PVC Pulverizers

ZERMA's PM-series disc pulverizers are available in disc diameters from 300 mm to 800 mm. These plastics pulverizers are high speed, precision grinders for processing medium-hard, impact resistant and friable materials. The material to be pulverized is introduced through the center of a vertically fixed grinding disc which is mounted concentrically with an identical high-speed rotating disc. Centrifugal force carries the material through the grinding area and the resulting powder is collected with a blower and cyclone system.  Depending on the application, the machines can be equipped with one-piece grinding discs or grinding segments.

Pulverizing PVC pipe and profile regrind in recycling is one of the main fields of use for the ZERMA PM pulverizers.   Working in line with a shredder and granulator creates a balanced and efficient system to handle in-house production waste.   Another use is the grinding of PE for rotomolding applications.  For this purpose,  the PM plastics pulverizer is used in the production process to create the powder needed in the process. In this process, a screening machine is necessary to ensure the right output size, distribution, and flow properties of the ground material.
