According to the different discharging methods, wet ball mill can be divided into overflow type and grate type ball mill. Wet grinding ball mill is suitable for the treatment of materials with high moisture content, most of the ore will not produce physical or chemical reaction when encountering water, so it is also suitable for wet grinding.

The major use of the conventional ball milling is to fracture the particles and to reduce the size, which is different from the newly established high energy ball milling (HEBM) method. In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy

Boron nitride nanosheets (BNNS) exfoliated by physical or chemical methods frequently exhibit poor dispersity in common solvents due to incomplete exfoliation and a low degree of functionalization, which has severely impacted BNNS application performances as polymer and lubricant additives. In this work, we mechanically exfoliated the bulk boron nitride into nanosheets through a ball-milling
