each pipe is not uniform. device is needed to control the coal flow to each pipe to correct the coal flow imbalances. typical implementations of centrifugal classifiers are shown in figure in a vertical pulverizer and a ball tube mill with external classifier. figuredec 13, 2011 ball tube mills are either pressurized or suction type. In the pressurized type, the hot primary air is used for drying the coal and to transport the milled coal to the furnace. In this type, leakage in the mill area is high.in the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone.ball race type coal pulverizer mill specifications. 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 model in the savree database represents a vertical grinding bowl millother grinding mill types include the ball tube mill, hammer mill, ball and
