Precision Knife Mill, type PSC for the Cellulose Industry

Production of High Quality Cellulose Powders

The ORIGINAL PALLMANN Precision Knife Mill, type PSC allows the processing of cellulose in roll and sheet form as well as loose material.  The  fine  cellulose powders are used as fillers in the plastics- and rubber industry and are otherwise used in molding compositions as a filter aid or as the basic material for the production of cellulose ether.

Method of Operation

Rolls, sheets and strips are transported into the cutting chamber by means of profiled draw-in rollers. Precut material is fed via a feed chute. Size reduction to the desired end size is performed between the stator- and rotor knives in the housing. The end fineness is determined among others by the speed of the rotor and the type of screen insert. High-speed models with special rotors and screens are used for continuous pulverization of sheet- and roll cellulose.

The pulverized end product is discharged straight down out of the cutting chamber, supported by  suction and can be sacked underneath a cyclone or can be transported directly into a bin for further processing.
