composition of coal crushing balls

Coal ball Wikipedia

A coal ball is a type of concretion, varying in shape from an imperfect sphere to a flat-lying, irregular slab.Coal balls were formed in Carboniferous Period swamps and mires, when peat was prevented from being turned into coal by the high amount of calcite surrounding the peat; the calcite caused it to be turned into stone instead. As such, despite not actually being made of coal, the coal

Liberation properties of middling coking coal under shear

Sep 01, 2017· The low-ash clean coal release rate, L a, and fine coal index, L b, after crushing were proposed as measures for determining the degree of liberation and selective crushing of middling coking coal. The results indicated that a low shear angle increased the low-ash clean coal release rate, but a high shear angle decreased the production of fines

Coal Structure and properties of coal Britannica

Coal Coal Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and

Coal Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

CONTRIBUTION TO DETERMINATION OF COAL

in coal increases the HGI value, whereas the micronite and liptinite macerals decrease the grindability (Hsieh, 1976; Hower, 1987). On the basis of research of black coal from Kentucky Hower and Wild (1988) have derived that part of the HGI change can be explained by maceral composition, mainly by liptinite contents, which is the most

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
