A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
The ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with grinding media (balls), which can be made of steel (chrome steel), stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber.
When the mill rotates, the grinding media (balls) are lifted to a certain height and then cascade down, impacting the material to be ground. The grinding action is a combination of impact, attrition, and abrasion. The material is crushed by the impact of the falling balls and the friction between the balls and the mill's inner surface. The rotation speed of the mill is critical: if it is too low, the balls will not cascade effectively, and if it is too high, the balls will be pinned to the inner wall by centrifugal force, reducing grinding efficiency.
The size of the grinding media and the material to be ground, along with the rotation speed, determine the fineness of the final product. Ball mills are widely used in industrial applications due to their ability to produce a fine and homogeneous product.
GCH/S Series Single CylinderHydraulic Cone Crusher
The GCH/S Series Single Cylinder Hydraulic Cone Crusher operates based on a combination of mechanical and hydraulic principles to achieve efficient and reliable crushing of various materials.
Power Transmission
The crusher is driven by an electric motor. The motor's power is transferred to the pulley, which is connected to the main shaft through a V - belt or a coupling. As the pulley rotates, it causes the main shaft to spin. The main shaft is equipped with an eccentric sleeve. When the main shaft rotates, the eccentric sleeve also rotates around the main shaft, creating an eccentric motion.
Crushing Chamber and Material Crushing
The crushing chamber of the GCH/S Series Single Cylinder Hydraulic Cone Crusher is formed by the fixed cone (outer cone) and the movable cone (inner cone). The fixed cone is a stationary part of the crusher frame, while the movable cone is connected to the main shaft and is affected by the eccentric motion of the eccentric sleeve.
When the eccentric sleeve rotates, the movable cone performs a gyratory motion around the central axis of the crusher. This means that the movable cone gets closer to and farther away from the fixed cone at different positions around the crushing chamber.
Materials are fed into the crusher from the top - side feed opening and enter the crushing chamber. As the movable cone gyrates, at the positions where the movable cone approaches the fixed cone, the materials are subjected to a combination of compressive, shearing, and bending forces. These forces break the materials into smaller pieces. The unique design of the crushing chamber and the gyratory motion of the movable cone ensure that the materials are crushed multiple times as they pass through the chamber, achieving a high - efficiency crushing process.
Hydraulic System and Its Functions
The single - cylinder hydraulic system is a key feature of this crusher. The hydraulic cylinder is located at the bottom of the crusher. It serves several important functions:
Discharge Opening Adjustment
The hydraulic cylinder can adjust the position of the movable cone. By increasing or decreasing the hydraulic pressure in the cylinder, the height of the movable cone can be changed. This directly affects the size of the discharge opening between the fixed cone and the movable cone. Operators can easily adjust the discharge opening size according to the required particle size of the final product, which provides great flexibility in the production process.
Overload Protection
In case of an overload situation, such as when a large un - crushable object (like a piece of iron) enters the crushing chamber, the hydraulic system can quickly release the pressure. This allows the movable cone to move downward, increasing the discharge opening and allowing the un - crushable object to pass through the crusher without causing damage to the machine. After the overload situation is resolved, the hydraulic system can restore the normal position of the movable cone, and the crusher can resume normal operation.
Cavity Clearing
If the crushing chamber becomes blocked with materials, the hydraulic system can be used to lift the movable cone, creating a larger space in the chamber. This makes it easier to clear the blocked materials, reducing downtime and improving the overall efficiency of the crusher.
Discharging Process
After the materials are crushed in the crushing chamber, they fall downwards under the influence of gravity. The crushed materials are then discharged from the bottom of the crusher through the adjustable discharge opening. The size of the discharge opening, which is controlled by the hydraulic system, determines the particle size of the discharged materials, ensuring that the final product meets the specific requirements of different applications.
In summary, the GCH/S Series Single Cylinder Hydraulic Cone Crusher uses a combination of mechanical power transmission, gyratory motion of the movable cone, and a sophisticated single - cylinder hydraulic system to achieve efficient material crushing, precise particle size control, and reliable operation with effective overload protection and cavity - clearing capabilities.
GHP Series Multi-CylinderHigh Efficiency Cone Crusher
Working Principle of GHP Series Multi - Cylinder High Efficiency Cone Crusher
The GHP series multi - cylinder high - efficiency cone crusher operates on a well - engineered principle that combines mechanical, hydraulic, and lamination crushing concepts to achieve efficient and high - quality material crushing.
Power Transmission and Eccentric Movement
The crusher is powered by an electric motor. The motor drives the pulley, which is connected to the transmission shaft. As the pulley rotates, it transfers the power to the transmission shaft, causing it to spin. The transmission shaft is equipped with a bevel gear that meshes with another bevel gear on the eccentric sleeve. This gear - meshing mechanism enables the rotation of the eccentric sleeve.
The main shaft of the crusher is fixed, and the eccentric sleeve rotates around it. When the eccentric sleeve rotates, it creates an eccentric movement. The cone part, which is connected to the main shaft, is affected by this eccentric movement. As a result, the cone part performs a gyratory motion around the central axis of the crusher.
Crushing Process
The crushing chamber of the GHP series cone crusher is formed by the fixed cone (outer cone) and the movable cone (inner cone). The fixed cone is a stationary part of the crusher frame, while the movable cone gyrates within the fixed cone due to the eccentric movement.
When materials are fed into the crusher from the top - side feed opening, they enter the crushing chamber. As the movable cone gyrates, it gets closer to and farther away from the fixed cone at different positions around the crushing chamber. At the places where the movable cone approaches the fixed cone, the materials are subjected to a combination of impact, extrusion, grinding, and rubbing forces.
The lamination crushing principle plays a crucial role in this process. The materials are not only crushed by the direct contact between the cones but also by the interaction between the particles themselves. The particles are forced to break along their natural weak points under the high - pressure environment created by the moving cones, resulting in a more efficient and uniform crushing effect.
Discharging Process
As the movable cone moves away from the fixed cone, the crushed materials fall downwards under the influence of gravity. The crushed materials are then discharged from the bottom of the crusher. The size of the discharge opening can be adjusted according to the specific requirements of the production process. This is achieved through a hydraulic adjustment system.
Hydraulic System Functions
The hydraulic system in the GHP series cone crusher serves multiple important functions. Firstly, it is used for adjusting the size of the discharge opening. By controlling the hydraulic pressure, the position of the movable cone can be precisely adjusted, thereby changing the gap between the fixed cone and the movable cone and controlling the particle size of the discharged materials.
Secondly, the hydraulic system provides an effective overload protection mechanism. In case of an iron - passing fault or a blockage in the crushing chamber, the hydraulic system can release the pressure, allowing the movable cone to move back slightly. This helps to prevent damage to the crusher components and ensures the safe and stable operation of the equipment.
In summary, the GHP series multi - cylinder high - efficiency cone crusher uses a combination of power transmission, eccentric movement, lamination crushing, and a well - designed hydraulic system to achieve efficient material crushing, precise particle size control, and reliable equipment operation.
The Symons cone crusher operates based on a well - defined mechanical principle to efficiently crush materials.
The power source of the Symons cone crusher is an electric motor. The motor drives the V - belt, which in turn rotates the belt wheel. The belt wheel is connected to the transmission shaft, and as the belt wheel spins, it causes the transmission shaft to rotate. The transmission shaft is equipped with a small cone cogwheel that meshes with a large cone cogwheel. This gear - meshing mechanism transfers the rotational motion from the transmission shaft to the large cone cogwheel, which is attached to the eccentric sleeve. As a result, the eccentric sleeve starts to rotate.
The main shaft of the crusher is inserted into the eccentric sleeve. When the eccentric sleeve rotates, it exerts an eccentric force on the main shaft, causing the main shaft to swing. The main shaft is connected to the movable cone. So, the swinging motion of the main shaft makes the movable cone perform a gyratory movement around the perpendicular of the cone crusher.
The crushing chamber of the Symons cone crusher is formed by the fixed cone and the movable cone. The fixed cone is stationary and is an integral part of the crusher frame, while the movable cone moves in a gyratory manner. As the movable cone gyrates, it gets closer to and farther away from the fixed cone at different positions around the crushing chamber.
When materials are fed into the crusher from the top - side feed opening, they enter the crushing chamber. At the places where the movable cone approaches the fixed cone, the materials are subjected to a combination of compressive, bending, and shearing forces. These forces break the materials into smaller pieces. As the movable cone moves away from the fixed cone, the crushed materials fall downwards under the influence of gravity and are discharged from the bottom of the crusher. This continuous gyratory motion of the movable cone ensures that the crushing process occurs continuously, with new materials being fed in and crushed materials being discharged, achieving a high - efficiency crushing operation.
In summary, the Symons cone crusher uses the gyratory motion of the movable cone relative to the fixed cone, driven by a complex system of belts, gears, and an eccentric sleeve, to crush materials effectively and continuously.
Composite High-Efficiency Cone Crusher
The Symmons Cone Crusher is a well - known and highly efficient crushing equipment with a long - standing reputation in the industry.
1. History and Origin
It has a rich history. The spring - loaded cone crusher, which is also known as the Symmons cone crusher, was designed by two brothers in Milwaukee, the United States. Since its invention, it has undergone continuous improvements over about a hundred years, and its basic structure has become quite mature. Nordberg has produced more than 17,000 Symmons cone crusher units throughout the world, accounting for about 70 percent of the world's total existing cone crusher units.
2. Working Principle
The working principle of the Symmons Cone Crusher is based on the rotation of an eccentric sleeve. The crusher motor powers a drive shaft and bevel gear, which in turn drives the eccentric sleeve to rotate. The spindle is inserted into the tapered hole of the eccentric sleeve, and the moving cone is solidly supported on the spindle and spherical bearings. As the eccentric sleeve rotates, the center of the moving cone makes a conical movement around the centerline of the crusher. When the moving cone approaches the fixed cone, the ore is squeezed and crushed. When it moves away, the crushed ore is pushed out from the bottom of the two cones by gravity.
3. Advantages
High Output: Compared with many other types of crushers, the Symmons Cone Crusher can achieve a relatively high production volume, which is suitable for large - scale industrial production.

3. Safety and Sealing Systems
The spring safety system of the crusher acts as an overloading protection system. It allows metal to pass through the crushing chamber without causing damage to the crusher. The safety system uses dry oil and water as two kinds of sealed formations to separate plaster powder and engine oil, ensuring reliable performance and preventing dust and other impurities from entering the internal components.
4. Types and Their Applications
There are different types of spring cone crushers, including the standard type (PYB), the medium type (PYZ), and the short - head type (PYD). The standard type is applied to secondary crushing, while the medium and short - head types are used for fine crushing, meeting different levels of crushing fineness requirements.
5. Working Principle
When the crusher is working, the motor drives the eccentric bearing bushing via spring coupling, transmission shaft, and a couple of cone gear wheels. The crushing cone axis is forced to swing by the eccentric bearing bushing, making the mantle close to and far away from the bowl liner periodically. As a result, the raw materials are pressed, impacted, and finally crushed in the crushing cavity.
Jaw Crusher Overview
The jaw crusher, also known as the "tiger's mouth", is a widely - used primary crushing equipment in the mining, construction, and other industries. It is designed to break large rocks and ores into smaller pieces for further processing.
Working Principle
The working part of a jaw crusher consists of two jaws: a fixed jaw and a movable jaw. The fixed jaw is vertically (or slightly outward - inclined at the top) fixed on the front wall of the machine body, while the movable jaw is inclined and forms a crushing chamber with the fixed jaw, which is wider at the top and narrower at the bottom. The movable jaw makes periodic reciprocating movements towards the fixed jaw. When the two jaws separate, materials enter the crushing chamber; when they get closer, the materials between the two jaws are crushed by extrusion, bending, and splitting forces.

Capacity
The processing capacity of jaw crushers varies depending on the model and specifications, generally ranging from 50 to 1500 tons per hour. Different models can be selected according to specific production needs.
In summary, the jaw crusher is a powerful and efficient crushing equipment that plays a crucial role in the industrial production process.
The impact crusher, also known as the impact breaker, is a highly efficient crushing machine widely used in various industries for processing materials.
Working Principle
It operates based on the principle of impact crushing. The high - speed rotating rotor throws the incoming materials against the impact plates installed in the crushing chamber. The materials are crushed by the impact force generated during this process. After the initial impact, the broken materials rebound and are further crushed by subsequent impacts, achieving multiple - stage crushing within the chamber.
Features
High Crushing Ratio: It can achieve a large crushing ratio, sometimes up to 40. This means that it can significantly reduce the size of the input materials in a single pass, which simplifies the crushing process and may turn a three - stage crushing process into a two - stage or even a single - stage one, thus reducing equipment costs in a processing plant.
Good Particle Shape: The crushed products have a cubic shape, which is highly desirable in many applications such as the production of high - quality aggregates for construction. The impact - based crushing method ensures that the materials are broken along their natural weak points, resulting in well - shaped particles.
Efficient and Energy - Saving: With optimized design, it can operate at relatively low rotational speeds while still maintaining high production capacity. This not only reduces energy consumption but also minimizes wear and tear on the components, leading to longer service life and lower maintenance costs.
Adjustable Discharge Size: The gap between the impact plate and the hammer can be easily adjusted, allowing for precise control of the discharge particle size according to the specific requirements of the production process.
Versatile Application: It can handle a wide range of materials, including limestone, feldspar, calcite, talc, barite, dolomite, kaolin, gypsum, graphite, and many others. It is suitable for industries such as metallurgy, chemical, building materials, and hydropower, especially for processing materials that require frequent relocation, like those in highway, railway, and hydropower projects.
Applications
Impact crushers are commonly used in the production of aggregates for construction, the processing of minerals in mining operations, and the recycling of construction waste. In the construction industry, they are used to produce high - quality crushed stones for concrete production, road base construction, and other infrastructure projects. In the mining sector, they help in the initial processing of ores to prepare them for further refining. In waste recycling, they can break down large pieces of construction waste into reusable aggregates.
In conclusion, the impact crusher is a reliable and efficient piece of equipment that offers significant advantages in terms of crushing performance, product quality, and cost - effectiveness, making it an essential tool in many industrial processes.
Working Principle of Double (Pair) Roller Crusher
The double (pair) roller crusher is a type of roll - type crushing machine that operates based on a relatively straightforward yet effective principle to crush various materials.
1. Power Transmission
The crusher is typically powered by an electric motor. The motor's power is transferred to the pulleys through a V - belt or a coupling. These pulleys are connected to the shafts of the two rollers. As the motor rotates, it drives the pulleys, which in turn cause the two rollers to rotate. The two rollers usually rotate in opposite directions, which is crucial for the crushing process.
2. Material Feeding
Materials to be crushed are fed into the crusher from the top - side feed hopper. The feed hopper is designed to ensure a steady and even flow of materials into the space between the two rollers. The size of the feed materials should generally be within the specified feed particle size range of the crusher, which is usually ≤150 mm for many double roller crushers.
3. Crushing Process
Extrusion and Shear Forces
Once the materials enter the space between the two rotating rollers, they are subjected to a combination of extrusion and shear forces. The two rollers are fixed with high - strength wear - resistant alloy rolls. Their relative rotation generates high extrusion pressure. As the materials are squeezed between the rollers, the extrusion force breaks the materials into smaller pieces. At the same time, the difference in the rotational speed and the surface characteristics of the rollers also create shear forces. These shear forces further contribute to the crushing of the materials by cutting and tearing them apart.
Tooth - Shape Adaptability
In some double roller crushers, the tooth shape, size, and arrangement on the rollers can be adjusted according to the properties of the materials. This adaptability allows the crusher to better handle different types of materials, whether they are hard or soft ores. The teeth on the rollers can grip the materials more effectively, enhancing the crushing efficiency.
4. Discharge and Size Control
Discharged Materials
After being crushed, the materials are pushed rotatorily by the rollers and fall out from the bottom of the crusher. The crushed materials are then transported away by the subsequent conveying equipment for further processing or use.
Size Adjustment
The spacing between the two rollers can be adjusted to control the size of the discharged materials. There are usually wedge or gasket adjusting devices arranged between the two rollers. For example, in a wedge - type adjusting device, there is an adjusting bolt at the top. When the adjusting bolt is turned, it can pull up the wedge, which then moves the movable roller away from or towards the fixed roller. By changing the distance between the rollers, the desired particle size of the discharged materials can be achieved.
5. Self - Protection
Some double roller crushers are equipped with a self - protection function. When hard materials such as metals enter the crushing cavity, the crusher components can self - protect to avoid damage. For instance, the rollers may be able to withstand a certain impact force or the crusher may have a mechanism to detect the abnormal situation and stop the operation to prevent serious damage.
In summary, the double (pair) roller crusher uses power transmission to drive the rotation of two opposite - rotating rollers, applies extrusion and shear forces to crush the materials fed between the rollers, and can adjust the discharge particle size through the roller spacing adjustment mechanism, all while having certain self - protection capabilities.
