Sales of Eriez® Dry Vibrating Magnetic Filters Continue to Rise with Surging Worldwide Lithium Demand

Erie, PA—Eriez® reports a steady escalation in sales of Dry Vibrating Magnetic Filters (DVMFs) which the company says can be attributed mainly to ongoing increased worldwide lithium production, driven by growing demand for lithium-ion batteries. Eriez DVMFs are specifically designed to remove very fine iron-bearing contaminants from hard-to-flow fine powders such as lithium.

Eriez DVMFs are well-suited for both lithium producers and users. Producers pulverize lithium before it goes to the user as a very fine powder. DVMF units are placed prior to and after mill processing. As an additional check, users apply the DVMF when they receive lithium purchased from the producer.

Eriez notes that DVMF sales are climbing across the globe, most significantly in top lithium producing countries including Argentina, Australia, Canada, Chile, China and the U.S. Eriez Director of Minerals and Materials Processing Jose Marin says, “We project DVMF sales will continue to soar in upcoming years as producers work to meet growing demand for lithium-ion batteries used in electronic consumer devices as well as electric and hybrid vehicles.”

The standard design of a DVMF consists of a solenoid electromagnet which 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 which capture magnetic contaminants as feed material filters through the element.
