Operations covered in this report include run-of-mine coal breaking, coarse coal cleaning, fine coal cleaning, live storage and blending, fine crushing (crushing to top sizes ranging from 1/4-inch to 20 mesh), drying, and grinding (70 percent minus 200 mesh).
The consumable parts are made of high chromium cast iron from Kurimoto, a manufacturer of wear-resistant special steel, to extend their service life. This system doubles the continuous operation time of consumable parts compared to conventional systems. The unique structure enables crushing of raw materials of comparatively high moisture content.
The capacity of coal crushers (available upto 600 tons per hour) must be sufficient enough to meet the peak load requirements. The crushed coal is passed over the sizer (generally vibrating screen) which removes over sized coal and feedback to the crusher. The sized coal is then further passed on to the drier to remove the free excess from the

The Analysis of Influence of the Gangue in the Coal as
There is actually the coal gangue with hard texture and hard to grind in the coal pile. The coal gangue will have adverse effects on the fine screening machine, fine crusher and other equipment. After burned this type of coal, the fluidized quality of the boiler bed is degraded to make an impact on the safe and stable operation of the boiler.
Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll crushers used for minerals and metal ores have smooth faced rolls.)
