Coal Crusher: Generally, require when ball mill is used for grinding and raw coal size is on higher side(>25mm). Conveying to Hoppers: Covered belt conveyors, horizontal or inclined are most suitable and commonly used for conveying.
10/9/2015 Solid fuel that spills over the bowl and into the area below the bowl can cause a fire since it is exposed to the hot drying air entering the coal mill. The coal mill scrapers will usually sweep the fuel pieces around to the debris chute and discharge them; however, a fire is likely to occur if a coal buildup occurs at the hot air inlet to the mill.
