Construction and work of overflow ball mill

Apr 19, 2021

May 22, 2019 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

    Sep 13, 2015 If increasing the speed, steel balls are thrown and fall, with impact as the main acting force supplemented by grinding. At higher speed, steel balls will do centrifugal exercise instead of grinding work. When at a lower rotary speed, overflow ball mills have a better grinding outcome. It does the same when the steel balls filling ratio is 40% to 50%
