IMPROVEMENTS IN SAG MILL THROUGHPUT FROM FINER FEED SIZE AT THE NEWMONT AHAFO OPERATION , Ahafo operate a SAG mill, ball mill and pebble crusher (SABC) circuit that processes a range of , control of the blasting, crushing, grinding and flotation process.
That does not mean that the preference is speed control over feed rate control Each ore is different and each plant is different As equipment designers, we have to provide each of the features that the operators could use to optimize their process In my experience, SAG Mills are normally variable speed, and Ball Mills are normally fixed speed.
We have implemented SAG and ball mill expert control solutions and thickener control in the past at cortez Below are the results from the SAG mill optimization SAG mill throughput was increased by 93% It is interesting to note that the expert control of the SAG mill alone yielded a 6% increase.
These signals along with an energy polar plot taken from the shell provide the real-time toe, material flow rate and ball strike energy occurring in the mill For cement, MillScan is the easy to calibrate electronic ear replacement for real-time mill fill level monitoring and feeder control.
Following the SAG mill will be two 9,000-hp ball mills, each one 20-ft in diam and 331/2-ft long, that do the finish grinding , PoE technology is being be applied to motion control with the.

Ball mill process control Predictive Control which drive the process to higher levels of performance and for much longer sustained periods Model Predictive Control for SAG and Ball Mill Control Real Time Optimization based on a model predictive controller is considered a better approach to SAG and ball mill control Live Chat.
Oct 12, 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 piec 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 filled with balls partially.
The Manta Cube ® system can be used to control various processing units and has been successfully used for SAG Mill Control, Ball Mill Control, Flotation Control, Thickener Control, CCD Control.
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 highest throughput, reliability.
SAG mill coming out of a classical overload) These examples highlight a fundamental difference between ball mill and SAG mill control While monitoring power draw alone is sufficient for ball mills, in SAG mills, both bearing pressure and power draw need to be considered for proper operation and control.
Nov 26, Difference Between SAG Mill and Ball Mill, from the working principle, application, structure, etc Grind and blend solid or hard materials into smaller pieces by means of.
Rely on our proven track record of SAG and AG Mill superiority Since the early s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.
