Nov 13, 2016· There are many types of coal, including anthracite, bituminous, subbituminous, and lignite. Anthracite is the highest ranked, hardest, oldest, and least common type of coal. It possesses a high energy content, high percentage of carbon (>85%) and relatively little moisture or volatiles.
There are four main types of coal, and each type has different uses. Anthracite, the rarest and most mature coal, accounts for only about 1 percent of the world's total coal reserves. Because it is the most mature coal, anthracite has the highest carbon content compared to lignite,...

Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution. Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.
Coal classification There are many compositional differences between the coals mined from the different coal deposits worldwide. The different types of coal are most usually classified by rank which depends upon the degree of transformation from the original source (, decayed plants) and is therefore a measure of a coal's age.
Coal is formed as part of a very long process. Younger coal or coal where the process has been slower is different from ancient coal. Generally the older it is, the cleaner it burns. Some types are: lignite, subbituminous coal, anthracite, and bituminous coal
Garnet, epidote, pyroxene, and apatite are found in the wall rock as well as in the ore. The magnetite deposits of the islands along the Pacific coast, British Columbia, are of this type, as are also many of those of southeastern Ontario and the adjoining part of Quebec, notably the Marmora and Bristol mines.
Classification of coal based on volatile matter and cooking power of clean material. Bituminous coal ignites easily and burns long with a relatively long flame. If improperly fired bituminous coal is characterized with excess smoke and soot. Anthracite coal is the last classification, the ultimate maturation. Anthracite coal is very hard and shiny.

Coal Grades The gradation of noncoking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification.
Types of Crushers. Crushers may be divided into three general classes, with respect to the manner in which they do their work: Pressure Crushers: This category embraces the several types of gyratory crushers and jaw crushers, as well as the double crushing rolls, with either smooth or corrugated shells.
