dry magnetic separator

3, selective flocculation
The production of scraper coated kaolin, after PTMS magnetic separator, adding flocculant, selective separation of fine quartz, pyrite, alingite and other impurities. Commonly used flocculants are sodium hexametaphosphate, polyacrylamide ammonium, sodium silicate and so on.

4. Chemical bleaching
Bleaching agents such as insurance powder were added to reduce the high-value iron of limonite and hematite in kaolin to soluble ferrous iron, or oxidizing pyrite and dyeing impurities were added, and PTMS magnetic separator was used to improve the whiteness of kaolin.

5, splittings
In the PTMS magnetic separator, the peeling is added and the fine medium ball is stirred to produce grinding peeling effect, so that the kaolin aggregate particles are separated into thin slice crystals, and the scraper coated kaolin with particle size less than 2μm and content more than 90% can be produced.
