Coal Mill Per Boiler Hsbcgraduates. Dec 13 2011 a vertical spindle mill is also designed for pressurized and suction type requirements.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 two-thirds of the ball mills.

We investigated the leachability of elements from mill rejects from the high-sulfur, bituminous Upper Pennsylvanian Pittsburgh coal, using the synthetic groundwater leaching procedure (SGLP), long-term leaching (LTL), and the U.S. Environmental Protection Agency's (EPA's) toxicity characteristic leaching procedure (TCLP), and compared their leaching …

The amount of mill reject is significant in older operating plant. In India for example, it is about 0.5–1.0% 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.
