Eriez’s explosion-proof suspended electromagnet

Eriez took ConExpo-Con/Agg 2017 as an opportunity to discuss a number of the company’s products and developments, including its dry-type suspended electromagnets.

According to Eriez, it is the only supplier today that offers dry-type suspended electromagnets that are backed by third-party certifications for installation in hazardous locations with combustible dust and flammable gas or vapor environments. Notable certifications include Canadian Standards Association (Series D800) and Underwriters Laboratory (Series 700U), Eriez says.

“Our dry-type suspended electromagnets do not contain any transformer oil inside, so there is no flammable liquid that could catch on fire,” says Bill Dudenhoefer, market manager for heavy industry at Eriez. “These magnets utilize a thermal epoxy to transmit heat to the outer magnet shell for cooling.”

Eriez developed Series 700U explosion-proof and Series 800 air-cooled separators with magnetic strength equal to Eriez oil-cooled units. They automatically remove large amounts of tramp iron from heavy burdens on belt conveyors or chutes while providing protection against fires or explosions, the company says.

The Series 700U explosion-proof and Series 800 air-cooled magnets offer the traditional quality, performance, reliability and value of Eriez electromagnets, with added features to increase safety, productivity and profitability, the company adds. Eriez dry-type suspended electromagnets are designed with a special static conducting self-cleaning belt to eliminate sparking from static electricity. A zero-speed switch stops the unit in the event of belt failure or jamming.
