AI Technical Summary
In existing technologies, it is difficult to change the depth of foam scraping by the scraper, which affects the beneficiation efficiency of low-grade phosphate ore. In particular, it is difficult to scrape accurately when the foam layer thickness varies due to different phosphorus pentoxide content.
A high-efficiency beneficiation device for low-grade phosphate rock was designed. By adjusting the position of the scraper through rotating and adjusting components, and combining it with a blower to generate and evenly distribute bubbles, the device can accurately scrape off the foam layer and ensure the full flotation of phosphate rock particles in the slurry.
This technology allows for adjustment of the scraper position based on the thickness of the foam layer, improving the recovery rate of phosphate ore and the quality of the concentrate, while avoiding the mixing of insufficiently flotated slurry and the problem of the foam layer not being collected.
