The angle of the magnetic declination of the magnetic separator is too large or too small, and the small size affects the quality of the concentrate, so that the particles with smaller magnetic properties have the opportunity to be selected, but the grade of the tailings is lowered, which is good for the recovery rate; Too large is good for improving the quality of concentrates, because only the particles with large magnetic properties have the opportunity to be selected. If the magnetic properties are small, there is no chance to come up and enter the tailings, which will increase the tailings grade and reduce the recovery rate.
Therefore, the size of the magnetic declination must be adjusted according to the operation requirements. Generally, the magnetic declination of the production site is adjusted to be around 15°-20°. Adjust the magnetic system yaw angle. If there are no changes in operating conditions and requirements during production, do not move easily.
