hammer crusher partscrushing chamber, rotor shaft, frame, impact hammer, grate bars, motor, flywheel, grate, pallets and lining, dust seal, overload protection device. hammer crusher working principlematerial are fed into the hammer crusher, that is subject to rotation, high-speed impact and collision are broken. qualified crushed Oct 01, 2017 the high speed rotor throws the ore to the outside of the crusher. crushing results from interparlicle collisions and from ore striking the hammer or material bed that forms at the periphery of the crushing chamber.Working principle of vertical shaft impactor is totally different than horizontal shaft impactor. it has a high speed rotor with wearing resistant tips and main chamber crushing chamber is designed in such a way so that speed rotor throw the rocks against the high crushing chamber.The materials drop into the hopper, and then enter the rotor rotated with high speed through the central feeding hole and are fast speed up and cast out of the rotor. firstly they will be impact with parts of the crushing chamber, and then change the direction upward to Feb 03, 2021 meka mvi90 crusher has a tested and proven rotor that functions like a high-speed dry stone pump that launches rocks at a continuous pace. the material fed into the machine accelerates in the rotor, and is continuously launched inside the crushing chamber at speeds of 50–75 msec. .Vsi crushers use a different approach involving a high speed rotor with wear resistant tips and a crushing chamber designed to throw the rock against. it is accelerated in high-speed rotor, and then is thrown out at speed of 60-75ms. when hitting anvil, it is crushed. final products come downwards though outlet.
