The measurement of the ball charge volume load or filling degree is essential to maintain the absorbed power of the mill and consequently the mill production
We discuss the types of ball mill the basic principles of the ball mill how it works the details of design including equations for optimum dimensions in all cases some manufacturers for the ball mill and estimation of the cost the ball mill 6 1 Introduction Ball mill is an efficient tool for grinding many materials into fine powder
The optimum ball size distribution is thus determined by the amount and combination of grinding balls of different diameters in the make up charge Grinding media wear caused by the abrasive milling environment necessitates a periodic charging of new grinding balls
In the DEM simulation direct simulation of particle disintegration in milling process is generally very difficult because of huge computational load Therefore collision energy between grinding media balls or grinding media ball and wall was used as a factor of particle disintegration
distribution of ground material in time were analysed and the effect of ball size degree of filling the mill with feed and the number of grinding balls on the process rate was reported This rate varies during grinding and the effect of the above listed factors is different on subsequent stages of the process Key words ball mill point of contacts grinding rate ceramics INTRODUCTION
Efficiency and grinding media filling level and a few others involved in comminution research conducted some preliminary studies on low filling level of grinding media in laboratory ball mills Initial indications were that there was a very good possibility for increased efficiency if ball mills were run with drastically reduced filling levels Unfortunately there was only a verbal
