The Concentrators: Rather then haul material to the water, you can bring a lightweight, efficient power sluice to the source. The power sluice can work remote placer deposits hundreds of feet away from the water source.
The hopper design washes clay and debris with a high pressure washing spray bar and all washed material becomes classified to minus 1/2 inch for selective recovery. The spray bar is equipped with a water valve for ease of controlling the flow in the sluice. A garden hose port is included and can be used for cleaning cracks and crevices.
The sluice itself is constructed with heavy duty latches, rolled top edges and a superior hopper adjustment system. The recovery system features ribbed black rubber matting for quick visual identification of values, Hungarian riffles over miners moss for fine gold recovery and expanded metal over ribbed matting for final separation.
Equipped with an adjustable independent leg support system that enables the power sluice to be assembled on any type of terrain in a matter of minutes.
The Combinations: Keene has combined the popular power sluice and portable dredge to create an entirely efficient recovery system that can be used in most any situation. This versatile machine can be equipped with a 2 1/2 or 3 inch suction hose for dredging.
The sluice box works extremely well for dredging because the material is pre-classified before entering the sluice box. Combination units are ideally suited for shallow water areas with the power sluice being so simple to set up and requiring less water then a standard dredge to operate. The 175 model series can also be equipped with a T-80 air compressor for diving.
