ZERMA PM
The PM series high speed precision pulverizer are centrifugal mills that are primarily used for the fine grinding of regrind or primary products for pipe, profile or sheet extrusion as well as rotomolding.
General description
The ground material (or new material), which is pre-crushed to approx. 6 mm, is fed via a pneumatic dosing chute and finely ground between the stationary and rotating disk. The material has a final fineness of almost 100 % less than or equal to 1 mm.
The centrifugal force, together with a pneumatic suction system carries the material from the grinding area.
Finenesses of less than or equal to 1 mm are achieved. By using an optional screening machine, it is possible to define the maximum upper limit of the final fineness. The adjustable distance between the grinding disks and the use of segments with different corrugations also influence the quality of the ground material.
Discs with diameters of 300, 500 and 800 mm are available.
An automatic cooling system permanently controls the temperature of the material during the grinding process to prevent thermal damage. The maximum temperature of the material and the amount of water required for cooling are preset.
