Driving Device: Including motor, reducer, coupling, etc., used to drive the drum to rotate. Feeding and Discharging Device: Used to convey materials into the drum or discharge processed …

A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows:

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. ...

Tumbling mills are machines used in mining, chemical, and construction industries to reduce the size of solid materials by using the principle of impact and attrition. They consist of a rotating cylinder, which contains a charge of loose grinding media.As the cylinder rotates, the grinding media falls, collides, and crushes the materials inside the cylinder.
