The Turbo Mill, Type PP for Coating Powders

Production of Micro-fine Plastic Powders for Metal and Textile Coatings without Cooling Agents

The special design of the PALLMANN mills, such as the Turbo Mill type PP, allows granules from PE, PS, EVA and other plastics to be pulverized at ambient temperature into coating powders.

Method of Operation

The granules are continuously fed into the Turbo Mill, type PP from a storage bin by a vibratory feeder.  A quickly rotating impeller takes the feed material into the grinding chamber and throws it against a counter-rotating baffle plate.  Size reduction is performed by impact and shearing forces.  Depending on the requirements, the profile of the grinding elements can vary.  The fineness of the end product is determined by adjusting the gap between the impeller and the baffle plate.

A Fan sucks the powder out of the mill and conveys it through a cyclone and a rotary air lock into a special screening machine.  The finished pulverized powder is discharged into bags.  Coarse material is returned to the turbo mill for pulverization.
