SAG Mill Discharge Controlling the feed and discharge of a mill is mostly a stabilisation exercise – you need to be able to quickly and accurately control the mill feed rate If the mill feed setpoint is changed then the actual feed rate needs to stabilise at the new target in a short period of time The feed rate setpoint can then be tied

Experienced SAG mill operators are familiar with the concept that an optimal volumetric mill filling exists which maximizes the mill throughput rate of a set feed material The grind curve work of Powell and Mainza 2006 and Powell et al 2009 demonstrated that the optimal volumetric mill filling for maximum federate does not necessarily

SAG and AG mills produce more fines as a proportion of the whole particle size distribution than more classical comminution machines such as rod mills This causes a problem for powerbased models because only a single point the 80 passing point is used as a proxy to represent the whole particle size distribution and the whole
