In coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system. Coal Mill in Power Plant,Working Principle of Ball Mill General use of coal powder particles diameter range of 0-1000 um, mostly 20-50 um particles, so the coal powder to make coal mill has certain requirements. Coal grinding mill is a machine that crushes and grinds coal into pulverized coal. It is an important auxiliary equipment of pulverized coal furnace. The ball mill is a horizontal cylindrical rotating device driven by external gears. Mate rial from the feed device enters the mill evenly through the feed hollow shaft helix. 2020-3-6 Coal mill is mainly composed of feeding device, main bearing, rotating part, pulverized coal burner, discharging device, high-pressure starting device and lubrication system.
