Size reduction machinery specialist Neue Herbold of Reihen, Germany has introduced a new range of pulverisers for semi-rigid, brittle and impact resistant plastic materials where a consistent uniform powder is required.

A global specialist in size reduction machinery including the ZM pulveriser range, Neue Herbold’s equipment range includes granulators (pipe and profile), grinders, pulverisers, screw shredders, hammer mills, shredders, polystyrene shredders and guillotines.

The pulveriser is typically used to pulverise PVC, PE, PC and various types of plastic materials, and has the ability to process up to 900kg per hour. The final pulverised material when blended with virgin material ensures consistent feeding and processing of the extruders.

Granulates of 6-8mm are fed via a vibrofeeder, to a high speed rotating disc that creates a powdered product sized 300-1000 microns based on specific size requirements.

Plastic granulate is fed centrally between the fixed and high speed rotating high alloy steel pulveriser discs, with the centrifugal effect carrying the material through the processing zone before being discharged from the machine pneumatically. The particle size of the product is determined by the type of material being processed, the disc construction and the processing gap between the discs.

Key features and benefits of Neue Herbold pulverisers include long service life of the discs between resharpening intervals; fast and easy replacement and adjustment of discs; low residence time equating to lower thermal stress on the process material; and cost-effective operation.

Neue Herbold is represented by HBM Packaging & Plastics Technologies in Oceania.
