    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.
