The TCXT Series Permanent Magnetic Cylinder is a device designed to remove ferrous impurities from granular or powder materials. It is widely used in feed mills, grain processing plants, flour mills, oil plants, and other material-handling systems. Its working principle is based on strong magnetic attraction combined with automatic separation.
1. Material enters the magnetic zone
When the material (such as maize, wheat, soybean meal, powder, or pellets) flows through the inlet, it passes around the magnetic cylinder in a free-fall or guided-flow condition.
2. Strong magnetic field captures ferrous impurities
Inside the cylinder, high-intensity permanent magnets (usually NdFeB) generate a strong magnetic field. As iron nails, metal scraps, and other ferromagnetic contaminants pass close to the cylinder surface, they are immediately attracted and firmly held on the outer shell of the magnetic cylinder.
3. Clean material flows out smoothly
The normal, non-magnetic material continues to flow downward or forward into the next processing stage—such as a crusher, grinder, or elevator—effectively preventing metal damage to downstream equipment.
4. Manual or automatic removal of impurities
Depending on the specific TCXT model, two cleaning methods are available:
Manual cleaning: Operators open the housing periodically to wipe or scrape off the collected metal particles.
Automatic cleaning: A movable outer sleeve or mechanical scraper separates the trapped iron from the magnetic field and collects it in a waste box automatically.
Since the device uses permanent magnets, it requires no electrical power and maintains stable magnetic strength over long-term operation.
Summary (One-Sentence Version)
The TCXT Series Permanent Magnetic Cylinder removes iron contaminants by attracting them with a strong permanent magnetic field as material flows through, ensuring equipment protection and improved product purity.
