The water jacket centrifugal concentrator, also known as the Nelsen centrifugal, It is an important gravity seperator equipment that utilizes the principle of gravitational acceleration for centrifugal beneficiation. It is particularly suitable for the recovery of free gold from sand gold, vein/stone gold, and polymetallic ores, replacing traditional mercury plate operations, and is also used for the selection of gold containing heavy sand washed by chutes and gold mining boats.
The main components of this centrifugal concentrator include a centrifuge tube, a drive system, and a water jacket. Centrifugal cylinders are usually made of stainless steel or titanium alloy, with a certain thickness and corrosion resistance. The drive system includes a motor, reducer, coupling, and rotor, providing power to the centrifuge and controlling its rotational speed. The water jacket is the cooling device of the centrifuge, used to regulate the temperature of the centrifuge.
The working principle of a water jacket gold centrifugal concentrator is that the selected gold containing minerals enter the bottom of the double-layer centrifuge barrel in the form of slurry from the upper feeding pipe. Under the action of high-speed centrifugal force, the slurry slides upwards along the inner cone. Heavy monomeric gold and other heavy substances precipitate between the separators, while light substances slide upwards to the upper mouth of the double-layer centrifugal drum and are discharged through the tailings tank. At the same time, the backwash water is flushed into the inner sleeve of the double-layer centrifugal bucket through the hollow shaft to flush the heavy substances between the partitions, causing the heavier substances to deposit to the bottom, while the lighter substances are replaced by the newly entered heavy substances.
The characteristic of a water jacket centrifuge is its high separation accuracy, ability to quickly separate substances of different densities, high work efficiency, and low power consumption. In addition, its simple operation and easy maintenance make it widely applicable in the field of mineral processing.
Overall, the re selection water jacket centrifuge is an efficient and accurate mineral processing equipment, which is of great significance for improving the recovery and utilization rate of mineral resources.
