Ball Mill for Sale. APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principle is that the total weight of the charge in the mill-the sum of the weight of the grinding media the weight of the material to be ground and any water in the mill—is a function of the percentage of the volume of the mill it occupies. Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7-25 mm) were used in various proportions with balls. The optimum proportion of pebbles by volume was found to be about 25 . Substantial savings in power and ball consumption were achieved with no loss in grinding capacity.

### Accurate Scale UpIsaMill™ Advantages Isamill

In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball mill. The mill scales up accurately on both a power and product size distribution (PSD) basis. A test program must rigorously account for Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40 by volume the rotation rate was equal to 85 of the critical speed. Balls were made from steel S4146 extra high quality having hardness 62 ± 2 HRC according to Rockwell.
