Abstract
This invention relates to industrial production of fine dispersed powders, where the material to be pulverized is mixed with high-pressure working into a gas-solids suspension, which through acceleration nozzles () is conveyed to the pulverizing chamber of counterjet pulverizer () for autogenous pulverization. The method is known in that the pulverized gas solids suspension is conveyed in the pulverizing circle at least to one intermediate tank (), where the gas is removed from the blend and solids are collected into intermediate tank (), which are returned together with new raw material for pulverization till in the equipment a wanted circulation load is achieved, whereafter the process continues so that from it as much ready product is removed as new material is added to it.
