Abstract In the cement industry, high pressure grinding rolls (HPGR) has been used since 1985. At the first appliions, this equipment has been installed in the existing cement grinding circuits as an open circuit precrusher in order to crush clinker especially. The cement factories produce different type of cement by using basically clinker, gypsum and additives like limestone and trass.

[PDF] DETERMINATION OF THE NIP ZONE ANGLE IN HIGHPRESSURE .
A proposal of the nip zone angle determination in highpressure 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 highpressure comminution. Two methods of determination of this maximum pressure were proposed and verified.
