The industrial landscape is undergoing a critical transition towards heightened resource purification and equipment safeguarding. Suspended Permanent Magnets (often referred to as overhead plate magnets) serve as a primary line of defense in heavy bulk processing lines globally. By projecting deep, focused magnetic fields over rapid conveyor operations, these devices capture hazardous tramp iron, protecting downstream grinding mills, vertical impact crushers, and shredders from catastrophic mechanical failure.
Unlike electromagnets that rely on constant energy consumption, suspended permanent magnet systems operate with zero power consumption. They run 24/7 without thermal degradation, offering predictable field intensity even under severe environmental factors like high heat, heavy dust, or ambient moisture.
Installed over conveyor feeds handling high-volume ores. They remove broke drill bits, roof bolts, and loader teeth to prevent crushing chamber blockages.
Crucial for recovered scrap metal isolation. Suspended units reliably sweep cross-belt flows of domestic municipal solid waste to pull ferrous metals instantly.
Guarantees product purity in agricultural, chemical, and building material manufacturing streams by eliminating tiny micro-debris and ferrous scale.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has evolved from an ambitious engineering pioneer into a national high-tech manufacturing leader in advanced rare earth magnets. Our corporate strategy is built on four core pillars: Quality, Credibility, Technology, and Innovation.
From our state-of-the-art facility spanning 100,000 square meters in Suining, Sichuan, our 300+ engineers, researchers, and operators drive a massive annual production capacity of over 5,000 tons of permanent rare earth magnets.
Our global operations are based in Hangzhou, China, providing regional system integrations, custom client solutions, and robust technical support to clients in North America, Europe, Southeast Asia, and beyond.
Where Materials Science Meets Engineering Excellence to Define the Next Generation of Magnetic Systems.
By diffusing Dysprosium (Dy) or Terbium (Tb) selectively into the grain boundaries of sintered NdFeB, we achieve unmatched thermal stability up to 200°C while minimizing costly heavy rare earth consumption.
Utilizing advanced Finite Element Analysis (FEA), we model double-pole configurations to project a magnetic field up to 500mm below the plate. This targets deep material flows with maximum extraction force.
Our magnets are coated in triple-layer Ni-Cu-Ni, industrial epoxy resins, or high-performance Teflon. This protects them from mechanical wear and chemical exposure in humid mining environments.
The roadmap links our suspended magnets with automated discharge belts. By integrating IoT sensors, we track tramp iron load in real time to trigger discharge cycles automatically, minimizing downtime.
Laysun Magnetics solutions power a wide array of high-tech industries. Explore our primary application channels below:
High-precision sintered NdFeB magnets that drive miniature servo motors, joint controllers, and automated guiding systems.
Ultra-lightweight high-coercivity magnets that improve motor torque-to-weight ratios in aerial vehicles.

Smart and energy-efficient motor magnets for smart home setups, compressors, and ventilation blowers.
Operating a 100,000 m² factory requires unwavering compliance with international safety and quality standards. Our manufacturing lines run under strict regulatory criteria:
Approved Standards: API 6D, API 607, CE, ISO9001, ISO14001, ISO45001, and TS16949. Each suspended separator undergoes strict magnetic flux testing, spatial distribution analysis, and structural integrity evaluations prior to dispatch.
To serve the complex needs of international mineral operations, recycling plants, and heavy manufacturing lines, Laysun Magnetics coordinates supply chains through a worldwide network. Our production centers in Sichuan, coupled with logistics hubs in Zhejiang, ensure reliable deliveries and shorter lead times.
We work closely with local engineering partners to provide site surveys, system dimensioning, and commissioning support, matching magnetic separators to each site's conveyor speeds, belt widths, burden depths, and environmental conditions.
Deep technical answers to standard industry questions regarding overhead magnet installation, optimization, and safety.
