drum magnetic separator classification

Magnetic separator can be divided into low magnetic field intensity magnetic separator, the magnetic separator, high magnetic separator; generating a magnetic field in accordance with a method can be divided into electromagnetic and permanent magnetic separator magnetic separator; according to different structures and can be divided into disc, drum, roller, ring, drum, transfer cage and belt magnetic separator; sorting methods can be divided by dry and wet magnetic separator.

Can be divided into magnetic sweeper downstream magnetic separator and semi-countercurrent separator:
Downstream permanent magnet drum magnetic separator, the slurry moving direction or the direction of rotation of the cylindrical products moving in the same direction. Slurry from the tank to the mine directly into the cylinder below the magnetic system, the non-magnetic mineral particles and mineral particles by a weak magnetic cylinder below the bottom of the gap between the two discharge. Magnetic mineral particles sucked in the cylinder surface, together with the cylinder rotates to the magnetic lines at the edge of the magnetic field is weak, the mine water discharge be landed to concentrate tank. Downstream magnetic machine simple structure, large capacity, more than one series can also be used for selection of particle size of 6 ~ 0mm strong magnetic ore coarse roughing and operations, or for the recovery of the magnetic heavy media . Semi-countercurrent permanent magnet drum magnetic Plate magnets separator, to loose ore pulp is suspended from the bottom of the tank into the separation space, pulp movement direction and the direction of the magnetic force is basically the same, so the mineral particles can reach very high cylindrical magnetic force surface. In addition, the tailings from the tailings discharge hole on the bottom, so that the height of the overflow surface can be maintained in the slurry tank level. The above two characteristics determine semi-counterflow separator to receive a higher quality of concentrate and metal recovery. It is widely and to handle micro-fine (less than 0.2mm) thick ferromagnetic ore selection and selection operations. This separator can be more than one series, and raise the concentrate grade.
