## DETERMINATION OF THE NIP ZONE ANGLE IN HIGH-PRESSURE ...

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. The first method is based on the roll

The crushing-pressure exerted by the opposing roll-surfaces during the angle of nip is instantly released and ceases when the rock-fragments reach the horizontal diameter of the rolls, where the open space between them permits the material to be discharged. Roll- crushing thus permits most careful and accurate stage-reduction within a wide range of sizes, and avoids pulverizing
