# Ball Mill Working Principle And Calculation

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 and grind the material in the cylinder to grind the material.

• ### Wet Grid Ball Mill Rhyther Mining

When the ball mill cylinder rotates the grinding body acts on the cylinder liner due to the action of inertia and centrifugal force and friction. It is carried away by the cylinder. When it is brought to a certain height it is thrown off due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile. 3.The material is uniformly fed into the first chamber of the mill by the feeding device
