Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between media shape and mill power. The objective of this dissertation was to investigate how media shape

This study investigated the eects of three media shapes cylpebs, spherical and worn balls on load behaviour and mill power draw at various mill speeds and load lling. An inductive proximity probe was used to determine the load orientation of the grinding media
Oct 01, 2020 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.
But, spherical balls remain the most efficient grinding media. Finally, an optimal mixture made of spherical balls and grinding media of different shapes, namely cubes and Eclipsoids that are cheaper to manufacture can be used in the grinding process alternatively to 100 balls.
