltage in the secondary coil. By adjusting the turns ratio of the primary and secondary coils, different output voltages can be obtained. Usually, transformers have more than one circuit, for example, single-phase transformers have two circuits, while three-phase transformers have six circuits.

The iron cores and winding materials of different transformers vary greatly. Julin Technology's PowerExpert supports simple and flexible custom transformer construction. Custom transformers can be built using winding, core or non-linear core, and winding binding (K_Magnatic) devices. The ideal magnetic core supports setting magnetic permeability, cross-sectional area and length, while the nonlinear magnetic core supports setting shape parameters, magnetic domain wall bending constant, hysteresis loss coefficient, saturation magnetization intensity and other coefficients. The magnetic core and winding are set to belong to the same transformer through winding binding devices.
