desin of optimum performance bowl mill

BHEL PRESENCE IN COAL MILLING EQUIPMENT

Bowl Mill is basically a vertical Mill rotating at Moderate speed (30 to 60 RPM) about its axis. It is recognized as the most advantageous design of the coal pulveriser because of its low initial cost, low maintenance cost, removal of tramp iron, low power consumption, easy maintenance, wide range output & quiet operation.

Optimum ratio between length L and diameter D, L:D is, usually, accepted in the range 1.56–1.64. The mill productivity also depends on many other factors: physical-chemical properties of feed material, filling of the mill by balls and their sizes, armor surface shape, speed of rotation, milling fineness and timely moving off of ground product.
