water cooling electromagnetic separator for Kaolin

Take kaolin raw materials and appropriate amount of dispersant and add water to prepare a slurry with kaolin content of 50wt %, stir fully, and obtain a thin slurry with kaolin content of 10wt %; The dispersant was sodium hexametaphosphate and the addition amount was 25mg/l. Add urea sulfur dioxide to the thin stock, and adjust the ph of the stock to 9; The stirring time was 30min and the reaction temperature was 60℃. PTMS magnetic separator can improve the whiteness of kaolin products.

PTMS magnetic separator

The amount of urea SO2 was 4% of the mass of kaolin. The ph of the slurry was adjusted to 2, and oxalic acid (3% of the mass of kaolin sample) was added. The reaction temperature was 60℃ and the stirring time was 30min. After filtration, washing and drying at 105℃, the kaolin product is obtained by PTMS magnetic separator after first whitening. After the first whitened kaolin product is crushed, water is added to prepare a slurry with a concentration of kaolin and a content of 10wt %;

what is magnetic separation method？

Under the condition of 90℃, sio2 with 10% kaolin mass and naoh with 40% kaolin mass were added, stirring and reaction continued for 40min, and h2so4 solution with 50% kaolin mass was added at a constant and slow speed, then precipitation, filtration, washing, and drying at 105℃ were carried out. PTMS magnetic separator The whitened kaolin is obtained.
