Bowl Mill Pulverizer. Less than desired mill performance after all mechanical and maintenance variables are addressed may be due to marginal pulverizer capacity or coal quality different from the pulverizer capability or design. Pulverizer modification is sometimes required to achieve desired fineness and fuel balance.
A bowl mill for a coal pulverizer with an air mill for primary entry of air, comprising a substantially closed separator body ( 2 ) having a central axis; and a bowl-like grinding table ( 3 ) mounted on a shaft ( 4 ) rotatable about said central axis, cooperating with a plurality of grinding rolls ( 6 ). The airmill is provided with multiple.
Nov 17, 2012 . Bowl Mill Bowl mills are employed to pulverize the pre-crushed raw coal to the required fineness before it is admitted into the boiler furnace for combustion. The mill output can be easily varied, as per the turndown ratio from its minimum to maximum load. Crushed raw coal at a controlled rate is fed into.
. 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.
