Four vibrating feeders deliver the ore to the SAG Mill feed belt. SAG Mill discharge is pumped to a primary cyclone(s). Underflow from this cyclone is recycled by gravity to the SAG mill feed while the overflow is SAG product, which is transferred to the Ball Mill. A cluster of 415" diameter, secondary cyclones classify the SAG ground

SAG Mills use a combo of ball milling and autogenous (letting the material crush itself) milling. They do have balls in them, but usually less of a load of them (820% load) than a ball mill (typically around 30% loaded). They also have plates on the inside that lift the load up and tumble it, like a dryer does.

Transfer Size, T80: Is the 80% passing size of ore as it passes from the SAG mill to the ball mill. It is typically about 1/3 the size of the screen opening but can be coarser than 1/3, especially when a pebble crusher is used. Screening at 5 mm ensures that the T80 will be about 10 mesh ( mm) ensuring that the ball mill will work efficiently.

Ball mills in HPGRBall mill circuits tend to have more installed capacity than their counterparts in AG/SAGBall mill circuits. This is because the product size distribution from AG/SAG mills tends to have more fine material than the HPGR circuit product ( Morrell, 2009, Morrell, S., 2011 ) and hence need less ball mill power.
