Self-made pairs of pole-type magnetic separator using materials of NdFeB.
While the particle size of materials fine, the surface area of unit particles larger, the electrostatic attraction of particles stronger, so the adjacent particles will bond with each other, the result is non-magnetic materials wrapped magnetic materials, it's easy to happen "blocking" phenomenon in the feeding, resulting in the decline of clean coal yield, thereby affecting the desulfurization rate and the rate of de-ash.
