The ball mill is the key equipment to crush the material after being crushed. This type of mill is equipped with a number of steel balls in its cylinder as grinding medium. When the barrel rotates, the grinding medium is attached to the wall lining of the barrel due to inertial centrifugal force.
Ball mills generally work in a dropped state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. In order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in
