Wet Milling is a minor operation that is added to the final processing step where the slurry (API/solvent) is run through the wet mill followed by the final filtration and drying. The operation is built into the master batch record, has little/no yield loss, and no separate containment is required outside of normal operations.

Ball mill is a high-energy mill process especially used for an energy-intensive process like mechanical alloying, mechanochemistry, or mechanical activation. Planetary ball mill is used to determine the dependence of process efficiency using milling parameters such as ball size and number, mill geometry, and velocity of the rotating parts.
