Wet magnetic separator

PTMS magnetic separation

what is magnetic separation？

The high-quality quartz sand concentrate with a Fe2O3 content of 0.036% is obtained by the use of a wet magnetic separator. Magnetic separation is divided into dry selection and wet selection. The wet magnetic separation has the defects of large power consumption, easy wear of the medium, large production water consumption, high operation and maintenance cost, but high iron removal efficiency. The dry strong magnetic separation process is easy to operate, and the operation and maintenance cost is lower than that of the wet type, but the iron removal efficiency is low. In the magnetic separation process, the wet magnetic separator can remove the weak magnetic impurity minerals such as hematite, limonite and biotite including the continuum particles. In general, quartz sand containing impurities mainly composed of weak magnetic impurities can be selected by using a wet magnetic machine above 10,000 Oersted; for a strong magnetic mineral containing magnetite as the main impurity, it is weak. The selection effect of the magnetic machine or the medium magnetic machine is better. The iron removal effect of the wet magnetic separator is affected by parameters such as the amount of feed, the amount of flushing water, and the strength of the magnetic field, among which the magnetic field strength is the most affected. In addition, the more the number of magnetic separations, the finer the grain size of the quartz sand, and the better the iron removal effect.
