Ball Mill VS Rod Mill Xinhai
Ball Mill VS Rod Mill. For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption. But for rod mill, grinding effect is better which need...

Steel Ball Mills and Milling Equipment | Paul O Abbé
Steel Ball Mills. 1. HIGH EFFICIENCY – Due to the relatively slow rotational speed but large mass of media, more of the energy goes into milling and less wasted as heat. 2. NARROW PARTICLE DISTRIBUTION – Solids milled in tumble mills are normally so fine and consistent in size that it's rare to require classification.

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.
