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".Web

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".Web
