The Double Stream Mill, type PSKM for the Cellulose Industry

Gentle Pulverizing of Dry Cellulose Ethers

Pulverized cellulose ethers are very well suited as a base material i.e. during the production of tablets, colors, extracts blasting- and fixing agents. Furthermore they are used as fillers, as anti-caking and flow aids or as a substitute for fat. The distinctive water binding ability is often used in the construction industry during the processing of cement, gypsum etc. Cellulose ethers are effective as gray- and discoloring inhibitors in washing and cleaning detergents. For these fields of application, the dry cellulose ethers must be pulverized gently and with a defined particle size distribution, for which the ORIGINAL PALLMANN Double Stream Mill, type PSKM is the optimum solution.

Method of Operation

A feed screw transports the cellulose ether into the inlet of the Double Stream Mill, type PSKM. The fan action of the multiple beater impeller suctions the feed material through the material inlet chute with an integrated all metal separator to the center of the grinding chamber. The material is dispersed in the air stream and pulverized by means of impact and shearing.

The Double Stream Mill is vacuumed by means of a conveying fan, which transports the pulverized product to a cyclone separator. The downstream screening machine divides the product into two fractions. The coarse material is reintroduced into the pulverization cycle and the finished product is discharged. A filter cleans the exhaust air of the cyclone.
