Jaw Crusher working principle:
The structure of jaw crusher mainly consists of frame, eccentric shaft, large pulley, flywheel, moving jaw, side guard, bracket, bracket rear seat, gap screw, return spring, fixed jaw and movable jaw. The brackets also serve as insurance.
The crushing method of the series jaw crusher is a curved extrusion type. The motor drives the belt and the pulley. The eccentric shaft moves the moving jaw up and down. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thus pushing the moving jaw. The plate approaches the fixed slab, and at the same time, the material is crushed, smashed, crushed, etc.; when the moving squat is down, the angle between the toggle plate and the moving raft becomes smaller, and the moving slab leaves under the action of the tie rod and the spring. The boring plate is fixed, and the broken material is discharged from the lower mouth of the crushing chamber at this time, and the crushing and maneuvering of the motor is continuously crushed and discharged as the motor continuously rotates to realize mass production.
Second, the impact crusher
The impact crusher (reverse blow) can process various coarse, medium and fine materials ores, rocks ( granite , limestone , concrete, etc.) with a particle size of not more than 120-500 mm and a compressive strength of not more than 320 MPa. Hydropower, highways, artificial sand and gravel, crushing and other industries. This series of impact crushing structure is unique, equipped with high chrome plate hammer and unique counter-attack lining; suitable for hard rock crushing, high efficiency and energy saving; adjustable grain size, which can simplify the crushing process, and has large crushing ratio and high crushing efficiency. The product has the advantages of cube shape and selective crushing.
Impact crusher working principle:
The impact crusher is a crushing machine that uses impact energy to break up materials. When the machine is working, the rotor rotates at a high speed under the driving of the motor. When the material enters the action area of ​​the hammer, it collides with the hammer on the rotor, and then is thrown to the counter-attack device to break again, and then from the counter-liner. The spring is returned to the action area of ​​the hammer and re-crushed. This process is repeated. The material is broken into the first, second and third, counter-attack chambers from large to small, until the material is crushed to the required particle size and discharged from the discharge port. Adjusting the gap between the counter frame and the rotor can achieve the purpose of changing the material discharge size and material shape.
Third, hammer crusher

(6) Suitable for crushing medium and hard materials.
(7) The product is cubic, with high bulk density and minimal iron contamination.
(8) Impeller self-lining wear is small and easy to maintain.
Five, rotary crusher
The rotary crusher is a large-scale crushing machine that uses crushing motion of the crushing cone in the cone cavity of the casing to produce extrusion, splitting and bending of the material, and coarse crushing of ore or rock of various hardnesses. The upper end of the main shaft equipped with the crushing cone is supported in the bushing in the middle of the crosspiece, and the lower end is placed in the eccentric hole of the bushing. When the sleeve rotates, the crushing cone rotates around the center line of the machine, and its crushing action is continuous, so the working efficiency is higher than that of the jaw crusher. By the early 1970s, large gyratory crushers were able to process 5,000 tons of material per hour, with a maximum feed diameter of up to 2000 mm.
The rotary crusher realizes the adjustment of the discharge opening and the overload insurance in two ways: First, the mechanical method is adopted, and the upper end of the main shaft has an adjusting nut, and the rotating adjusting nut can be lowered or raised, so that the discharge opening is followed. Larger or smaller, when overloaded, the insurance pin on the drive pulley is cut off to achieve insurance; the second is a hydraulic rotary crusher with hydraulic mode, the main shaft is located on the plunger in the hydraulic cylinder, changing the plunger The volume of the hydraulic fluid changes the up and down position of the crushing cone, thereby changing the size of the discharge opening. When overloaded, the downward pressure of the main shaft increases, forcing the hydraulic oil under the plunger to enter the accumulator in the hydraulic transmission system, causing the crushing cone to descend to increase the discharge opening and discharge the non-material entering the crushing chamber. Broken objects (iron, wood, etc.) to achieve insurance.
Six, cone crusher
Cone crusher widely used in mining industry, metallurgical industry, building industry, road construction industry, chemical industry and silicate industry for crushing hard and medium hard rocks and ores, such as iron ore, limestone, copper ore, quartz, Granite, sandstone, etc.
Brief introduction of cone crusher structure and main parameters: cone crusher has the main structure of frame, horizontal axis, moving cone, balance wheel, eccentric sleeve, upper broken wall (fixed cone), lower broken wall (moving cone), hydraulic Coupling, lubrication system, hydraulic system, control system and other parts.
The working principle of the cone crusher: When the cone crusher is working, the rotation of the motor is rotated by a belt pulley or a coupling, a cone crusher drive shaft and a conical crusher cone under a urging of the eccentric sleeve. Therefore, the broken wall of the crushing cone is close to the surface of the rolling wall fixed on the adjusting sleeve, so that the ore is continuously subjected to impact, pressing and bending in the crushing chamber to realize the crushing of the ore. The motor drives the eccentric sleeve to rotate by the bevel gear, so that the crushing cone rotates. The crushing cone is sometimes close to and then leaves the fixed cone to complete the crushing and discharging. The joint between the support sleeve and the frame body is pressed by the spring. When the crusher falls into a non-breakable object such as a metal block, the spring is compressed and deformed to discharge foreign matter, thereby achieving insurance and preventing damage to the machine.
When the cone crusher passes through the crushing chamber or the machine is overloaded for some reason, the cone crusher spring insurance system realizes the insurance, and the cone crusher discharge port increases. The foreign matter is discharged from the crushing chamber of the cone crusher. If the foreign matter is stuck in the ore, the clearing system can be used to continue the enlargement of the ore discharge, so that the foreign matter is discharged from the crushing chamber of the cone crusher. Under the action of the spring, the cone crusher automatically resets the discharge port, and the cone crusher machine resumes normal operation. Crushing cavity surface covered with wear-resistant high manganese steel liner plate. The size of the discharge port is adjusted hydraulically or manually.
Seven, roller crusher
The roller crusher is divided into three types: roller crusher, counter roll crusher and double roll crusher. It is suitable for crushing medium hardness materials such as limestone in industrial sectors such as cement, chemical, electric power, metallurgy, building materials and refractory materials. , slag, coke , coal and other materials in the medium, fine crushing operations. This series of roller crushers is mainly composed of roller, roller support bearing, pressing and adjusting device and driving device.
Double roller crusher working principle:
Adjustment of the discharge granularity: a wedge or washer adjustment device is arranged between the two rollers, and the top end of the wedge device is provided with an adjustment bolt. When the adjustment bolt pulls up the wedge, the wedge pushes the movable roller away from the fixed wheel. That is, the gap between the two rollers becomes larger, and the discharge granularity becomes larger. When the wedge is downward, the two rollers of the movable roller become smaller under the action of the pressing spring, and the discharge granularity becomes smaller. The gasket device adjusts the size of the discharge by increasing or decreasing the number or thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge granularity becomes smaller. .
Roller Crusher Introduction:
The tooth roller crusher is a new product designed and developed according to the structural principle of the United States Gangrak crusher. The machine has the advantages of small volume, large crushing ratio (5-8), low noise, simple structure and convenient maintenance, high productivity (1-2 times higher productivity than the current 2PGC toothed roller crusher in China), and the granularity of the crushed material. Uniform, low crushing rate, convenient maintenance, sensitive overload protection, safe and reliable.
The tooth roller crusher is suitable for coal, metallurgy, mining, chemical, building materials and other industries. It is more suitable for the crushing of raw coal (including vermiculite) in large coal mines or coal preparation plants.
The tooth roller crusher has a large breaking capacity, and the motor and the speed reducer are connected by a limited-type fluid coupling to prevent power overload and sensor overload protection, which is safe and reliable. The pitch of the toothed rolls is hydraulically adjusted, and the toothed roller bearings are concentrated and lubricated. The tooth shape is optimized, the shearing force is selected to be broken, the efficiency is low and the consumption is uniform. The birth of the PCM toothed roller crusher completely replaced the existing 2PGC toothed roller crusher in China.
The tooth roller crusher is divided into two series: double-toothed roller crusher and four-tooth roller crusher. The double-toothed roller crusher is a mechanical spring type (2PCM). The toothed roller crusher can be based on the characteristics of the crushed material and It is required to use a coarse-toothed roller or a medium-toothed roller, and the four-toothed roller crusher is actually composed of two double-toothed roller crushers.
