DWi and point load index (IS50) making it valuable in Mine-to-mill studies as well. For power-based calculations the SMC Test also provides the comminution indices Mia, Mih and Mic,which are routinely reported when a test is carried out (see Table 1 below). In conjunction with the Bond ball mill work index they can be used to

Mill diameter; Mineral density; Work Index. Bond estimated the amount of wear in terms of kilograms per kWh based on the abrasion index, A;, i.e., Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33; Dry Ball Mill = kg / kWh = 0.023A i 0.5; Replacement Ball Size

Specifically, the Bond work index is suitable for utili-zation in many industrial grinding processes with particle sizes ranging from 1 mm to 1 μm (Rhodes, 1998).
