The invention belongs to the field of magnetic separation of solid materials. In order to solve the problem that the existing magnetic separation technique is difficult to take account of a separationeffect and processing capacity, the invention provides a dry electromagnetic separation method of magnetic particles in a particle mixture. The method comprises the following steps: one, putting theparticle mixture to be separated into an electromagnetic cylinder, wherein the two ends of the electromagnetic cylinder are closed by non-magnetic material covers; two, intermittently rotating the electromagnetic cylinder in one direction, and applying a shock to the electromagnetic cylinder in the interim of rotation; and three, opening the non-magnetic material cover of one side of the electromagnetic cylinder, overturning the electromagnetic cylinder, pouring out the particles being not attracted by electromagnetic force of the electromagnetic cylinder in the electromagnetic cylinder, and thus separating out non-magnetic particles. The dry electromagnetic separation method takes account of the separation effect and the processing capacity, the processing capacity can be up to 100kg, andthe good separation effect can be obtained.
Description
Technical field [0001] The invention belongs to the field of magnetic separation of solid materials, and particularly relates to a dry electromagnetic separation method of magnetic particles in a particle mixture. Background technique [0002] Dry magnetic separation of particle mixtures mainly includes continuous magnetic separation technologies such as inclined plate separation technology, inclined drum separation technology, rubber roller type magnetic drum separation technology, comb tooth type magnetic drum separation technology, and intermittent magnetic separation technology such as flat plate separation technology. Technology, can realize the separation of dry or low water content particle mixture. Continuous magnetic separation technology has a large processing capacity and is suitable for dry coarse separation of large batches of particle mixtures, but its separation effect is not good. There are serious impurities entrainment in both the non-magnetic phase and the magn...
