Comminution and classification technologies of iron ore

Gyratory and cone crushers were also invented in 19th century, as an alternative to jaw crushers. The cone crusher is a modified gyratory crusher. The material is crushed in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on an oscillating shaft assembly.

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.
