8 Inch Diamond and Gold Dredges


Model 8246V

Model 8246V

8246V and 8246VE
Gas Powered Diamond and Gold Dredges

 This is one of the most cost effective and economical dredges in the industry. Both of these dredges are powered by two light weight engines as apposed to one larger, heavier engine which also increases maneuverability. Smaller engines means that they can be transported by hand without the need of larger equipment for transport. The 8246V and 8246VE are mounted on flotation modules that feature large carpeted decks that provide excellent traction and work space. The 8246VE sluice box has been extended to 16 feet in length. The first section is our 3-stage sluice box for fine & coarse gold and the second half is dedicated for the efficient recovery of gemstones.

Model 8246VE

Model 8246VE

Both of these dredges are powered by twin 23 horsepower, commercial Vanguard gasoline engines with electric starter, for long life, reliability and economy. These models include separate 5 gallon gas tanks that mount on the float for ease of refueling as well as extended running time. The suction system has an over-sized power jet and twin injectors for maximum suction power to reduce the occurrence of rock jams. This is probably the most portable 8 inch dredge on the market. All of the components can be broken down into small enough sections so that they can easily be carried by hand.

The 8246’s are equipped with a 263 compressor for an ample air supply that can accommodate two divers. These models are designed for ease of assembly and operation in the most severe of conditions.

The 8142D Series
Industrial Diesel Gold & Gem Dredge

Our 8142DE dredging for fold and diamonds in Lybiria.

Our 8142DE dredging for fold and diamonds in Liberia.

This our lightest and most portable diesel powered dredge specifically designed for the recovery of both gold and gems. Powered by a lightweight 4-cylinder turbo charged 42 horsepower Kubota diesel engine that provides extreme high performance, reliability and economy. The Kubota diesel engine drives our reliable P1500 pump that produces 1500 gallons per minute providing ample suction for depths up to 45 feet. This engine and pump combination provides extremely low fuel consumption. It is one of the world’s lightest, quietest and most compact industrial diesel powered dredge, period. The sluice box contains our world famous 3-stage sluice recovery design. The first eight-foot portion of the recovery box is designed to capture all the fine & coarse gold. The last 8 feet is primarily for diamond and gem recovery. This dredge can be disassembled into small lightweight components for ease of transportation. This dredge is so light that it can easily be hauled in the back of a truck. The engine and pump combined weigh only 500 pounds which is several hundred pounds lighter than other diesel engine and pump combinations. The dredge deck is 24 feet in length and provides a spacious platform in front of the engine measuring 8 feet wide by 6 feet long. This dredge is also equipped with a secondary dredge system that can vacuum the concentrates from the sluice box while the primary dredge is in operation. The concentrates can then be transported to shore and processed through other separation methods. The ability to clean the sluice box and operate continuously greatly enhances both recovery and productivity which provides non stop operation.

Model 8195D
Extreme Power and Extreme Depth
Super 8 Inch Industrial Gold and Gem Dredge

8195Dside

This dredge is similar to our 8160 8 Inch dredge but far more powerful and is capable of working at greater depths. This ultimately provides greater dredging capacity. The dredge is equipped with a larger engine for higher performance and equipped with an additional pump to increase capacity. We have increased the horsepower to a 95 hp Deutz diesel engine. This beast is equipped with dual 263 air compressors that are capable of providing air supply for multiple divers at greater depths. With dual P1500 pumps, this system is geared specifically to increase vacuum power and again, depth capabilities. Overall, this dredge has nearly double the suction power of any dredge in the world
The 8195D dredge is mounted to modular decks system measuring 8 feet wide and 24 feet long providing larger deck space and is also equipped with additional outrigger flotation measuring 45 x 42 inches to support the additional weight. The frame is constructed of a zinc plated steel frame with indoor-outdoor carpet fastened to aluminum decks. The flotation is provided by fourteen high impact plastic polymer pontoons for ample support to accommodate fast and rough water conditions. We use a four injector power jet vacuum system providing an increased vacuum for dredging material from deep depths. The dredge is equipped with 40 feet of suction hose and can handle up to 100 foot of suction hose and dredge to depths exceeding 80 feet.
8040SWith a new oversized “Quad Jet” jetting system you will experience fewer rock jams. The jet is designed with heavy double walled reinforcement to extend the life in extreme abrasive conditions. The sluice box is provided with a 20 foot long combination sluice, for both gold and diamonds. The diamond portion of the sluice is simple but has a very effective diamond riffle design that has been perfected over 30 years of building for the diamond field dredges in Africa. The gold sluice incorporates our world famous 3 stage sluice design. This three-stage classification system is capable of classifying smaller material for controlled flow for fine gold and gemstone recovery. The fine gold recovery on these dredges are the best in the
world. Ideal for the recovery of heavier specific gravity materials including diamonds, sapphires, rubies, garnet and any gemstone that has a heavier specific gravity than quartz. Includes the same special suction clean out system as the Model 8160, this system can vacuum the values from the sluice during operation and can eliminate the possibility of theft. Allows for removal of material to a secure area for further processing and provides a non stop dredging operation. The dredge is designed for easy set-up and operation and does not require professional assistance. The flotation is capable of accommodating hundreds of pounds of additional weight. We pride ourselves in the simplicity of the dredge and its ability to continue to operate on a trouble free basis. We have chosen the Deutz diesel engines due to long reliable life and availability of spare parts in third world countries such as Africa.
