purposes, SAG mills utilise a combination of steel balls and coarse ore to achieve the desired discharge particle size [2]. An essential performance metric for a SAG mill is its throughput, which measures the volume of processed ore per hour [3]. SAG mill throughput maximisation stands as a critical priority, given its profound financial outcomes.

Conditions inside your mill are automatically adjusted to minimise liner damage, stabilise and then optimise the operation of a SAG Mill. With the combination of ECS/ProcessExpert and LoadIQ, your mill will grind more efficiently, helping to reduce energy consumption while lifting throughput and extending the life of your mill liners and ...

The SAG mill had a 6–8% ball charge and the power consumption was 8 kWh/t, which agreed well with the expected value. 9.6. Problems. 9.1. 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.

Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the …

(EGL) SAG mill driven by a 24,000 kW gearless drive. The SAG mill feeds two FL ball mills each 26 ft. in diameter × 40 ft. long (EGL), each driven by a 16,400 kW drive. The SAG mill is one of the largest volumetric capacity SAG mills in the world and represented the first 40 ft. SAG mill in Peru (Garcia & Villanueva, 2013 [1]).

With alternative grinding options providing a means to decrease energy and water use, North American Mining asked a group of leading experts for their opinion of the …

A linkedin.com group was recently discussing this by asking: I've tried to estimate AG/SAG Mill power requirements using several different methods: (1) Using the results of SMC data (2) Using SAG Power Index (SPI) data (3) Using the 1989 Barratt method updated on Alex Doll's Web site (February 16, 2015)

SAG mills are distinguished by utilising run-of-mine (RoM) feed as grinding media with 5 – 18% steel balls added to supplement grinding media. In recent years, RoM Ball mills have started taking ...

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 ...

The first example of using an agitated vessel and grinding media for comminution was in 1922 when Szegvari stirred a gallon can full of pebbles to rapidly disperse a sulphur suspension [19].This was developed into the first 'stirred ball mill' by Klein and Szegvari in 1928 [20].This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s [21]) …

The screen oversize is returned to the primary mill feed. This allows the operator to see and measure the plus 13 mm circulating load of critical size material. If the secondary mill is a pebble mill, grinding media for the pebble mill may be removed from the top deck of the screen with any excess returned to the primary mill.

The SAG mill was sized with 746 kW to give a 25% contingency for power swings on the calculated power. The ball mill was sized at 1120 kW. Total installed power for comminution exceeded that required for conventional grinding by a factor of 1.163 (including secondary crushing).
