54. Jan 23, 2022. #2. The typical throughput on every modern crusher is a 6 to 1 reduction ratio, gyrator, jaw, and roll. The exception is a hammer mill. A hammer mill will reduce to finer sizes due to no "nip" angle associated with the others. Check out Mount Baker Mining and Milling, Or if you have a steel shop, make your own.

Read OnA proposal of the nip zone angle determination in high-pressure grinding rolls (HPGR) crush- ing process is presented in the paper. Knowledge of the nip zone angle value makes it possible to deter- mine the real maximum pressing force in the high-pressure comminution. Two methods of determination of this maximum pressure were proposed and verified.

Read Oncontact angle. Nip compaction proved difficult to calculate because of difficulties in measuring fibre rate. For the adopted method to calculate nip compaction, the time to mill the feed blanket was measured from the time when the roll load measured on one side of the mill exceeded 20 kN until the time
