It was observed that grinding media shape (spherical, eclipsoids, cube, cylpebs, etc) can influence the performance of a tumbling mill. The media can directly affect the breakage rate, mill load behavior, power draw, and generally energy consumption. In other words, there is a strong relationship between the type of media and the grinding costs ...

The effect of ball milling process on the properties of the natural local clay including structural changes and adsorption capacity for the removal of Ni(II) ions from aqueous solutions, was investigated. The local clay was ground at varying times from 5 to 20 h with a 10:1 or 20:1 weight ratio of the balls to powder, which produced six different ball milled clays (BMClay1 to BMClay6).
