Mill speed can be adapted to upstream and downstream processes – avoids overgrinding, and optimizes load distribution between SAG and ball mill (Mular, Halbe & Barratt, 2002). Power consumption is influenced by load respectively torque and mill speed. This means that further energy can be saved if a mill speed below the rate speed is re-

SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range. Typically a SAG mill weight measurement, by either bearing pressure transducers or load cells, is used as an inferred measurement of volumetric filling. To maintain volumetric filling within a set operating range the SAG weight setpoint use for process control …

The company selected ABB's 26 MW gearless mill drive system (GMD) for the mine's 40 ft SAG mill, as well as other drives, electrical infrastructure equipment and a long-term service agreement (LTSA). This is expected to reduce operating costs, improve process throughput and reliability while saving energy and keep equipment in top form.

Rocky DEM, a software tool developed by Brazilian company Engineering Simulation and Scientific Software (ESSS), predicts SAG mill liner wear over time and helps engineers adjust conditions for mill operations by easily assessing change-of-process variables such as speed and fill level.

SAG Mill Design and Specification . The Kidston plant was designed to process 7500 tpd fresh ore of average hardness; but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. Some of the equipment, therefore, will become ...

As long as the amount of bar sag is known and is consistent, it can be compensated for during the alignment process. Quantifying the sag. During each alignment task, after the indicator(s) have been set up on the machine, it is necessary to determine how much bar sag exists. To determine the amount of sag, the fixtures must be taken off the ...

SAG Mill Liner Design In summary: A broad range of AG/SAG circuit configurations are in operation. Very large line plants have been designed, constructed, and operated. The circuits have demonstrated reliability, high overall availabilities, streamlined maintenance shutdowns, and efficient operation.

Elastic mill sag by weight of mill balls and materia! to grind A: After temporary alignment of the teeth of pinion and girth gear with the mill empty, Fig. 8a, re-alignment should be undertaken with the mill filled with mill balls, i. e. with reference to the elastic sag in cold con- dition, Fig. 8b.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
