Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
Generally, a Quad Roll Crusher is recommended for a medium size feed material, while the Triple Roll Crusher, with its single roll top stage, is effective for handling larger size feeds. These machines do the work normally assigned to two separate crushers. Typical feed sizes range from 18" 72" with final product size of ½" 3".
