Work Flow for Hydraulic Vibrating Screen

Each machine is a complete portable plant, there is no need for additional screens or sluice boxes.

At the top is an extremely heavy duty grizzly bar section that will take up to 24 inch rocks ( ca. 610mm). Classification begins when the material is placed on the grizzly bars, and high-pressure water separates the sub-1'' (25.4mm) material from the large rocks. Then the screen deck further classifies the material, and sub-.25 (6.35mm) material drops into the sluice boxes, remaining sub-1'' material passes through the nugget trap into the final.

Next, the screen deck further classifies the material, and sub-.25 (6.35mm) material drops into the sluice boxes, remaining sub-1'' material passes through the nugget trap into the final riffle set for capture, and larger rocks get discharged.

The sluicing system has three boxes that are independently adjustable, gold recovery is excellent. It often exceeds 95%, even with fine gold down to 200 mesh. The key to such remarkable recovery is because our design was based on the performance deta found in a landmark technical report on sluice boxes and reffle systems.
