• Laboratory methods for combined testing of abrasiveness ...

    traditional method for coal is based on the procedure given by Yancey, Geer, and Price [] and described more fully in British St andard [] as the Index of Abrasion (AI). Each of these indices measures a given property of the coal, but the wear in a mill is a composite of these two separate factors, since the easier it is to crush

  • A Word for the Coal Miner

    Abrasion Index Indicates the abrasiveness of coal by monitoring the loss in weight of four metal blades which mechanically stir a sample of sized coal.The index is the number of milligrams of metal abraded from the metal blades per kg of coal used. Based on a test known as the Yancey, Geer and Price test.
