Devises Of Unit Operation Such Ball Mill

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

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
