Feb 25, 2005 The Yancey, Geer and Price YGP abrasion index has been used for many years to assess the abrasive nature of a coal. The index is clearly related to the mineral matter in the coal, but a direct correlation with the ash content is poor. A better correlation is achieved by relating the wear of coal grinding mills and pf pipe work to the quartz and pyrite contents of the
Abrasiveness index of South African coal samples are identified using YGP method. This is done by placing 4kg of coal sample in a mill and mechanically rotating the sample with a steel blade of a certain mass and shape that stir up the sample during rotation.
Sep 10, 2009 Coal grind ability index HGI YGP indicates the ease for grinding coal.. The bigger of grind ability index, the easier to be grinded. Hardgrove Grindability Indices indicate that how hard the the coal is. The variation of HGI of each zone of 40 -60 means that the grindability is poor. Measurement of abrasivity Yancey, Gear and Price method - YGP is carried out on a

Sub bituminous coal has a heating value between 8300 and 13000 British Thermal Units per pound on a mineral-matter-free basis. On the basis of heating value, it is subdivided into sub bituminous A, sub bituminous B, and sub bituminous C ranks. Bituminous. Bituminous is the most abundant rank of coal.
