About Quality of Coal: Abrasion Index

Jun 05, 2013 A coal called abrasive when his abrasive index 400-600, and referred not abrasive when his abrasive index < = 10. Coke has abrasive index in 2500 while having an abrasive sandstone index 1200. Desired coal buyers must have abrasive index < = 200. If abrasive index its > 200, the price of coal could be cheaper or perhaps is totally rejected.

An Analytical Model of Coal Abrasiveness Index in Function

the amount of abrasion is mainly determined by the magnitude of the relative hardness of materials in friction. In the case of a coal particle in friction against the YGP tester blade, abrasion of the mineral inclusion is defined as /h h i b where h i and h b respectively represent the mineral particle hardness and the blade hardness.

Assessment and prediction of coal abrasiveness ScienceDirect

Sep 01, 1990 'Inherent abrasive index' (IAI), defined as the abrasion index of the coal in an air-dry condition, was related to the ash analysis of the coal by the equation: IAI=(S+F-1.11)/0.118 (r=0.98) (1) where S and F are the mass per cent of silicon (as SiO^) and iron (as Fe^C^) respectively in the coal, at 15% Assessment and prediction of coal

An Analytical Model of Coal Abrasiveness Index in Function

Then the coal particle being a composite structure made of a variety of mineral components, its hardness is determined by applying the rule of mixture for mechanical properties of composite materials. The resulting formula shows that the coal abrasiveness index can be evaluated as a linear combination of the mass percentage of mineral components.
