Wet disc mills generally have simpler mechanical structures and fewer moving parts than traditional ball mills, which can mean lower downtime and operating costs. 3. Abrasiveness. Harder materials may wear out the ball mill more quickly than a sturdier designed wet disc mill, requiring more frequent grinding media changes.

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 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
