The PBM series separators are designed for strongly-magnetic ore concentration, iron removal from various materials and regeneration of heavy suspensions in industrial conditions, as well as nonferrous materials concentration. The concentration is performed in water mode.
Operating principle of separators
The pulp flows to the box and then by gravity to the bath where the pulp level to be determined by the tailboard is installed.
The pulp magnetic particles in the working area of the bath are attracted to the drum surface under the effect of the magnetic field, and when the drum is rotating, they are transported to the discharge side with the weakened magnetic field, and washed to the chute out of the flushing system under the effect of the water.
The flushing water provides for magnetic product washing from nonmagnetic particles between the drum and the bath discharge tray. Polarity interlacing in the drum direction leads to that the magnetic product floccules retained on the drum turn upside down for several times when flowing to the washing area that also promotes for their purification from nonmagnetic particles.
Nonmagnetic particles, through the discharge aperture on the bath bottom, fall into the tail cavity where the coarse, heavy fraction sediments onto the bottom of the cavity and discharges through the nozzle openings. The fine, light fraction of the nonmagnetic product (drainage) together with the water overflows the tailboard and flows out of the bath via the drain pocket.
The required quality of the separated products is achieved by changing the amount of the pulp fed to the separator, changing the magnetic system position, replacing the nozzles with different opening diameters and changing the amount of the flushing water.
The separators are widely used at the ferrous and nonferrous metallurgical enterprises.
