Pulverisers: The Pulverizer is compatible for the pulverization of semi-rigid, brittle and impact resistant materials that require powdered products. Particles with a size of 6-8 mm are fed through a vibrating screen into a rotating high-speed sawtooth disc to produce a powder product in the desired 300 –1000-micron range, with the final size determined by adjustable disc spacing. Usually used for shredding LDPE, HDPE, UPVC, PC and various other plastics.
