Abstract
In the few studies devoted to increase the grinding efficiency of a Tower Mill Pulverizer, it has been possible to produce particles finer than 10μm. The problem now is to increase effectively the weight of fine particles in the products. To achieve this goal the weight and particle size distribution of products, and also the electric consumption of the Tower Mill KD-3 were investigated by varying the speed of the stirring screw from 1.08 s-1to 1.58 s-1.The results of the tests can be summerized as follows:(1) The weight of products in the classifying column and the cyclone, and the electric consumption of the stirring motor increase with the speed of the stirring screw, while the specific energy (J/kg) remains constant.(2) The particle size distribution of the products in the classifying column and the cyclone are not influenced by the stirring screw speed.
