### Effect of pre-crushing with a vertical shaft impactor

1 Introduction. High pressure grinding roller (HPGR) crushers are used conventionally as a pre-crusher ahead of the ball mill to reduce the specific energy consumption of the grinding stage or to increase the grinding capacity of the circuit in cement grinding circuits 3 4 5 .

Service Online### Experimental Study on the Grinding Rate Constant of a Ball

We investigated tlte effects of ball diameter and feed size on the rate constant when the ball mass feed mass and the mill s rotational speed were constant. The results indicated that the grinding rate constant can be expressed by modifying the equation that was proposed by Snow as the function of ball diameter and feed size. 1.

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs
