gold sand selecting dredger

Product Description

GK Gold Dredger can be widely used in watercourse and near shore where contains gold richly. It is of high automation, high efficiency and high gold selecting precision. 2.Working Mode - old river bed, river bed with lots of rocks and large diameter gravels, rich underwater plant cover - gravel concentration *0%**0% 3.Working Process After excavating, the raw ores are sent into the first selecting hopper.After filtration, ores with the granularity of more than �*0mm are dumped through the conveyer belt and ores with the granularity of less than �*0mm are transported to the hopper room and then into the beater cylinders evenly. The ores are mixed in the beater cylinder by a hinge teeth and washed by a high-pressure water jet to wash away the clay. Then the ores are sifted by grading sieves(the sieve mesh depends on the actual placer gold granularity).Heavy ores fall down to the automatic wash-dressing machine through the sieve meshes. After automatic wash-dressing, the ores are sent into the precise gold concentration machine(jigger+centrifugal concentrator) to carry on the selecting procedure. At the end, the output products are high purity heavy mineral metal*-gold dust , tungsten , tin , red iron , brown iron , manganese , titanium , etc. Note: If the raw ores contain rich magnetite, a magnetic concentration device should be installed to deal with it.
