magnetic drum separator

PTMS magnetic separator The selected clay is stored in the slurry barrel for 6 ~ 8h. The pH is adjusted to 3 ~ 4, which is close to the zero electric point of the clay, so the clay particles are easy to agglomerate. The addition of alum to the pulp is helpful for the agglomeration of clay particles and promotes dehydration. The cylinder filter is a common dewatering device, which can increase the pulp concentration to 55%~60%. One of the important functions of filtration is to remove chemicals from the clay.

PTMS magnetic separator

Water spray is often used to enhance PTMS magnetic separator operation. Spray drying has become a very effective process in the clay industry, but its cost is expensive. In recent years, a new filtration process using electrophoretic properties of charged particles in an electric field has been developed. When pH>3, kaolin particles are negatively charged and surrounded by ion mist with opposite charge, forming double layers.

what is magnetic separation process？

In the PTMS magnetic separator field, the clay particles move towards the anode, while the coordination ions move towards the cathode in the ion mist. When the particles arrive at the anode, they are used to protect the anode film formed on the filter cake, anode filter cake is further dehydrated by electroosmosis method, excess water is pumped through the negatively charged filter cake capillary in accordance with the principle of electroosmosis.
