Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing machine devices, in particular to a centrifugal ore dressing machine for ore dressing. Background Art

[0002] Centrifugal concentrator is abbreviated as centrifuge. It uses the high-speed rotation of the centrifuge to generate a large centrifugal force to strengthen the re-selection process and make the fine mineral particles more effectively recovered.

[0003] The existing technology has the following problems:

[0004] The existing centrifugal concentrators do not have a quantitative structure to limit the amount of ore particles that can be added at a time. Workers often add ore at will. If too much ore is added to the centrifugal concentrator, the separation rate of the concentrate will be low, and part of the concentrate will be discharged with the tailings. If too little ore is added, it will cause low work efficiency and waste of manpower.

[0005] To this end, we proposed a centrifugal concentrator for ore dressing to solve the above-mentioned drawbacks. Utility Model Content
