The Automatic Rotary Magnetic Separator (Mag Spring®) is specially designed for poorly flowable or bridging-prone powders. Featuring rotating magnetic bars up to 14000 Gs, it ensures smooth material flow and efficient iron removal without clogging. The automatic rotary cleaning system eliminates manual cleaning downtime, greatly improving productivity.
Built from 304/316L stainless steel with PLC-controlled operation, it offers continuous, hygienic, and high-intensity magnetic separation for food, chemical, plastic, and powder processing industries. Ideal for improving purity, flowability, and overall process efficiency.
Food Processing: Sugar, flour, starch, spices, and powders that tend to bridge or stick.
Chemical and Pharmaceutical Industry: Powders with resin or adhesive components that reduce flowability.
Plastic and Rubber Production: For granules and recycled materials requiring high-purity and continuous operation.
Battery and Powder Metallurgy: For fine metal powders or precursors where ferrous contamination affects product consistency.
Particularly effective for sticky, fiber-filled, or humid materials where manual cleaning or static grids frequently clog.
The Mag Spring® Automatic Rotary Magnetic Separator is a next-generation magnetic filtration system specifically engineered to handle poorly flowable, cohesive, and bridging-prone powders or granules.
Featuring rotating high-intensity magnetic bars (up to 14000 Gauss), this unit ensures continuous material flow and stable separation efficiency, even when processing sticky, fibrous, or moisture-laden materials.
The built-in PLC-controlled automatic cleaning mechanism minimizes manual intervention and production downtime — a major advancement for facilities that demand consistent product purity and hygiene.
| Customer Challenge | Mag Spring Solution |
|---|---|
| 1. Poor Flowability – Powders and granules with low mobility often stick and reduce magnetic efficiency. | Rotating magnetic rods actively mix and spread the material, ensuring consistent flow and uniform exposure to the magnetic field. |
| 2. Material Bridging – Static grids easily form bridges or clogs, causing downtime and product loss. | Continuous rotation and gentle agitation break bridges automatically, maintaining smooth material flow. |
| 3. Low Manual Cleaning Efficiency – Manual cleaning is labour-intensive and requires frequent shutdowns. | The automatic self-cleaning system discharges collected ferrous debris without stopping production, reducing labour and downtime costs by up to 90%. |
Static magnetic grids often cause bridging when powders with poor fluidity accumulate and block the flow path.
The rotating magnetic bars of this system agitate the product stream, break bridging formations, and enhance flow uniformity, ensuring uninterrupted throughput.
Traditional manual cleaning requires line stoppages and operator labor.
The Mag Spring® automatic rotary design enables self-cleaning during operation — iron contaminants are automatically discharged without manual dismantling, saving time and labor cost.
Equipped with rare-earth Neodymium (NdFeB) magnets, each bar generates a surface magnetic field up to 14000 Gauss, effectively capturing fine ferrous particles as small as micron μm.All high-intensity magnets in the Automatic Rotary Magnetic Separator are rigorously tested to ensure optimal performance for sticky, low-flow, and bridging-prone powders. This ensures reliable ferrous particle separation without clogging or interruption. All designs, safety, and testing procedures comply with international magnetic performance standards, providing verified magnetic efficiency and long-term durability for food, chemical, and plastic industries.
Built entirely from 304 / 316L stainless steel, with full welding and polished internal surfaces, the separator meets FDA and EU food-grade hygiene standards.
Sealed bearings and drive systems ensure reliable operation in harsh environments.
The system supports automated timing control, cleaning cycle programming, and optional sensor feedback for intelligent production management.
Easily integrated into existing powder handling lines or conveying systems.
As the material flows through the separator, the rotating magnetic rods continuously stir and distribute the powder, preventing agglomeration and bridging.
Ferrous particles are attracted to the rod surface by the high-intensity magnetic field and held there until the automatic scraper system activates.
During the cleaning cycle, each magnetic rod is retracted and scraped automatically, depositing the collected contaminants into a sealed collection box — ensuring continuous 24/7 operation without manual intervention.
