Fig 1 Types of coal and their uses. The term ''coking coal'' is used to designate certain types of bituminous coals which, when heated at high temperatures (over 1,000 deg C) in the absence of air (carbonization), soften, liquefy, and then resolidify into a hard but porous mass known as coke, used mainly in the production of hot metal in a blast furnace.
Therefore, the probability of contact between an abrasive particle and the YGP blades is proportional to the volume concentration of the abrasive constituents in the coal. The volume abrasion index (VAI) of the coal, expressed as the g metal loss per m3 of coal, is equivalent to AI x By/1000. 20 40 G0 80 MINERRL MRTTER CONTENT.

Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined ...
Wilfrid Francis, Martin C. Peters, in Fuels and Fuel Technology (Second Edition), 1980. E Storage. The swelling index of coal falls rapidly with lowtemperature oxidation, by storing finely ground coal. The quality of coke produced from the weakly caking coals of North Staffs. South Yorkshire and Lancashire is greatly reduced by storing the coal for a few days after preparation.
