The proportion of grinding media is another factor affecting mill operation. It has undergone an important evolution lately. Originally it was considered that a SAG mill should work at 810% ball content. Lateron, larger mill sizes and larger processed tonnages have led to operations at 1014% level.

Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

A generalized SAG mill power draw equation developed by Austin, is given by: where the parameters used in the model are defined as: mp= net mill power (kW) K = a constant (kW/ton ) D = mill internal diameter (m) L = mill length (m) J = fractional volume of mill filled by total charge. εB = effective porosity of the total charge.

The grinding circuit (Fig. 1) used for the present study is part of a copper concentrator plant. The system consists of a ball mill, hydrocyclones, pulp sump and associated pumps and solids feeding conveyors. The feed, copper ore (from primary crusher, size 3 in) is fed into the ball mill by vibratory conveyors.

The Ball mill sump level is allowed to change over a specified range so that minor variations in production rate are managed in the sump. This approach avoids unnecessary changes to the cyclone pressureor the number of cyclones in serviceresulting in increased stability of the cyclone pressure and the P80 to the flotation cells.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
