alluvial sand gravel ore wash plant gold trommel screen
Machine description:
A placer gold trommel screen is a piece of mining equipment that is quite popular and is used all around the world on all different sized mining operations. Their purpose is to process gold bearing material by separating out the larger rocks and boulders, allowing the smaller material that contains the gold to be run through a sluice box.
Depending on the quality of the trommel and the type of material that you are feeding into it, a grizzly may also be used prior to feeding the trommel in order to separate out the largest boulders. This will allow the system to operate at its optimum potential. Some larger wash plants have grizzlies set up directly over the hopper when the material is added.
Features of placer gold trommel screen
Placer gold trommel screens are very efficient gold grabbers and even extremely fine or flour gold in the micron range can be recovered consistently using a properly constructed trommel that is set up for peak operation. Additionally, like a highbanker, trommels can be set up anywhere near the source of auriferous material, as long as water can be pumped or "fed" into the drum unit and there is a power source to operate the unit.
How the trommels work
1) The placer gold trommel screen is first set up at or near the auriferous material to be processed.
2) It is then energized, the motor begins turning the rotating drum, and the water sprayer is activated.
3) Material is fed into the hopper box and directed into the angled and constantly turning drum.
4) The sprayer then washes or "cleans" dirt and mud from the material as it tumbles round and round inside the drum.
5) Any pieces of material (rocks and gravel) larger than the drum screen hole size will eventually be forced down the drum into the tailings tray and out, forming a tailings (coarse tailings) pile at the bottom of the unit.
6) The remainder of the gold-bearing gravel will fall into the sluice box below, where hydraulic action traps the black sands and gold while allowing the remaining waste to flow out the lower end of the box into additional tailings (fine tailings).
7) The entire process is repeated until the sluice box requires "cleaning."
8) The trommel is then shut down and all the black sand concentrates and gold are flushed from the sluice box into a container/tank.
9) The concentrates are then panned or run through a shaker table, and the gold recovered.
