The medium-speed coal mill The medium-speed coal mill is one of the series of pulverizing equipment produced by Heavy Industry Technology. It is widely used in the pulverized coal pulverizing system of bituminous coal. It is mainly used for grinding of medium-hard materials such as bituminous coal and lean coal.
The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed decreases with mill size and remains constant for a given mill diameter.
The slow speed and medium speed mills are selected for coals ranging from sub-bituminous to anthracite. The high-speed mills are used mainly for lignite. Operation Of Bowl Mill Pulveriser In bowl mill pulveriser raw coal coming from feeder gets ground between the grinding rolls and bull ring segments installed on the revolving Bowl.
