PM pulverisers are used for regrind & virgin plastic materials alike. Typical applications include PVC for the pipe & profile extrusion industry & PE for rotational moulding & compounding applications.
Material is fed into the grinding chamber by a variable speed vibratory feeder & is ground between one static & one rotating disc.
Final powder size is determined by the gap between the static & rotating disc which is easily adjusted external from the grinding chamber.
Ground material is pneumatically conveyed from the grinding chamber to an optional screening device where good material is bagged off & oversize material automatically returned to the grinding chamber.
One-piece grinding disc
The one piece design - serrated disc - ensures lower replacement costs. The installation & setting of the disc is fast & uncomplicated.
Latest bearing technology
The single drive system operating at high speed & high power has a special bearing arrangement to ensure prolonged production times between bearing service.
The gap between the grinding discs can be easily adjusted to give accurate setting for the required fineness & consistency of product. The system can produce powder sizes to below 500 microns. Depending on the material, there may be no requirement for a screener.
With more than 50 years of experience, ZERMA is one of the leading manufacturers of high quality size reduction machinery worldwide. The name ZERMA comes from the German word zerkleinerungsmaschinen, meaning crushing machine. Since the company was founded in 1943, this has remained our mission.
ZERMA has traditionally focused on the development and production of size reduction machinery for the plastics industry.
