Iron impurities such as scrap iron, iron ore fragments and metal debris mixed in raw mining materials are a hidden danger for aggregate production. These impurities not only wear crushing cavities, jaw plates and liner plates severely but also cause equipment jams and reduce finished aggregate purity, failing to meet high-standard construction requirements. SMP professional modular magnetic separation module solves iron impurity pollution problems thoroughly for modular crushing lines.
Equipped with high-strength permanent magnetic technology, the standalone magnetic separation module is installed at the feeding front of modular crushing lines. It automatically adsorbs and removes all ferrous impurities from raw materials before they enter crushing hosts, requiring no manual intervention during full-operation production.
Featuring modular integrated design, the magnetic separation unit supports free docking with all SMP jaw, cone and VSI crushing modules. It occupies minimal site space and can be quickly installed, disassembled and relocated along with the entire modular production line, adapting to flexible multi-site mining operations.

A high-grade concrete aggregate project in Greece adopted SMP modular magnetic separation module, completely eliminating equipment wear caused by iron impurities and raising finished aggregate purity by 19%, fully meeting high-rise building raw material standards.
