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 Ad this can be used to establish the essential features of a model for mill power.

Introduction: Ball mill is an efficient tool for grinding materials into fine powder. The ball mill is used to grind many kinds of mine and other materials. It is widely used in building material, chemical industry etc. There are two ways of grinding, the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.

The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process. Furthermore, by ...
