If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.

3. Different grinding medium. The Rod mill usually uses the steel rod with a diameter of 50100mm as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium. The steel balls of ball mill are in point contact, while the steel rods of Rod mill are in linear contact, so their working ways are obviously different.

SAG Mills use a combo of ball milling and autogenous (letting the material crush itself) milling. They do have balls in them, but usually less of a load of them (820% load) than a ball mill (typically around 30% loaded). They also have plates on the inside that lift the load up and tumble it, like a dryer does.
