Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed Attrition mill. The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media.
BOWL MILL BOWL MILL. Coal is fed from the bunkers by drag link feeder. The coal falls on the mill grinding table and is carried under the spring loaded, free running grinding rolls, which reduce the coal to pulverised fuel of the required fineness. Hot primary air is fed to the mill which carries the finely ground coal to the classifier. These passages surround the lower part of the mill.
If high pressure steam is used, plant efficiency is increased because lesser quantity of steam is required for generating a given power;, work done per unit mass of steam is higher. Forced circulation of water can be used which helps arrangement of furnace and water surfaces and reduction of heat exchange area.
