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.
There are different types of steel ball mills, they are, cast nickel alloys, stainless steel. They are usually applied in the grinding process of copper, gold, iron ore and polymetallic. Steel ball grinding media are used in tower mills, Isa mill, rotary mills, semiautogenous grinding (SAG) mill. Plastic Grinding Media
