| 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. | |
