May 22, 2019· Theball millconsists of a metal cylinder and aball. Theworkingprinciple is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.

First, a JarMillgrindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a BondWorkIndex determination, results in a specific energy value (net Hp-hr/t) from an empiricalformula.

Aball millalso known as pebblemillor tumblingmillis 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 themillvolume and its size depends on the feed andmillsize.

The operating principle of theball millconsists of following steps. In a continuously operatingball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...
