Here the Coal comes via a belt conveyor into the raw coal bin. From here it is measured and goes to the vertical Mill. After grinding it is air swept and part goes to the Electro static separator. From here the fine coal goes to the Coal bins, feeding coal to the pneumatic screw pumps, one and a standby for the kiln and the other for the calciner.

Mar 01, 2013· In the present work, a novel nonlinear coal mill model is derived for modelbased real time applications based on a former study (Mercangoez Poland, 2011). One of the objectives is to consider a tradeoff between model complexity and model accuracy based on real measurements from an actual hard coal burning power plant to validate the results.

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 ...

Abstract: The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.
