Drawer Magnetic Separators

May 08, 2025

Drawer magnetic separators are usually installed in the discharge port of powder or granular materials, which are suitable for removing iron from dry materials such as flour, milk powder, granules, etc..
They utilizes the magnetic field formed by the built-in high-strength magnetic rods. When powder or granular materials flow through the equipment, the they will adsorb the ferromagnetic impurities in them, achieving the purification and separation of the materials. Impurities are regularly cleaned to ensure continuous and efficient operation.
