Appli ion of value engineering techniques to grinding process modelling led to the identifi ion of two basic functions of the ball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between “coarse” or oversize material and “fines” or undersize material these basic functions are a breakage of the coarse material and b removal
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters 10 feet diameter inside liners the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos Allis-Chalmers

Selection Sheet - Eaton. Ball mills - These mills use forged steel balls up to 5 inches Use of a clutch permits the mill motor to be The required clutch torque is calculated from the power rating of the mill motor clutch shaft rpm and an appropriate service factor.
Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today’s global markets expanding mining groups are trying
