In coal milling for power stations, a 'closedloop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the recirculation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of recirculation loops within a mill system. The situation is ...

· Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only twothirds of the ball mills. However if the primary air fan power is also taken into account, in the case of a pressurized mill the power consumption is lower only by about 15% ...

· A major waste in a pulverized coal fired power plant is the reject produced from pulverizing mills. When coal is ground in a bowl mill heavy mineral matters are separated, but they still contain a small amount of coal mixed. However, the heating value of the rejects is generally too low for combustion in conventional boilers. As a result they find limited commercial use and are dumped in the ...

· The amount of mill reject is significant in older operating plant. In India for example, it is about –% of coal throughput into the boiler. In this paper, an exercise is undertaken to show how these rejects could be burnt to produce low pressure process steam, which could save the bleeding of main steam of the power plant and thereby augment power generation. A subcompact novel ...
