3 INCH DREDGES

Our 3 inch dredges offer extreme versatility and are ideal for small to mid-sized dredging projects. The reinforced sluice box features rolled top edges and heavy duty latches for long life and durability as well as a long sluice track adjustment for precise tilt positioning. A large woven wire mesh classifier screen and black rubber ribbed matting at the entry section of the sluice provides for better classification and instant recognition of values. The combination of miners moss and expanded metal placed under the first half of the riffle section allows for improved fine gold recovery.

Marlex Jet Flares increase suction power, diffusing material for more equal distribution into the sluice box. The Jet can be pivoted upward between the floats for ease of maneuvering through extremely shallow water. The pivoting Jet Flare and sluice can be detached from the floats and placed on level ground for use with a power jet or suction nozzle.

The flotation system has been designed with a light frame and the streamlined pontoons are equipped with 3 "stringers" on the bottom that assist in sliding over rocks in shallow water. The floats are also conveniently molded with storage indentures providing a place to set your mask, gloves, tools, or other items.

All of our 3 Inch Dredges are equipped with Model P180 pumps, PPJF3 Jet Flares, SB3F Sluice Boxes and have a dredging capacity of 3 cubic yards per hour.

Fully assembled dimensions are 73" x 46" x 13" However, the entire frame has been constructed to separate into two sections for ease of transportation and storage.

4 INCH ULTRA MINI DREDGES

This New 4” dredge is specifically designed to be lighter and more portable than standard models. The smaller, more compact 4” is ideal for packing into remote areas and is also great for quick one day outings.

The sluice box has been shortened by 8” for a total of 40” in length. The new sluice is a single stage box, however with the woven wire classifier, the long rubber damper, miners moss, rubber ribbed matting and the latest riffle designs, you will not be disappointed in the fine gold recovery.

6 & 8 INCH HEAVY DUTY PORTABLE DREDGES

This selection of 6 and 8 inch heavy duty dredges are "State of the Art" equipment for economy and portability. Large carpeted walkways on the decks can accommodate several divers and provides for ease of access around all working parts of the dredge. The sluice box sets below the surface of the water, reducing out of water lift and increasing suction power.

All models are equipped with a winch leveling system for precise tilt and sluice box adjustment. The double classification sluice design gives you excellent recovery. The first portion of the sluice containing the coarse gold can be cleaned separately without removing the lower riffle system that contains most of the fine gold. The second riffle section is covered with a .5 inch woven wire classification screen that classifies material and keeps large cobbles from entering the fine gold recovery section of the sluice box. The dredge itself is mounted on four modular Marlex flotation modules that provides for superior stability. Dimensions on all models are approximately 120" x 94" x 23" and each dredge comes with 20 feet of suction hose.

These 6 and 8 inch dredges are quite simply superior machines that must be experienced to truly appreciate their recovery capacity.

RECLAMATION DREDGES & DREDGING SYSTEMS

One of the most common misconceptions of the average person is in thinking that dredges are strictly used for gold mining. While this is what they were originally developed for, the usefulness of the dredge today is as varied as are makes and models. From oyster harvesting and marina cleaning, to complex diamond plants or simple golf course water hazard cleaning, dredges are expanding their horizons by the day.

Keene Engineering manufactures some of the most unique, powerful and versatile dredges on earth today. Dredges and dredging systems that are capable of handling nearly any type of application. If you can think of it, we can build it.

Take our Nessie Dredges for example, our crown jewel of dredges. Nessie is a state of the art machine and the first real portable cutterhead dredge on the market.

Our Nessie Dredges offer more then 6 implement options, aside from its standard revolutionary cutterhead, which make it the most versatile dredge in its class. Operations such as Hyacinth and Tule clearing are a snap for this machine and marina cleaning has never been easier!
