Eriez® Demagnetizing Coils Offer Low Maintenance, Reliable Operation

News for the Minerals Processing Industry

Erie, PA — Eriez® Electromagnetic Demagnetizing Coils are designed to provide many years of maintenance-free, dependable service for demagnetizing natural magnetite flowing through pipelines following recovery by a magnetic separator. These custom-engineered electromagnetic units are compact, lightweight and do not have any moving parts to wear.

The circular coil has a uniformly increasing and decreasing field with respect to slurry flow and is the standard type recommended for most applications.  The coil is coated with epoxy resin for protection from damaging moisture

Eriez Electromagnetic Demagnetizing Coils are offered in 17 sizes ranging from two to 18-inches in diameter. Standard coils operate from a 460 volt, 60 cycle, single phase AC power source. They can also be furnished for other voltages and line frequencies, if required.

These coils should be mounted so the pipe carrying the slurry to be demagnetized passes through the coil tube. The coils can be installed with either end serving as the inlet. Electrical connections are made to the coil through the junction box mounted on one end.

Capacitive power factor correction units are available and have been designed specifically for the Demagnetizing Coils. The controls have protective fusing and are separately enclosed in housings designed for surface monitoring.
