Roll Crushers Pressure

A roll crusher incorporates gas hydraulic springs to maintain the desired spacing between the crushing rolls and to provide overload protection. Featured are separate hydraulic means for backing off and then reapplying the hydraulic springs by altering their overall lengths so that roll spacing can be readily adjusted.

Non-uniform nip pressure: See above. Crushed roll. Sometimes called a "baggy sock roll" and is the result of stacking rolls on end in an excessively high pile which in turn causes the lower rolls to fail in an axial direction. Excessive axial pressure: Stack rolls to a more conservative height. Winding too soft: Wind rolls harder. Dished roll
