focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for general-purpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.
