The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product.. Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 5 000 tph of solids make trommels the preferred equipment for this application.
Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally.
Trommel Screen. A trommel is a slightly inclined rotating cylindrical screen. The material is fed at one end of the cylinder and the undersize material falls through the screening surface while the oversize is conveyed by the rotating motion down the incline to the discharge end. Although trommels are relatively cheap, they have lower ...
energy required to operate large grinding mills, such as ball and rod mills, AG and SAG mills [5]. The influence of feed size on mill performance naturally follows from the fact that a considerable part of the grinding media (especially in autogenous mills) derives from the feed ore. Any change in the

In a typical grinding mill application, the grinding media eventually fractures and wears into a fine metallic powder because of the heavy re-circulating load in the mill. Energy is unnecessarily wasted to mill the milling media. As shown in Figure 3, the trunnion magnet is mounted at the ball mill discharge point to replace a trommel screen.
2.1 SAG mill modeling In MODSIM, one of the simulation models used for a SAG mill unit is SAGT (Semi-Autogenous Grinding with Trommel) model. In this model, a SAG mill with a trommel screen at mill discharge is modeled using the full population balance including particle attrition and wear (King 2001b). In this
