In the mining sector these losses can be quite substantial. For example a trained professional crew may require up to 120 hours to replace the worn liner of a SAG mill with each hour costing tens or even hundreds of thousands of dollars depending on the size of the mill and the plant in which it operates.
grinding mill and AGSAG mills. MILL MONITOR SYSTEM AND RECENT ENHANCEMENTS. The key features of the original prototype of a ruggedized continuous mill monitoring system were described in Campbell . et al 2006. A number of changes have subsequently been made to the various components of the mill monitor during evaluation of the prototype system.
Whether youre talking about SAG or a ball mill space is a delicate issue especially in the concentrator. Thats why we always design our Gearless mill drives drives to combine maximum performance with limited space requirements. Suitable foundation and adequate ground conditions Since our solutions have a low motor weight this notice-
The mill charge volume has a great impact on grinding efficiency. For efficient grinding autogenous AG and semi-autogenous SAG mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indication of the mill charge volume.

The working principle of the SAG mill and AG mill is basically the same as the ball mill machine but the barrel diameter of the SAG mill and AG mill is larger. The raw ore enters the AG mill through the feeding inlet and the material is brought to a high place under the rotation of the barrel and then falls.
Mar 13 2018018332Stopping mill equipment is not a desirable alternative so the best way to resolve SAG mill challenges is to use simulation technology for equipment design alterations. Replacing the SAGs worn-out liner can occur every six to nine months and cost between 30000 U.S. and 200000 U.S. per hour and each repair takes between 40 hours and 120 .
Principle of SAG Mill operation. SAG is an acronym for semi-autogenous grinding. 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. SAG mills use a ball charge of 8 to 21. 6 7 The largest SAG mill is 42 12.8m in diameter powered by a 28 MW 38000 HP .
The even wear allows for the new life potential of media rejected from ported SAG mills. The rejects are totally recyclable since the media retains their integrity for ongoing deployment in a secondary mill. Recycling to a ball mill as supplementary media or possibly as resale to other users provides additional value for our clients.
