  • The working principle of ball mill Meetyou Carbide

      The ball mill consists of a metal cylinder and a ball The working principle 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 At a certain height, it will automatically fall and impact   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 sizeBall Mill: Operating principles, components, Uses 34 行    Ball Mill Working Principle To be chosen according to the grinding Ball Mill Working Principle And Main Parts GitHub Pages
