About Quality of Coal: Abrasion Index

Jun 05, 2013· Abrasion index is an index that shows the abrasive properties (abrasion) of coal on the part of the equipment used to grind the coal before being used as fuel in certain combustion systems. The higher the index the abrasive coal the higher the maintenance costs of the coal grinding equipment.
