Wet type Electromagnetic Separator

It is to provide a process with simple method, flexible process and low production cost of kaolin efficient magnetic separation PTMS magnetic separation process. This efficient iron removal process of kaolin is characterized by purifying the kaolin raw materials (1); (1) adding the magnetic separation materials into a mixed slurry of 10 ~ 20 wt%, and then adding the sodium hexametaphosphate of 2~6 ‰ for 20min, over 325 mesh wet sieve;

PTMS magnetic separation

(3) Conduct high gradient magnetic separation under the 325 mesh sieve of step (2), control the magnetic field strength of high gradient PTMS magnetic separation from 1.0 to 1.8T, and range the slurry flow rate from 0.8 to 1.8 cm/s, and select the slurry through the high gradient magnetic separation machine to obtain the concentrate slurry;

what is magnetic bead separation？

(4) according to the amount of alum as 1 to 6% of the mass of concentrate slurry, the concentrate slurry in step (3) into alum flocculation, filtration, drying, packaging to get the magnetic concentrate; (5) the magnetic concentrate obtained in step (4) to get calcined kaolin. PTMS magnetic separation The iron removal process has high efficiency, and the whitening effect is obvious.
