additional crushing stages for increasing the throughput of existing SAG mill circuits [5]. In the case of such modification, the SAG mill product is coarser compared with the corresponding relatively coarse feed size distribution, thus resulting in a higher energy requirement for ball milling in SABSemiautogenous ball mill circuits.

The power draw increases as balls are added and decreases as media wears down: add balls. The main control on the power draw for a BM is the load of grinding media however adding water to the cyclone underflow can also be short term control of BM power. Higher ball loads will result in finer grind but don't overcharge.

However, stickiness can also increase with higher fineness. Material with high stickiness creates problems in all aspects of the grinding process, including feeding (, making metering into the mill difficult), grinding (, plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (, plugging the

Hard ore Work Index 16 = 100,000/65,000 = kwh/t For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of kw/t reduces the ball mill feed size to 6,500 micrometers.

As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw.

To increase or decrease capacity while operating at the same pressure, look to change the size of the inlet area. Takeaway: Larger inlet sizes allow for a higher capacity, while smaller inlet sizes allow for a smaller capacity. 4. Vortex finder diameter. Similar to the inlet area, the vortex finder diameter can affect capacity and the cut point.
