Abstract
The invention belongs to the field of magnetic separation of solid materials, and provides a dry type permanent-magnetic separation method for magnetic particles in a particle mixture so as to solve the problem that the separation effect and the processing amount cannot be both considered in an existing magnetic separation technology. The method comprises the steps as follows: I, a non-magnetic cylinder is placed into a permanent-magnetic cylinder; II, the to-be-separated particle mixture is placed into the non-magnetic cylinder, two ends are closed by the aid of non-magnetic material covers,and the non-magnetic cylinder is fixedly connected with the permanent-magnetic cylinder; III, the permanent-magnetic cylinder is rotated intermittently in a single direction and is vibrated at the vibration interval; IV, the non-magnetic material covers are opened, the permanent-magnetic cylinder is overturned, particles, which are not attracted by the magnetic force of the permanent-magnetic cylinder, in the non-magnetic cylinder are poured out, and non-magnetic particles are separated. According to the dry type permanent-magnetic separation method, the separation effect and the processing amount are both considered, the processing amount can be up to the 100-kg level, and the good separation effect is realized.
Description
technical field [0001] The invention belongs to the field of magnetic separation of solid materials, in particular to a dry permanent magnetic separation method for magnetic particles in a particle mixture. Background technique [0002] The dry magnetic separation of particle mixture 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 that enables the separation of dry or low moisture particle mixtures. The 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, and there are serious impurities in the non-magnetic and magnetic phases after sepa...
