The early permanent magnet electric drum was mainly designed to meet the simple material transportation and iron removal needs, with limited magnetic field strength and performance, and a narrow application range, primarily used in basic industrial fields with low requirements for magnetic separation. With the emergence and development of rare earth permanent magnet materials, the performance of permanent magnet electric drums has been greatly improved. Rare earth permanent magnet materials such as neodymium iron boron have characteristics like high magnetic energy product, small size, and light weight, which enhance the magnetic field strength and depth of permanent magnet electric drums, gradually expanding their application fields to industries such as cement, mining, steel, and chemical engineering.

In recent years, with the advancement of industrial automation and intelligent manufacturing, permanent magnet electric drums have been developing towards intelligence and efficiency. They now possess better speed regulation performance, energy-saving effects, and remote monitoring functions, allowing them to better adapt to different working conditions and production needs. By optimizing the design of permanent magnets, electromagnetic design, and motor structure, the efficiency of converting electrical energy into mechanical energy is further improved, reducing energy consumption to meet energy-saving and emission reduction requirements. Deep integration with intelligent control systems enables remote monitoring, fault diagnosis, automatic speed regulation, and other functions, enhancing the operational management efficiency and reliability of the equipment while reducing manual maintenance costs. Improved sealing technology, the use of higher quality materials, and advanced manufacturing processes enhance the wear resistance and corrosion resistance of permanent magnet electric drums, extending the equipment's lifespan and reducing equipment failures and downtime. Customized products and solutions are provided based on the special needs of different industries and users, such as permanent magnet electric drums with special specifications, special protection requirements, and special performance indicators.

With technological advancements and the continuous exploration of application scenarios, permanent magnet electric drums will find applications in more emerging fields, such as material transportation in the production of new energy vehicles and intelligent logistics warehousing systems. They can be used for the transportation of ore and iron selection operations, capable of removing surrounding rock and waste stones during the coarse selection stage after coarse or medium crushing of low-iron ore to enhance grade, and can also be used for sorting raw ore in the reduction closed-circuit roasting operations of hematite. In the cement production process, they are used to transport materials containing iron impurities, removing iron impurities through permanent magnet electric drums to improve the quality of cement products, and can also be used in the transportation of finished cement. They play a role in the raw material transportation and waste slag treatment processes in steel mills, effectively separating iron-containing materials from the feedstock, improving the purity of raw materials, and efficiently transporting various raw materials and products for steel production. They help remove iron impurities from porcelain clay, improving the quality of ceramic products and preventing iron impurities from causing defects during the firing process, ensuring the color and texture of ceramic products. In coal mine transportation systems, they can serve as driving components for belt conveyors, offering advantages such as good starting performance and energy savings compared to traditional driving methods, allowing for smooth startup under full load and saving a significant amount of electricity during long-term operation. In waste treatment plants, they are used for the separation of ferromagnetic materials during the garbage transportation process, facilitating subsequent waste treatment and recycling, thereby improving the efficiency and quality of waste processing.
