b) Feed Preparation – With more widespread use of coarse ball milling it is increasingly important to present a suitable feed material topsize to the ball mill. Significant inefficiencies are introduced as a result of the need for larger (and, as a result, fewer) grinding balls. Furthermore, as mill performance is related to the complete size distribution of the feed material, all ...

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

Please find below two calculators for sizing mills using the Bond and Rowland methods: Ball mill sizing: Calculator for ball mill(s) in a single stage circuit. Rod ball mill sizing: Calculator for rod mill(s) as first stage of the circuit and ball mill(s) as second stage of the circuit.

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.
