Impact Crusher Overview
Impact crushers are most often used for rock crushing, be also used in the recycling industry to process hard and brittle materials of all kinds. What is important today, in addition to the quality of the end product, is environmental and cost awareness, availability and a wide field of application, Impact crusher should reach all these requirements. SBM developed PF series impact crusher and PFW series impact crusher, which are both larger and operates at a steeper incline than any other similar system, ensuring that the material is cleared quickly in high TPH applications, all while protecting the conveyor belt from damage.
Impact Crusher Working Principle
Impact crusher of concrete crushing form of liberal crushing, rebound crushing, and milling crushing. When crushing material, material dangling dealt hammer blow. If the particle size is small, the impact approximated through the particle's centre of gravity, the item is along the tangent direction free breaking. If the granularity is large, the material thrown not completely broken, will have a rotating, direction and the tangential angle of the throw, was bounced by counterattack, this rebound is broken. After the first impact on the material, material due to the partial destruction and reversing, to discontinue certain paths a regular motion, repeatedly throwing back and forth in impact crusher machine, which is milled broken.
Impact crusher working principle as follows: when the device is working, driven by electric motors, high speed rotation of the rotor. Material entered Board hammer role district Shi, and rotor Shang of Board hammer impact broken, Hou and was throwing to counterattack device Shang again broken, then and from counterattack lining Board Shang play returned to Board hammer role district again broken, this process repeated for, material by big to small entered a, and two or three counterattack cavity repeated for broken, until material was broken to by needed grain degrees, by out material mouth discharge.
Material in impact crusher within of specific run route following: stone by machine upper directly fall into high-speed rotating of turntable; in high-speed centrifugal force of role Xia, and another part to umbrella type way shunt in turntable around of fly stone produced high-speed collision and high-density of crushed, stone in mutual combat Hou, and will in turntable and machine shell Zhijian formed Eddy movement and caused repeatedly of mutual combat, and friction, and crushed, from lower passthrough discharge.
