Run of Mine (ROM) materials are brought directly from blasting projects and crushed a primary crusher for the first round of crushing. At this point, the material receives its first reduction in size from its raw state. Primary crushing produces materials ranging from 50" to 20" on average. The two main types of primary crushers are: Jaw crushers
Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
