water cooling electromagnetic separator for Kaolin

Physical parameters before and after magnetic separation of kaolin samples: testing the firing whiteness of magnetic separation concentrate products, the firing whiteness was 92.4%, Fe2O3 content was reduced from 1.27% before magnetic separation to 0.40%, iron removal rate was 68.5%, and TiO2 content was reduced from 0.29% to 0.115%.

PTMS magnetic separation

 
The highly effective iron removal process of kaolin, which includes the following steps:
The magnetic separation raw material (or purified kaolin) is obtained, and prepared into 15% solid slurry, and then the magnetic separation raw material is 4%. After sodium hexametaphosphate slurry stirring for 20min, 325 mesh wet screen;

what is magnetic separation in chemistry？

 
The mixed mineral slurry was subjected to high gradient magnetic separation under 325 sieve, the magnetic field strength of high gradient PTMS magnetic separation is 1.4T, and the slurry flow rate is 1.6 cm/s, and the concentrate slurry was obtained through high gradient magnetic separator; according to the amount of alum is 4% of the quality of concentrate slurry, alum flocculation (30min), filtration, drying and packaging, magnetic separation concentrate; calcination of calcined kaolin (or calcined products), calcination of kaolin is used for whiteness test.
