a.1. 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 (i.e. feed flowrate) and the disturbance (i.e. the f 80 parameter) on the variable to be controlled (i.e. the sag mill,model predictive control for an industrial sag mill,we use an industrial semi-autogenous grinding (sag) mill to illustrate the performance of this controller. sag mills are the primary units in a grinding chain and also the most power consuming units. therefore, improved control of sag mills has the potential to signicantly improve eciency and reduce the specic energy consumption for mineral

the process state of an ag/sag mill can be inferred from surface vibration monitoring. this is a passive, non-intrusive, low cost and reliable hardware monitoring technology that is sensitive to,brainwave: control solutions for sag mills,brainwave sag mill is a unique control package using patented model-based predictive adaptive control technology. it is well known within the mining industry that effective grinding in a sag mill depends largely on the loading of the mill. a mill con - taining too much material does not allow for adequate movement of the ore and balls within
details of the complete sag mill package . the sag mill has a mill diameter of 24 feet and an effective grinding length ('egl) of 18.5 feet and a structural charge mass of 315 metric tonnes. the structural design ball charge is 11% with a structural design load,dynamic modeling and simulation of sag mill circuits with,grinding is one of the most energy-consuming processes in the mining industry. as a critical part of the comminution process, autogenous grinding (ag) or semi-autogenous grinding (sag) mills are often used for primary grinding. however, the breakage mechanism of an ag/sag mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles.
