What is a Primary Crusher?
A primary crusher breaks up large pieces of rock or concrete from the blasting or excavation process and turns them into smaller, more manageable chunks. This is the first step in the crushing process. The smaller pieces can then either be pre-screened or fed directly into a secondary impact or cone crusher.
