The trommel gold wash plant is the equipment for sorting placer gold in mineral processing. The cylinder of the trommel screen is generally divided into several sections. The sieve holes are arranged from small to large, and the sieve holes on each section have the same diameter.
Alluvial gold mines usually are on hillsides, river beds, and lakeshores. Those large and enough to be worth mining are called placer gold deposits. The degree of monomer dissociation of placer gold ore is relatively high. You only need to use the trommel washer to screen out large pieces of waste rock that does not contain gold, and the gold ore will remain on the gold-sticking blanket to achieve the preliminary gold separation.
The raw placer gold materials are fed into the hopper through engineering vehicles. After being flushed with high-pressure water, they enter the trommel washer for screening and classification into three levels: coarse material, fine material and waste material. Due to the tilt and rotation of the drum device, the material on the screen surface flip and roll. The waste materials are directly discharged to the waste area through the conveyor; coarse materials and fine materials enter the gold-sticking blanket through the fixed chute. The degree of this equipment for placer gold refinery is high. What’s more, because of the flipping and rolling, materials stuck in the screen holes can be ejected to prevent the holes from being blocked.
