Keene 3.5 HP Power Sluice Concentrator

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.

G-Force Rock Crusher

This amazing rock crusher is ideal for the gold prospector interested in a light-weight and economical high-speed machine. Material is gravity fed into the hopper and drops into the center of a high-speed tube. The centrifugal force throws the rock into a hardened steel impact wall at speeds in excess of 400 miles per hour. The harder the rock, the easier it shatters into instant powder. If any uncrushable particles are fed into the unit it will automatically pass them without damage or hesitation. All material after crushing then passes automatically into a five-gallon bucket sealed chamber providing a low dust environment. Ideal for crushing all types of quartz, schist, limestone, etc. This new machine is also ideal for crushing black sand concentrates to release any encapsulated micron gold for further processing. Mounted to a vertical 5 horsepower engine, capable of producing up to 2 tons of grind in just one hour in a single pass. Multiple passes may be desired for finer grinds. Designed primarily as a pilot mill and not a production machine. The maximum rock size that this unit will handle is one inch. Weight 85 Lbs.
