Step 1: Wetting. The first step to wet grinding is eliminating air from the surface of the raw feed, so that each individual particle is fully in contact with the liquid slurry. Ensuring complete contact is vital for effective milling. This requires a liquid with lower surface tension than the free surface energy of the solid.

Ball grinding can be carried out in either dryoperation or wetoperation. The former is widely used in coalfired power plants and cement industry, and the latter is widely used in metal and nonmetal mines. There are three types of mills used: grate ball mill, overflow ball mill, and peripheral discharge ball mill.

A jet mill consists of a short cylinder, meaning the cylinder's height is less than its diameter. Compressed gas is forced into the mill through nozzles tangent to the cylinder wall, creating a vortex. The gas leaves the mill through a tube along the axis of the cylinder. Solid particles in the mill are subject to two competing forces:
