Gold trommel scrubber is widely used for cleaning various kinds of difficult-to-wash bulk ore, stone, sand & gravel, it is divided into cylinder type and plus screening strip type, the latter can process fine and coarse feed simultaneously, remove or classify the feeding material according to the particle size, +40mm and -40mm. The feed which size -40mm then can be divided into +2mm and -2mm ...Trommel screen mining industry ball mill. The Ball Mill Discharge Trommel Screen has wide application in practically every type of placer work, in gravel plants, and in ore-dressing. This type of screen is particularly adapted for screening at coarse sizes, or at finer sizes if spray water can be used freely without interfering with screening.The SAG mill will be a 6.10 m diameter x 3.60 m EGL mill with a 2,200 kW variable speed motor. The SAG mill will operate with 7.2% to 15.0% ball charge. Mineralized material will be fed to the SAG mill at a controlled rate, nominally 127.8 dry t/h, and sulphide process water added to the feed chute to achieve the desired milling density (70%.

Ore will be ground in water to the final product size in a SAG mill primary grinding circuit and a ball mill secondary grinding circuit. The primary grinding SAG mill will operate in closed circuit with a trammel screen, pebble wash screen, and a pebble crusher. Undersize from the trommel screen will be conveyed to the SAG mill grinding circuit.Trommel screen, or rotary screen, is a kind of mechanical screening machine which is widely used in the separation operation. It controls the material separation by the particle size, and the separation precision is high. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation.Both SAG mills are fitted with discharge grates with pebble ports to retain grinding media and larger particles while allowing smaller particles to discharge from the mill. Each SAG mill is fitted with a trommel screen to separate slurry and pebbles. Trommel oversize from each SAG mill reports to a surge bin and pebble crusher via transfer.
