Keene Engineering Power Sluice CONCENTRATOR: Power Sluice Concentractor Gold Machine
High bankers Power Sluices The Power Sluice Concentrator:
A power sluice, sometimes called a highbanker or hibanker, is a piece of gold prospecting equipment that uses a pump to force water through a sluice box to mimic the natural flow of a stream. Sometimes a hopper box with spray bars and a classifier screen (or grizzly) is employed. The gravel is added slowly by shovel into the hopper box and washed over a classifier screen to remove pieces of rock that are too large to go through the sluice.
Rather then haul material to the water, you can bring a lightweight, efficient power sluice to the source. The power sluice can process and recover values from remote placer deposits hundreds of feet away from the water source. The hopper design washes gravel, clay and debris with a high pressure washing spray bar and all washed material then is classified to minus 1/2 inch in size for selective recovery. The spray bar is equipped with a water valve for ease of controlling the flow into the sluice box. A garden hose port on the manifold can be used for cleaning cracks and crevices in the bedrock and assist in cleaning the sluice box tray. The recovery tray “sluice box” is constructed with heavy duty latches, rolled top edges and a 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 Power Sluice 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 suction hose for dredging. The sluice box works extremely well for dredging because the material is pre-classified before entering the recovery tray. Combination units are ideally suited for shallow water areas. The Model PD100 series
