Removing fine iron contaminants with magnetic filters

By Chemical Engineering |

The Dry Vibrating Magnetic Filter (DVMF; photo) is specifically designed to remove very fine iron-bearing contaminants from hard-to-flow fine powders, such as lithium, which makes it well-suited for both lithium producers and users. The standard design of a DVMF consists of a solenoid electromagnet that generates a magnetic field into the bore of the separation zone. A filter element of expanded metal placed in the separation zone concentrates the magnetic flux of the magnetic field. This produces scores of high-gradient collection zones that capture magnetic contaminants as feed material filters through the element. — Eriez Manufacturing Co., Erie, Pa.
