This washer will prepare coal in five sizes. No. 1, 3 x 2 inches, and No. 2, 2 x 1¼ inches, are mainly intended for domestic use, where the demand is big, but it has also been found that, owing to the quality of the coal, the No. 2 will work very well in brick yards; as a consequence, part of that product goes to that use. No. 3, 1¼ x ¾ ...
Constructed at the base of the mountain were a series of "beehive" ovens, designed to turn coal into coke for use in the iron and steel foundries of nearby Chattanooga. The first 24 ovens and the company store were built in 1902. In 1906, 144 ovens and a steam powered coal washer were constructed.
Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically altered, and

Coal Preparation Plant: It is proposed to instal a second-hand jig-type washing plant to supplement the existing coal screening and crushing plant. The modified coal preparation plant would then produce washed coal of two sizes: 'nut' coal (plus 19mm to plus 6mm size) and washed fine coal (minus 50mm in size).
refuse material from coal sizes smaller than 2.5 inches.) After exiting the washer, the coal fell onto two 50-foot shaker screens for sizing. Coal sizes smaller than 3/8-inch was rewashed and then entered centrifugal dryers. Sludge from the dryers went into an 85-foot wide Dorr thickener and then to a filter that removed 60% of the moisture.

It can be concluded that a pile packed with smaller coal particles is more likely to undergo spontaneous combustion, while the chemical activation energy is not sensitive to coal particle size. Finally, the effect of coal particle size on T ...
Washability characteristics of the raw coals should be the prime criteria in selecting the washing circuit. Considering the poor liberation characteristics, high ash Indian non-coking coals should preferably be washed at larger size i.e. at –100mm size. The washed coal can be crushed to finer size, if desired.
