The load movement inside of a SAG mill can be monitored through the audible impacts of the falling stream of ore and grinding media with themselves and with the mill liners. The mill noise is a mixture of many different sound sources. The main source is the large number of small shocks betweenponents during tumbling of the mill load, audible as a continuous stochastic noise. An
Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size. Considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding

If one cell is mounted on a lightweight crossbeam that has a high deflection, it can sag and throw the load onto the two adjoining cells, possibly overloading them. It is a simple but critical process to shim the load cells or, if equipped, fine tune the adjusting bolts on the cell mounting hardware during installation to balance the four legs.
The SAG mill feed is controlled by the mill weight, measured by 4 load cells on the mill bearing system. Therefore if the ore does not grind quickly enough in the SAG mills, the mill weight increases and the control system reduces feed to the mill to maintain the desired mill weight.

complicated supporting of the mill shell. Load cells in the base of the bearing allow the mill weight to be recorded. Proven seals prevent dirt or splash water from entering the bearing housing. As the mill shell is a welded assembly, there are plicated and heavy end wall castings. Straight mill end walls offer the advantage that the mill liner plates have a simple shape and are quick

In an SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the balls charged were 4.1 and 7.9, respectively. The mill was rotated at 75 of its
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 load.
