Self-Cleaning Rotary Magnetic Separator

        After the material enters the equipment, it passes through the internal rotating magnetic rod assembly under the force of gravity. Driven by a reduction motor, the magnetic rod group rotates continuously at a low speed. On one hand, the high-intensity magnetic field adsorbs ferrous contaminants such as iron filings, iron powder, and rust; on the other hand, the rotational motion breaks up agglomerated material structures, preventing bridging and blockage, thereby enhancing material flowability and improving the efficiency of ferrous contaminant removal. The adsorbed iron impurities adhere to the surface of the magnetic rods. The PLC control system automatically initiates the cleaning cycle at preset intervals, using either pneumatic separation or an automatic scraper mechanism to discharge the collected iron. Subsequently, the magnetic rods reset automatically and resume normal ferrous contaminant removal, ensuring continuous and stable operation.

Features and Advantages

• Anti-blocking and Anti-bridging: The rotating magnetic rods continuously agitate the material, effectively preventing powder accumulation, caking, and blockage, making them particularly suitable for materials with poor flowability or those prone to moisture absorption.
• Fully Automatic Cleaning: The PLC‑controlled intelligent system automates the processes of iron adsorption, discharge, and resetting, eliminating the need for frequent manual cleaning and reducing labor costs.
• High‑Strength Magnetic Iron Removal: Utilizing high‑performance NdFeB magnetic materials, the magnetic field strength can reach 12,000–14,000 GS, enabling efficient removal of fine iron powders and weakly magnetic impurities.
• Continuous and Stable Operation: Designed for continuous production, this system achieves non‑stop automatic iron discharge, ensuring uninterrupted line operation.
