agitating mill
Experimental research was made on the superfine comminution by an agitating mill with 0.5 ~ 2.0 mm ceramic ball of zirconium oxide as grinding media. The best operational parameters were determined through the conditional tests on the media/material ratio,pulp density,media proportioning and media volume rate and a superfine silicon dioxide powder with a fineness of d_(50) =0.3342 μm was
Experimental study on the grinding rate constant of solid
The mill used in this experiment is made of alumina with an inside diameter of 144 mm and an inner volume of 2100 cm 3, and the grinding ball is also made of alumina.Five ball diameters ranging between 3 and 30 mm were used, and feed size was varied in the order of 10 −3 to 10 −1 as a ratio of ball diameter. Feed sizes and ball diameters used are shown in Table 2, Table 3, Table 4.

STEEL. Steel Shot: There are many sources for steel shot but all are not equal since much of the steel shot is used for shot peening. Make sure that the shot is designed as a grinding media or it could tear up the mill. Steel shot is one of the least expensive grinding medias with the benefit of high density and the availability of a wide range of sizes for small media.
