Impact Crusher - an overview | ScienceDirect Topics
These forces are increased by causing the particles to impact upon an anvil or breaker plate. There is an important difference between the states of materials crushed by pressure and by impact. There are internal stresses in material broken by pressure that can later cause cracking. Impact causes immediate fracture with no residual stresses.
