Jun 06, 2016 By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling while convenient, this has the ...
advantages that appeal to SAG mill operators They eliminate the need for a higher cost trommel screen and its associated maintenance. They increase mill throughput up to 5 percent and many installations increase their mill work index through more efficient grinding. These advantages translate to significant savings in a yearly basis.

Jan 10, 2021 The SAG mill was equipped with slotted grates and a 5/8 trommel screen. This allowed coarse material to pass through the screen to the ball mill circuit and also resulted in a significant tonnage of scats being rejected to the floor. The SAG mill was also found to be running at less than 50% of critical speed and physical
Aug 06, 2013 SAG Mill Trommel Screen. A SAG Mill trommel screen lets you control the true discharge size of your SAG mill or the transfer size to the downstream Ball Mill circuit. A well sized trommel should not let rocks pass to the Ball Mill if they are to be more than say 5/8 or 16mm. In the image case below, strangely enough, Metso is the mill shell liner and discharge
SAG Mill Trommel Screen provides simple mechanism to classify large volumes of mill product . The global mining industry has become more discerning about equipment selection for process plant applications, driven by the need to increase throughput and reduce downtime. The SAG mill trommel is one example that delivers on both fronts. With large volume capabilities and a
Nov 11, 2019 With mining companies looking to improve productivity and reduce downtime in the process plant, Multotec is promoting the use of its locally manufactured SAG mill trommel screens as a viable alternative to vibrating screens in SAG mill scalping applications. Many designers and mill operators believe that the benefits of simplicity and the ability to handle
Ive got to explain this a little bit. This flowsheet is typical of lines 1 and 3. The SAG mill has a trommel on the discharge end of it. Oversize is returned to the mill by a bucket wheel and water jet. Trommel undersize was pumped to a vibrating screen where the screen oversize was sent back to the mill and the undersize was pumped to the cyclone circuit. Figure 2 shows the

controlled speed variation of the mill. Product from the SAG mill passes through internal grates onto a trommel screen which scalps 7mm material and returns it to the SAG mill feed con- veyor. Trommel undersize is pumped to two parallel overflow ball mills in closed circuit with cyclones. The ANI-Ruwolt ball mills
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

Apr 29, 2021 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.
A coupled slurry-media model of mill discharge and trommel flow is developed. Fluid slurry in the mill lowers charge shoulder and toe due to drag forces. Trunnion spiral effectively returns balls back to the grinding chamber. Trommel baffles improve screening characteristics. DEM SPH can help improve mill discharge performance and trommel ...
