Impact crusher’s working theory,
The Material fall down from the hopper into the high-speed rotation of the crushing chamber, impeller, the impeller rotating at high speed, the material under the action of centrifugal force at high speed, impact and crushing with another part of the diversion of materials produced in the impeller speed, after impact each other, they will friction and grinding again and again between the impeller and the casing a vortex form several times , discharge from the port created a closed loop ,then controlled by the screening equipment and get the required product size.
