22 May, 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 ...
The high energy ball milling devices are of three types namely: shaker mills, attrition mills, and planetary ball mills (Suryanarayana 2001). Shaker mills have a vial where grinding media,, milling balls and sample are swung vigorously toandfro for several times causing an impact of milling ball against each other, with the sample and ...
