Simultaneous Drying and Pulverizing of Moist Cellulose Ether with the Turbofiner, type PLM

Product Gentle Drying and Grinding of Moist Cellulose Ether

After the reactor, the cellulose ether is of elastic to plastic consistency. A fine and dry powder is necessary for the further use of the cellulose ether as a consistency regulator in construction in building materials and colorants. The ORIGINAL PALLMANN Turbofiner, type PLM allows the product-gentle pulverizing and simultaneous drying of moist cellulose ethers with a starting moisture of 20 to 70% of the weight.

Method of Operation

The material is fed via an airlock into the hot air stream and the mill. A distribution wheel takes the air-material mix and distributes it evenly across the circumference of the grinding zone.

Size reduction is performed in high turbulent airflow by micro whirls. The pulverized material is pneumatically transported. The degree of pulverization is determined by the retention time of the material in the mill, depending on the air volume, as well as the speed of the rotor and the type of grinding elements.
