Q Amp A On Vertical Mill And Ball Mill For Coal Preparation

what effect does the comprehensive utilization Of pulverized coal vertical mill and ball mill have On grinding process. generally speaking, the vertical mill can realize the functions of crushing, grinding and classifying. single vertical mill can process the coal powder. the ball mill is more suitable for small beneficiation production fig. schematic diagram of coal mill the mass of coal to be pulverised depends on the mass flow of the raw coal, the return flow of the particles rejected by the classifier, and the grinding rate which is proportional to the mass of raw coal on the grinding table, the mass of pulverised coal production process flow chart. the raw coal is stored in the raw coal bunker and fed into the vertical mill by the belt weigher in bottom of raw coal bunker. after drying, grinding and powder classifying, the coarse coal powder with unqualified size will be fall down onto the millstone again for grinding.coal gangue is the solid waste discharged in the process of coal mining and coal washing. It is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal formation. vertical roller mill is specialized in grinding coal mine, cement industry, slag, coal gangue, steel slag
