Optimizing the performance of Semi-Autogenous mills (SAG mills) is our core focus. Our mineral processing experts have been increasing throughput and reducing specific power while preventing upsets for over 30 years. We use our vast experience and specialized tools to provide SAG mill specific strategies to the worlds foremost mineral processing companies. Our strategies are the best in the business.
Operation of a SAG mill provides unique challenges. Unknown and changing process variables like ore hardness and ball charge make determining process set points difficult. By applying our world class strategies we are able to monitor your SAG mill on a second to second basis. Our KSX software can make small subtle changes regularly to locate each new optimal grinding steady state as your process variables change.
Our strategies regularly see increases in SAG mill production of 4% to 8%, and even larger gains have been documented. While throughput improvements vary depending on many variables, it is important to use your SAG mill circuit to the maximum extent possible. Don't let operator inexperience, inattention or data overload limit your production. Maintain the optimal production of your SAG mill with second by second expert responses to changes in your process. Our SAG mill strategies allow you to do accomplish this.
The following example demonstrates the financial impact of just 1% increase in throughput for a typical large Copper concentrator.
| Tons/day | Head Grade | Recovery | $/lb | Benefit/year | Payback |
| 120,000 | 0.7% | 88% | 2.80 | $17,169,600 | 10.7 days |
Even for a tenth of that improvement and half of that copper price the payback time for even an extensive project is still under a year. You can not afford not to contact us.
Our state of the art expert system software, KSX, allows us to provide our vast knowledge to your operation in a fraction of the time that others can. With KSX you get a transparent system, where you can get "under the hood" and maintain your SAG mill strategy with ease. Because KSX is a general expert system, you can easily extend advanced control beyond your SAG mill to other parts of your plant like flotation and thickening.
