Kaolin PTMS MAGNETIC SEPARATOR iron removal process, kaolin raw ore crushing, made into 20% slurry, through the spiral grading machine sand, through three different diameter of hydrocyclone continuous classification, pressure filtration, drying, magnetic separation raw materials. From room temperature to 120 degrees for 10 min; then to 350 degrees for 10 min; then to 750 degrees for 10 min and to 1180 degrees for 30min.
The quality of kaolin sample is poor, the content of kaolinite is 61.34%, contains a lot of illite, quartz, feldspar and other impurities; PTMS MAGNETIC SEPARATOR can remove the iron (FE2O3) in kaolin. Kaolinite is stacked layered, Fe is mainly adsorbed on the surface of kaolinite with iron-bearing mineral particles, Ti is adsorbed on the surface of kaolinite with iron-bearing mineral particles, Ti in kaolin with the removal of iron-bearing minerals;
Comparison of iron and titanium content and firing whiteness before and after magnetic separation of kaolin samples. Under the optimal PTMS MAGNETIC SEPARATOR condition, the Fe and Ti contents of the samples were decreased greatly, and the firing whiteness was significantly increased.
