Nelson centrifugal gold selector
Short centrifuge centrifugal concentrator, also called centrifugal chute. At present, many different types of centrifuges, but the basic structure of the same. Produce large centrifugal force centrifugal concentrator in high-speed rotation, strengthen the re-election process, the fine particles are more effective recycling, it has successfully solved the full recovery of micro fine, therefore, widely used for recovery of tungsten, tin, iron and other mineral mud.
Structure of the centrifugal concentrator: centrifugal concentrator assisted by the institutions and separating mechanism is composed of two parts. 1 sorting mechanism. Centrifugal concentrator drum structure for its sorting, showed a hollow cone-shaped drum, drum inner surface of the slope 3O ~ 5O, it can be welded steel, aluminum or glass steel, drum is fixed on the shaft through the chassis, and together with the axis of rotation. The 2 auxiliary mechanism, centrifugal concentrator more aid agencies mainly to the mining equipment, the main part of discharging device, cleaning device and their action program control device.
Working principle:
The drum of the centrifuge to transfer a certain number of high-speed rotation, wall slurry ore from the control points to the mine mouth to the mine by two points into the drum. Pulp with high-speed rotating drum, under the action of centrifugal force, rotate the heavy mineral deposits in the inner wall of the drum and the drum, light mineral particles in the slurry to a certain differential rotation with the drum, during rotation to the helix angle to the mine by the end of the drum rotation in the direction of flow to the row of mine slope end to end, the discharging mine tailings discharged, namely. After 3 minutes of the ore feed device automatically turn away from the original normal position, stop to the drum to mine tailings, stay after row, row ore mine is automatically turned from the original normal location for the interception of concentrate, and then HP flush water valve automatically opens, a high-pressure water cleaning will be deposited in turn concentrate drum the inner wall of the down, concentrate rushed after high pressure water valve closes automatically, to concentrate after row, row ore mine, mine is to automatically reset is mine to begin the next election don't cycle.
