    Bond Work Index - an overview | ScienceDirect Topics

    The Hardgrove index is determined using the ASTM method D 409–71. It involves grinding 50g of the material, e.g. coal, of specified size (16–30 mesh cut) in a specified ball-and-race mill for 60 revolutions. The amount of 200 mesh material is measured ( w grams) and the index is defined as I= 13 + 6.93 w.
