Redesign reject valves, throat rings, classifier vanes, and other internal components as necessary for fuel and application. Perform mill dribble tests to determine minimum throat velocity minimum PA flow. Perform mill response tests to evaluate proper balance of mill primary air/fuel ratio at high load.
Phrase one: raw material crushing Coal blocks will be crushed to 15mm50mm fineness by crusher. Phrase two: drying and grinding material with low moisture will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding. The hot air in the mill will dry the coal. This will reduce drying cost. high moisture material, a ...
Oct 07, 2008· A major waste in a pulverized coal fired power plant is the reject produced from pulverizing mills. When coal is ground in a bowl mill heavy mineral matters are separated, but they still contain a small amount of coal mixed. However, the heating value of the rejects is generally too low for combustion in conventional boilers.
