World’s First 80-in. Magnetic Separator for Custom Minerals Processing

Oct. 15, 2021
Eriez's Rare Earth Roll Magnetic Separator provides maximum efficiency in the separation of weak magnetic particles for product purification applications.

Eriez has built and commissioned the world’s first 80-in. Dry High-Intensity Rare Earth (RE) Roll Magnetic Separator to satisfy unique minerals processing application requirements, according to Eriez Director of Minerals and Materials Processing Jose Marin. The Rare Earth Roll Magnetic Separator was successfully installed at the customer’s site, and preliminary findings indicate the industrial mineral upgraded by the equipment has “exceeded the expectations of the customer, even at higher than specified feed rates,” Marin reports.

Eriez Rare Earth Roll Magnetic Separators provide maximum efficiency in the separation of weak magnetic particles for product purification applications. Eriez applied sophisticated finite element analysis in magnetic circuit design to produce an energy-free separator capable of generating the exceptionally high field strengths needed to remove unwanted fine iron contaminants.

Eriez Rare Earth Roll Magnetic Separators have always been available in a variety of sizes; however, the company’s largest offering previously was a 60-in. roll width unit.

Marin says, “All Eriez Rare Earth Roll Magnetic Separators incorporate the highest strength and best quality magnet material. They combine the best engineering and operational features to provide excellent performance with hassle-free operation, inspection, and maintenance.” He adds, “We are excited that our newest 80-in. model is surpassing predicted performance levels.”
