Operation Analysis Of A Sag Mill Under Diffesale

As one of the machines widely used in mining, a semi-autogenous grinding mill can significantly improve the roughing efficiency of rock. but the sag mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a sag mill, in this paper, the discrete element method is used to simulate the figure high fidelity simulation snapshot of dem ball and particle motion in an entire sag mill. this high fidelity full mill simulation has permitted prediction of motion of balls and particles, mapping of power draw, impact energy dissipation and shear work done by balls and particles on the liners as a function of distance down the mill

Throughput Optimisation In Milling Circuits

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 producing operation in the world and the sag mill at the laguna seca plant grinds approximately half of the mines sulphide ore. although plant staff was reasonably satisfied by the performance of an expert system that was controlling their mill, they suspected that improvement was still pos sible. they decided to try brainwave sag mill.
