The first step in the manufacturing of lime is to crush the pieces of limestone to make them smaller. There are two basic types of primary crushers: compression and impact. Compression crushers use slow, steady amounts of pressure to reduce the size of the rock, whereas impact crushers rely on intense, repeated blows. Compression crushers are used
