A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
Technical parameters: 1. Each tank maximum loading quantity: milling tank volume threequarters (including the ball) Feed particle size: soil material≤10mm, other materials≤3mm 2. The material particle size: minimum to μm. Rated Speed: revolution (tape) from 0 to 290 r/min rotation (ball mill jar): 0 to 580 rev/min. 3.

Mineral liberation from ores is an important step in mineral processing. It is necessary to grind the ore to extremely fine size to liberate the mineral from such ores. The planetary ball mill is promising in that it makes grinding to submicron sizes possible by imparting high energy to the ground powder. In this context, there is a need to understand the dynamics of ultrafine grinding within ...

1. Introduction. Planetary ball mills provide high energy density due to the superimposed effect of two centrifugal fields produced by the rotation of the supporting disc and the rotation of the vials around its own axis in the opposite direction [1].During operation, the grinding balls execute motion paths that result in frictional and impact effects.
