Description

Technical Field

Graphite itself has good natural floatability and hydrophobicity, so conventional graphite ore can be purified by flotation process. During the purification process, in order to protect the large flakes of graphite, the process generally adopts a process flow of multi-stage grinding, multiple separation, and re-grinding and re-separation of rough concentrates. The rotation of the rotor of the flotation machine forms a negative pressure, and the efficiency of forming the negative pressure is relatively low, and there is an easy leakage phenomenon during the scraping process of the foam scraper.
