The Standard Autogenous Grinding Design (SAGDesign) test measures macro and micro ore hardness by means of a SAG mill test and a standard Bond ball mill work index test on SAG ground ore. Ore feed is prepared from a minimum of 10 kg of split diamond drill core samples by stage crushing the ore in a jaw crusher to 80% product passing 19 mm.

The work index covering grinding in tumbling mills of coarse sizes is labelled M ia. The work index covering grinding of fine particles is labelled M ib. M ia values are provided as a standard output from a SMC Test® (Morrell, 2004a) whilst M ib values can be determined using the data generated by a conventional Bond ball mill work index test (M

The Bond Work Index figures obtained by backcalculation from the pendulum data are compared with the Net Work Index values obtained from the plants in Fig. (8). The agreement is surprisingly good especially in view of the fact that the 80% passing values do not completely describe the total feed arid product size distributions.

An impact pendulum that follows strictly Bond's standard for crushability measurement [5, 32, 33] has been used, which allows calculating the crushing, or impact, work index. The test consists of dropping two pendulum-mounted hammers simultaneously, each weighing 13.6 kg, against individual particles of size ranging from …

The Bond low-energy impact test apparatus consists of two pendulum hammers mounted on two bicycle wheels, so as to strike equal blows simultaneously on opposite sides of each rock specimen. The height of the pendulum is raised until the energy is sufficient to break the specimen (Bond, 1947), and then the crusher work index (CWI) or impact

• Autogenous Work Index or AWi is a term used to relate SAG mill Feed and Product sizes to consumed energy, using Bond equations. Its value is determined in the MacPherson Test or as an operating work index by using values from an operating circuit. Its value is only valid at the stated SAG product size.
