in tonnage or SAG mill feed density are returned to the DCS PID controllers Fuzzy sets are defined for all the measured parameters Each attribute is normalised, and its span divided into fuzzy belief valu A typical example is the SAG Mill 1 Bearing pressure (described later in Figure 3) These fuzzy belief values are used as inputs to 80...
H l -controller design for SAG millThe first step in the design of a robust controller for the SAG mill involves obtaining linear dynamic models (expressed as transfer functions) for the impact of the manipulated variable (ie feed flowrate) and the disturbance (ie the F 80 parameter) on the variable to be controlled (ie the SAG mill power ....
concentrator site in order to tightly control the weight in the SAG mill to promote optimum grinding This stra-tegy has improved mill throughput by 59%, reduced feed variability by 56%, and reduced energy consumption per tonne by 54% Once BrainWave was installed, the improvement was...
This allowed them to reduce the SAG mill media size and operate at a slower speed without the rock load building and destabilising the mill In turn, this provided spare mill capacity which can be used to assist the ball mill One of SRK’s recommendations under consideration is returning a portion of the cyclone underflow back to the SAG mill...
Jan 01, 2009· SAG Mill Control Strategy using Profit Controller "ProfitSAG" applications have been implemented using Honeywell technology called "Profit ControllerTM"; this is a Multivariable Predictive Control algorithm based on models, also known as RMPCT (Robust Multivariable Predictive Control Technology) As its name points out, this controller SAG 1 ....
Jun 06, 2016· By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006) A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the ....
