Stone crusher is necessary for the mining machinery equipment, common stone crusher are jaw crusher, mobile crusher, counterattack crusher, impact crusher, composite crusher, hammer type crusher, vertical crusher, gyratory crusher crusher, cone type crusher, roller crusher, double roll crusher, roller crusher, ball mill, Raymond mill, sand making machine, wash pressure blasting machine, high pressure grinding roller suspension.


Stone crusher is suitable for soft or hard and ultrahard material crushing, plastic, widely used in all kinds of ores, cement, refractory materials, aluminum where soil clinker, carborundum, glass raw materials, mechanism building sand, stone and various metallurgical slag, especially for high hard, hard and wear-resistant materials, silicon carbide, corundum, sintered bauxite, beautiful sand, is higher than other types of crusher yield effect.

In the field of engineering, it is the ideal equipment for the production of sand, cushion material, asphalt concrete and cement concrete aggregate.

In the field of mining, it is widely used in the grinding process, it can produce a large amount of powder ore, reduce the high cost of grinding load.

Impact crusher with excellent low wear properties, the device has high abrasion and disintegration of production by two. In addition, due to the product zero pollution, impact crushing function well adapted in the production of glass quartz sand and other high purity materials, 10-500t / h production capacity range, impact crusher can almost meet any production requirements.

Working principle

Stone crushing machine structure are mainly composed of frame, eccentric shaft, a big belt wheel, flywheel, Hubei, side guard plate, a bracket, bracket back seat, a gap adjusting screw, a reset spring, fixed jaw plate and the movable jaw plate, etc., which toggle plate also played the role of insurance. Cycle the continuous rotation near the series jaw crusher of crushing machine for curved extrusion type motor drive belt and belt wheel, the eccentric shaft so that the movable jaw movement, when the movable jaw rises elbow board and the movable jaw angle becomes larger, thus pushing the movable jaw plate to the fixed jaw plate. At the same time, the material is extruded, rubbing, grinding and other multiple broken; when the movable jaw down, elbow board and the movable jaw angle becomes small, the movable jaw plate on the pull rod, a spring leaves the fixed jaw plate, this time has been broken material from the crushing cavity mouth discharge, with the motor crusher jaw crushing and discharging, realize batch production.

Stone crusher is ore by feeding port to enter, and along the plate sliding down, sieve ore fall process is high speed rotation of the rotor of the hard alloy hammer shattered by and at a high speed along the tangent direction fly to first back plate, the ore continue to be broken, counterattack plate and other ore ore hit back and behind the rotor thrown out of the collision, so in the crushing cavity and ores are repeated impact and crushed. Some ore in the crushing cavity and broken to a certain size, through the gap between the back plate and the rotor and row to the second crushing chamber to by repeated blows, until the particle size becomes small later by a crusher bottom discharging mouth eduction.
