Drying and grinding are generally being done in either air swept ball mill or a vertical mill. The selection of mill system will depend mostly on the factors like initial capital cost, drying and grinding capacity required, cost of energy (power) etc. Coal Fineness: It is understood generally that the finer we grind, the easy it is for burning. However, the fineness required will always be
Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. Fully air- swept mills (5-6M/sec) can dry up to 12-14% moisture.
