[0002] Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the pulp treated with reagents is stirred and aerated, so that some mineral particles are selectively fixed on the bubbles; those that float to the surface of the pulp are scraped off to form foam products, and the rest are retained in the pulp to achieve the purpose of separating minerals.

The existing discharge mechanism requires manual water addition and stirring before filtering, which easily leads to uneven mixing of reagents and a significant decrease in the quality of discharge. At the same time, most of the flotation machine's discharge mechanism is manually cleaned after use. The fan blades need to be cleaned manually with hand-held tools, thereby increasing the workload of the staff. Utility Model Content
