Concept Behind Ball Milling

May 22 2019 the ball mill consists of a metal cylinder and a ball the working principle is that when thecylinder is rotated the grinding body ball and the object to be polished material installed in the cylinder are rotated by the cylinderunder the action of frictionandcentrifugal force at a certain height it will automatically fall and impact and grind the material in the cylinder to grind the material
