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 containing too much material does not allow for adequate movement of the ore and balls within the.
Control stabilization for sag mills brainwave is ideally suited to stabilize the operation of sag mills. effective grinding in a sag mill depends largely on how it is loaded. a mill containing too much material does not allow for adequate movement of the ore and.
Following a successful commissioning and start-up, we believe that two grinding lines at las bambas, per , each consisting of one sag mill and one ball mill (this mill combination is uniquely specific to las bambas ore types), are operating at design throughput of close to 140,000 tpd and within the range predicted by djb from a managed multi-sample geometallurgical testing program (i.e., no.

The best way to measure load is to mount the mill on load cells. the load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill, but not the weight of the mill itself. while many mills today are mounted on load cells, others employ bearing oil pressure as a proxy measurement of mill.
Today, autogenous grinding (ag) mills as large as 40-ft in diameter with motor power in excess of 20 mw are being ordered and installed as producers look for higher production and economy of scale in their process plants. semiautogenous grinding (sag) mills up to 44-ft diameter with 35-mw gearless mill drives (gmds) are.
