Exercise 8 in Demo: Optimizing Ball MillCyclone Circuits The recirculating load in a ball mill circuit affects the final product size as well as the formation of scats/ejection of balls from the ball mill. The variables in a ball mill and cyclone should be optimized continuously to

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. The materials are ground by moving the container. Because the structure of ball mills is simple and it is easy to operate, and so they are widely used.

A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure
