Description

Pulverizers (micronizers) that grind polyethylene, polypropylene and PVC into micronized powder. Granulated or ground plastic is introduced in a controlled manner into the grinding chamber, where it is reduced by friction and impact between a rotor and a disc rotating at high speed; an adjustable screen system maintains the target particle size and a cooling and air circulation unit prevents overheating for stable operation. The fineness obtained depends on the material and the setting, the target being defined case by case. Three models are offered (300, 500 and 800) for low, medium and high throughput. Applications: production of coating powders, rotomolding powder, masterbatch and compounds, recovery of flash and scrap. Processes rigid and flexible plastics, dry or with low moisture.
