of the SAG mill is transferred onto a vibrating screen. The oversize material is crushed in a pebble crusher, and the undersize is combined with the ball mill (6.719.91 m) discharge and sent to the cyclones. The SAG mill in phase 1 uses two 4100 kW synchronous motors and works with a constant 10.5 rpm rotational speed in two
Feb 20, 2021Too many grinding balls can prematurely wear out the grinding balls themselves. Operating a mine mill requires balancing a dynamic set of tradeoffs. Each of these tradeoffs will impact the overall operating conditions of the comminution circuit, which means that every other variable now faces a new set of conditions to be optimized against.
ABB's GMD is the most powerful mill drive system in the market to power semiautogenous (SAG), ball and autogenous (AG) mills, This 'workhorse' for grinding operations combines a robust, service-friendly and fit for purpose design to provide
SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills.
SAG Mill Discharge. Controlling the feed and discharge of a mill is mostly a stabilisation exercise – you need to be able to quickly and accurately control the mill feed rate. If the mill feed setpoint is changed, then the actual feed rate needs to stabilise at the new target in a short period of time. The feed rate setpoint can then be tied

One of three SAG mills with 9.75 m diameter and 2 x 4000 kW drive power. These mills operate in conjunction with ball mills for iron ore grinding in Iran.
For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding
Acoustic emissions monitoring of SAG mill performance
Jul 15, 1999Abstract: Particle grinding is a final stage in the comminution process used to liberate minerals from gangue in mineral processing plants. Semi-autogenous grinding (SAG) occurs in tumbling mills which use both large ore particles and steel balls for grinding. Grinding is the most energy intensive mineral processing unit operation and hence its optimisation is of considerable interest to
