Impact crushers
In this class of crusher, comminution is by impact rather than
Compression, by sharp blows applied at high speed to free-falling rock. 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. These forces are
Increased by causing the particles to impact upon an anvil or breaker plate.
