- 5 Ways To Improve Grinding Efficiency Of Ball Mills News /12/260183;32;Mill Geometry And Speed. According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times.Ball Mills an overview ScienceDirect Topic

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

To offer a solution, RETSCH developed the High Energy Ball Mill Emax which is able to grind many different substances to particle sizes lt; 100 181;m and usually in a much shorter time than required by other ball mills. Ideally, the grinding breaks can be skipped altogether, which results in enormous time savings.

Schellinger39;s calculated ball mill efficiency, in dry or wet ball mill grinding, ranges between 10% and 19%, with the higher figure occurring at the optimal mill loading. In terms of the Brace and Walsh surface free energy of quartz, his results give a ball mill efficiency that is less than 0.5 %.
