The hot air required for drying the coal inside the mill is drawn from the grate cooler. For dedusting the gas from coal mill, a bag filter is used. The collected dust is fed back to fine coal hopper. The clean gas from the bag filter is vented through stack no. 5. ... Energy and Exergy analysis of the Raw Mill .
Hot primary air for drying and coal ... Depending on the required coal fineness, there are two types of classifier that may be selected for an MPS mill. The SLS dynamic classifier, which consists of a stationary angled inlet vane assembly ... Since the first application using an MPS mill to process pulverized coal in Germany in the mid 1960s,
Jun 09, 2013· Coal from travelling belt of raw coal feeder drops in central feed pipe ( connection between Raw Coal Feeder and Mill). After coal reaches Mill bowl grinding started and hot air also been given to make the pulverised fuel dried enough to classifier chamber. The portion of the coal which cannot be grinded finds its way to mill reject.
Cold Air Locking at Mill Inlet: This is very important for coal mill, as ambient air throttling the drying capacity of mill as well as increases the oxygen content of kiln gases making it riskier. Oxygen percentage of more than 1214% is considered catalyst for fire/explosion risk.
The mill outlet temperature directly impacts the dry gas loss in boiler which is a major loss. This depends on the moisture level in coal, the higher the moisture level the quantity of hot air required in mill for the same mill load is higher. In fact in cases where moisture levels are very high the tempering air required .
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 ...
coal vertical mill hot air temperature. Coal mill hot air inlet temperatures should never be more than 600 ° F and the outlet temperature should not exceed 200°F on Raymond coal mills If the flow of raw coal to the coal mill is interrupted for any reason (for example: plugging, failure of the coal feeder, etc), the outlet temperature of the coal mill can quickly climb to .
