Tips to maximize crushing efficiency - Pit Quarry : Pit ...

2019-5-13  The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed.

DETERMINATION OF THE INFLUENCE OF JAW

2019-2-8  Abstract: In the paper, in accordance to the theory, it is shown that the relative energy consumption of a jaw crusher depends on the average diameter of the material entering the crusher and the width of the discharge port. An experimental study has shown that the energy consumption depends also on the frequency of the jaw swing. In the study a jaw crusher with a complex swing of a moving jaw is used and it is driven by

DETERMINATION OF THE NIP ZONE ANGLE IN HIGH

2012-10-4  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.
