Introduction. This article concerns itself with vertical grinding mills used for coal pulverization only (coal pulverizers), although vertical grinding mills can and are used for other purposes.. The 3D model in the saVRee database represents a vertical grinding bowl grinding mill types include the ball tube mill, hammer mill, ball and race mill, and, roll and ring mill.
The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion. Advantages. Good control on coal fineness.
