MODELING OF THE PROCESS OF COAL GRINDING
Grinding of coal generally uses two types of crush-ers namely the drum crushers and the hammer crush-ers. The drum crushers consist of two parallel set of drums stocked on circumferences of the performances in the form of spikes rotating at high speed in opposite directions. Getting between the rotating drums coal is

Wear resistance of high chromium white cast iron for coal
· The precipitated carbides can be M 7 C 3 and/or M 23 C 6. In high-chromium white cast iron alloys the precipitation occurs from the center to the peripheries of the dendrite. The increase in the volumetric fraction of precipitated carbides over time results in a reduction of the carbon dissolved in austenite and an increase in the Ms and M f
