The hardness of grinding media ball - how to choose balls for

From the way the ball mill works. In the operation environment, the ball mill is divided into two types: wet ball mill and dry ball mill. Dry Ball millwork has a strong corrosion, so as the same wear-resistant grinding media ball, the wear-resistant grinding media ball in the wet grinding efficiency is faster.

High energy ball milling process for nanomaterial synthesis

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling balls in the bowl.
