Suction Dredge with MAGNETIC recovery system on market for gold, diamonds and gemstones mining
Ordinary riffles accumulate heavy black sand, most of content are magnetic minerals. Magnetic minerals have specific gravity about 4.9-5.2g/cm3, and push out valuable gemstones( SG of ruby and saphires -4.0g/cm3, SG of diamonds- 3.5g/cm3). In our dredges and sluices we use NbFeB Permannent Strong magnetic field ( B=1.5 Tesla), which removes all stong and week magnetic minerals. This also improves finest gold recovery due to fact 80% of concentrate is magnetic and removed from riffles.
Dredges are powered by twin 13 HP 188F Petrol engines with Electric starts , Electric 12 V compressor , stainless steel Power Jet and Aluminum frame on two inflatable pontoons to increase portability. Dredges mounted on floatation modules with large decks. The sluice box designed for fine and coarse gold and equiped with stainless steel riffles with stainless steel classifier .Commercial gasoline engines twin 13 HP 188F equipped with electric start and Battery charger enough for working with 12 V compressor, guarantee long life, reliability and economy. The suction system has stainess steel power jet and twin logs to for maximum suction power and abrasion resistance compare to mild steel power jets.
