and shape, mostly based on specifications. Most secondary crushers are cone crushers and horizontal shaft impacts. For coal, many times, rotary breakers are used as primary crushers and ring granulators are used as secondary crushers. Information on construction and working of various crushers is given in the following chapters.
The liners are from 50 to 65 mm thick (2″ to 2.5″) with the waves from 60 to 75 mm (2.5″ to 3″) above the liners. The replaceable lifter bar design made of either metal or rubber in about the same design proportions can be used. There could be a loss in power with rubber particularly if the mill speed is faster than about 72% of ...
Coal mill dust collectors have a substantial effect on productivity, yet have received relatively little attention as companies implement cost-saving programs, like the use of petcoke as a fuel reduction measure. Petcoke is typically ground finer than coal, and it has a particularly sticky nature that makes it more difficult to clean from ...
