PM pulverisers are used for regrind and virgin plastic materials alike. Typical applications include PVC for the pipe and profile extrusion industry and PE for rotational moulding and compounding applications. Material is fed into the grinding chamber by a variable speed vibratory feeder and is ground between one static and one rotating disc.
Final powder size is determined by the gap between the static and 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 and oversize material automatically returned to the grinding chamber.
One-piece grinding disc
The one piece design - serrated disc - ensures lower replacement costs. The installation and setting of the disc is fast and uncomplicated.
Latest bearing technology
The single drive system operating at high speed and 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 and 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.
