Difference Between Sag Mill vs Ball Mill mech4study

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is

SAG Molycop

The Molycop range of SAG grinding balls is prepared for impact. Through an innovative manufacturing process we’ve produced a ball with greater impact resistance and reduced spalling compared to the standard SAG ball, ready to perform in the highest impact SAG milling environments.

Autogenous and Semi-Autogenous Mills

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

SAG Mill Control: It Shouldn’t be that Hard E & MJ

2020-4-8  SAG milling is arguably the most commonly used method of comminution in mineral processing. A control strategy recently implemented on a large variable-speed SAG mill at MMG’s Century Zinc operation in Australia is shown in the chart (found on pg. 32). In this case, mill speed is the primary manipulated variable used to control mill load.

Barry Wills' Blog: Where are SAG mills going?

2021-1-15  In our recent conversation, Prof. Alban Lynch was very sceptical about where semi-autogenous grinding (SAG) mills have gone, and thinks they have taken us along the wrong track. He feels that they may be attractive in terms of high productivity, but says that "their energy efficiency is poor, and I feel that these immense machines are going to turn into very large ball mills".
