An SABC circuit consists of a semi-autogenous grinding (SAG) mill, ball mill, and crusher. A ball mill is a slightly inclined, horizontal rotating cylinder, partially filled with ceramic balls, flint pebbles or stainless steel balls, that grinds material to the necessary fineness by friction and impact with tumbling balls (Fig. 2).

Comminution. Comminution till is defined as a 'very dense till that appears to have been formed by abrasion of bedrock and the crushing of detritus dragged along underneath the ice, accompanied by a mixing process that results in the incorporation of rock powder produced by abrasion at the till–rock interface into the overlying glacial load' (Elson, 1988).

Otherwise the HPGR will produce pancakes (bogged up). The CADIA East Project (Newcrest mining in Australia, 2011) introduced a secondary crushing (cone crushers) followed by tertiary crusher HPGR in front of the incumbent SAG Mill This increased throughput from 17 Mtpa to over 23 Mtpa. The secondary crush product feed 65mm to HPGR crusher.

HPGR can replace the tertiary crushers or, as a pre-grinding stage, provide feeds for ball mills [,, ]. In an HPGR, energy consumption for a particle size reduction is based on the existing pressure between the floating roll (the moveable roll) and the fixed roll in the frame. This pressure can be varied from 5 to 18 MPa.

The parameter M i takes on different values depending on the comminution machine: M ia for primary tumbling mills (AG/SAG mills) that applies above 750 μm; M ib for secondary tumbling mills (e.g., ball mills) that applies below 750 μm; M ic for conventional crushers; and M ih for HPGRs. The values for M ia, M ic, and M ih were developed using the SMC Test® combined …

The HPGR-ball mill circuit was estimated to require 75% of the energy of a standard Semi-Autogenous Grinding (SAG) mill circuit. Even with an anticipated greater capital cost, the HPGR-ball mill circuit was found to give significantly better financial returns in all cases investigated in the feasibility study (Ballantyne et al., 2016).
