Dec 31, 1993 Batch stirred ball mill grinding results demonstrate that this new technique has a great potential in reducing the energy consumption of fine coal grinding. Depending on the pretreatment conditions, the specific energy consumption of producing less than 10 mum product is reduced to 41-60 of that of the untreated coal feed.
Phrase two drying and grinding 1.Coal 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. 2.For high moisture material, a dryer should be applied to dry the coal before grinding.
In the process of heat exchange between raw coal and hot air, water is continuously evaporated. After the completion of the drying, the coal pieces are sent to the grinding chamber, and the grinding chamber is rotated to bring up the grinding media steel balls and throw them off.
