Applications

Designed to recover gold and other heavy minerals from placer deposits. Ideal for sampling placer deposits for evaluation of mineral content or for processing small high-grade placers for recovery of gold, tin, tungsten, or other heavy minerals.

Principle of Operation

Feed up to 3″ in size is either manually shoveled into the hopper or fed by conveyor at a rate of 2 to 3 cubic yards per hour. Water is added to help disintegrate clay and wash the values off of the oversize material in the trommel section. Lifter bars are provided to assist in breaking down clay.

The oversize fraction is discharged from the trommel. An internal ring at the end of the trommel serves as a “nugget trap”.
The approximately minus 3/16-inch material passes through the trammel screen and is sluiced and conveyed by flights positioned on the inside of the outer trommel as feed to the shaking riffle. The feed material cascades over the multi-stage riffle. A lateral shaking action keeps the bed of sand in the riffle alive and permits the heavier minerals, both coarse and fine, to be trapped in the riffle pockets. Riffle pan is suspended from rubber sheathed cables to eliminate noise and wear. The slope of the riffle pan is adjustable to alter the retention time of the sands in the riffle bed. Periodically, the riffle is removed to empty the heavy values and the feed cycle is repeated. Tailings flow down the riffle and out the discharge chute by gravity
