Particle size reduction, screening and size analysis

Impact mills use revolving hammers to strike incoming particles and to break or fling them against the machine case. In jet mills, particles strike each other as they are transported in a stream of air or steam. For the initial reduction of large materials, a rotating drum propels the feed into the air where the pieces strike each other and fracture. Mortar and pestle grinding can be
