DETERMINATION OF THE NIP ZONE ANGLE IN HIGH

A 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.
