Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages. Lower lifetime cost Simpler process requires lower capital and maintenance costs. Versatile applications Wide range of mill sizes available.

Apr 18, 2018 The obvious solution is to use more pinions, say, four per mill, with each pair coupled to the output shafts of a special single-input/double-output reducer — two reducers and two motors per mill. The problems of load division remain in this case, both in the reducers and in the motors. Another solution is to use the so-called “gearless drive.”

The distributed I/O system with IP67 modules allows for the majority of mill instrumentation to be wired up to the I/O modules and tested at the factory, enabling problem-free commissioning. Installation time and cost are also reduced as the majority of site cabling is limited to a single network and power supply cable per instrument group.

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.

It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K Ï b LD 2.5 where k is a proportionality constant.
