Principle of Ball Mill Operation. The ball mill operates by rotating a cylinder horizontally and partially filled with balls. The cylinder's rotation causes the balls to cascade and fall back into the mill, generating impact and friction against the material to be ground. The following are the key components of a ball mill: 1.
