SLon-CPHGMS mainly consists of the magnetic pole, magnetic yoke,energizing coil, Magnetic medium, pulsating mechanism.The working procedure is as follows.While a direct electric current flows through the energizing coils,a magnetic filed is built up in the separating zone. At first,the separating zone is filled up with water so that the pulsating energy can be transmitted to the separating zone.Then slurry is fed from the feeding flow rates can be adjusted by the bottom valve.Magnetic particles are attracted from slurry onto the surface of the matrix.Non-magnetic particles pass through matrix and go out through the product box under the combined force action of slurry pulsation.gravity and hydrodynamic drag.The pulsating mechanism drives the slurry in the separating zone up and down, keeping the particles in the matrix pile in a loose state, so that magnetic particles can be easily captured by the matrix and nonmagnetic particles can be more easily dragged out through the matrix pile.The cyclic PHGMS can only be fed periodically. When a batch of feed is finished, the energizing electric current is switched off and the magnetic product (mags) is washed out with water.
