The coal grinding

Designed for use with ball mills that grind coal, petcoke or charcoal. it is an energy-efficient and well-proven solution which incorporates the experience attained from over 1500 high efficiency dynamic air separators supplied by flsmidth in grinding applications. the rtkm separator is the obvious choice for new coal-grinding ball mills.

Ball mill: single chamber ball mills with classifying liners and dam ring with drying chamber and static or dynamic separator are commonly existing for coal grinding in cement plant for one or more kilns as per capacity. ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe ball mill.

May 01, 2014 it has been shown that mill capacity is linearly correlated to media surface area, thus using 30 mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes. however the fact that the coal feed to this plant is known to be contaminated with a small fraction of hard-to-grind stone, which will strongly ball mill.
