Impact Crusher

Introduction of Impact Crusher (Impact Mill)

Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape.

In impact crusher, the moving parts are beaters, which transfer some of their kinetic energy to the ore particles on contacting them. The internal stresses created in the particles are often large enough to cause them to shatter. Impact crushers have a wider use in the quarrying industry than in the metal-mining industry.

In impact crusher, the materials falls tangentially on to a rotor, running at 250 to 500 revolutions per minute, receiving a glancing impulse, which sends to spinning towards the impact plates. The fractured pieces which can pass between the clearances of the rotor and breaker plate enter a second chamber created by another breaker plate, where there clearance is smaller, and then into a third smaller chamber. This is the grinding path which is designed to reduce flakiness and gives very good cubic particles. The blow bars are reversible to even out wear, and can easily be removed and replaced.
