Powder homogenization using a hammer millYeung1979

The hammer mill would not serve as a mixing machine under most circumstances because of the low holdup capacity. Grinding of pure materials was preferable to mixture grinding since active ingredients could be lost during the milling operation. Remixing was always necessary following comminution of the mixture in the hammer mill.

Mill (grinding)Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water ().
