An Analytical Model of Coal Abrasiveness Index in

2015-3-4  the characterization of the abrasiveness index (AI) for coal used in the South African power generation industry became a cause for concern due to lack of standardization of test results. The standardization of abrasiveness test results requires good understanding of determining factors and the availability of reliable technological mean to ensure a control thereof. Reported works in the literature show that many factors determine the abrasiveness of coal. These factors include material own characteristics as well as factors related to the test method. The properties of coal particle that affect its abrasiveness mainly include the particle hardness, the grain size, the grain shape, the material toughness, the mineral composition, the concentration, and the degree of inclusion [1-5]. Parameters related to the test method like contact pressure, sliding velocity, blade hardness also affect the abrasiveness

Assessment and prediction of coal abrasiveness -

1990-9-1  '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 abrasiveness: C.
