Applications
Neue Herbold ZM series pulverizers are designed for the pulverizing of mid-hard, brittle to high impact plastics that require the final material to be in powder form. Typical applications are PE, PVC, PC and other various types of plastics. The required pulverizer input material must be in a granulate form with a maximum size of 6-8 mm (1/4-5/16 in.).
Design
The ZM series pulverizer (pulveriser) is a extremely high out put unit can be supplied with automatic temperature control. The material to be pulverized is vibro feeder fed into fixed and high speed rotating pulverizer (pulveriser) discs. In conjunction with a integrated inner disc that material is centrifically forced through the pulverizer (pulveriser) discs to the outer chamber for discharge with a down stream material transport system. Neue Herbold ZM series pulverizers (pulverisers) operate without a screening machine. The specific final powder size is dependent on the teeth configuration and the adjustable gap between the pulverizer (pulveriser) discs. In the event that the application requires a maximum particle size, a screening machine can be easily integrated into the system.
Advantages
- extremely high through put rates
- minimal thermal material stress
- longer disc life and reduced re-sharpening costs
- quick and easy disc adjustment and replacement
- cost effective operation

The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm. Material is transferred from the center roll to the apron roll by adhesion. The dispersion is achieved by the shear forces generated between the adjacent rolls. The milled material is removed from the apron roll by a knife that runs against the roll.
