Trommel screens, also known as trommels or rotary screens. They are broadly applied in the discharge ends of AG mills, SAG mills and ball mills to classify materials. They are a success in mineral processing plants of non-ferrous metals mines.
Nov 19, 2019 SAG mill trommel screen mechanism classifies large volumes of 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.
Multotec has supplied a number of trommel screens for 38-40-ft 11.6-12.2 m SAG mills that required 500-600 mm high weir bars to create sufficient retention time. It can also supply a range of rubber shell plates and lifter bars to protect the SAG mill trunnion against wear.
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 flowsheet for line 2 with only the trommel,
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.
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 58 or 16mm In the image case below strangely enough Metso is the mill shell liner and discharge grate manufacturer
SAG Mill Vibrating Screen Deck By placing a magnetic drum over a vibrating screen Figure 9, an installation will realize a ... Figures 11 and 12 indicate how a trommel screen is replaced by a trunnion magnet system. The trunnion magnet is mounted at the ball mill discharge point.
The company said it has supplied trommel screens for almost four decades and has the capability to size SAG mill trommel screens with diameters up to 5.5 m. It designs the trommel screens to suit each customers unique requirements, with capacities ranging up to more than 3,500 tons per hour th solids.
The SAG Mill was designed with 13.4 MW of installed power for size reduction from a 175mm feed size down to 2 mm -10 mm of product size with given maximum ball charge of 13 by volumea using 127 mm diameter grinding media. The aperture of the SAG Trommel Screen was 10 mm x 25 mm providing a 25 pebble circulating load.

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 SAGAG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
Trommel screen s are often included as a classifica tion stage at the discharge end of AG, SAG and ball mills to ensure correct sizing of prod uct from the mill and t o separate out oversize ...
The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen 5, which acts like a large sieve.
Tumbling mill AG, SAG, rod, and ball mills discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AGSAG mills, to
Multotec has supplied a number of trommel screens for 38 to 40-foot SAG mills that required 500 to 600 mm high weir bars to create sufficient retention time. It can also supply a range of rubber shell plates and lifter bars to protect the SAG mill trunnion against wear.
