Sep 28, 2011 Anthracite Coal vs Bituminous Coal . Coal is a fossil fuel similar to natural gas and oil, which is in a solid rock form. Coal is formed by collecting plant debris in swamps. The process takes thousands of years. When plant materials collect on swamps, they degrade extremely slowly.Coal fines are usually prepared by air swept coal mill or vertical mill. In order to produce high-quality clinker, the fineness of coal fines should be controlled at about 12 , and its moisture content should be controlled within 1.0 . The machines that are usually used to dry the coal fines are rotary dryers.
Australian metallurgical coal is ideally placed, in terms of high coal quality, proximity to key markets in Asia, consistent dependability of supply (weather events aside) and infrastructure availability, to share in coal demand growth to 2030 and possibly beyond.Coal pulverizer mills are utilized in many coal fired power generation facilities across the country and around the world. These coal mills utilize centrifugal exhaust fans to induce and transport a very abrasive air and coal particulate mixture from the mill to the burner for combustion in the boiler.

The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler.
Using smaller size raw coal feed to mill to increase the milling capacity only shift the workload to the raw-coal precrusher.Normally optimum coal size is selected so that total initial, operating and maintenance cost of precrusher and mill can be kept minimum. Coal passing through 20 25 mm mesh is found suitable for Indian conditions FINENESS.The Coal Quality Course provides an understanding of the importance of managing coal quality from the exploration to mining and transportation. It also provides an overview of the end-use of coal in the cokemaking and power generation sectors and the impact of coal quality on these processes. It highlights issues of milling and handling.
The coal seam should be wide enough to ensure that coal extraction is possible without contamination by hanging wall or footwall lithology, or dilution by lower grade portions of the seam. Screening, crushing, hand-picking, and benefi-ciation maybe essential for thinner seams of high quality coal that are subject to contamination and dilution.Coal Mill Pinion.
