The suction force is strong and can absorb anything from small screws to large iron blocks weighing 150kg. The magnetic force is twice as strong as that of ordinary models. This device has high iron absorption efficiency, good sealing, compact size and high safety.
The disc carrier composed of multiple magnetic disks in series has sufficient adsorption area. An inclined elastic scraper separation device is installed between each disk. During the continuous rotation of the disk, the scraper separation device continuously scrapes off the magnetic body adsorbed on the disk and discharges the mixture into the floc bin through the reamer connected to the scraper.
Eddy current separator is mainly used to recycle scrap metal from industrial and domestic waste. Typical processing objects include: scrap copper (aluminum) power cables, aluminum products, automobile parts, non-ferrous metal debris, printed circuit board ash, glass slag containing non-ferrous metals, electronic waste, multi-metal (AI\CU, PB, ZN) mixtures, cast steel (aluminum) sand and aluminum slag, etc.
Key Features:
The system utilizes high-performance, strong-magnetic NdFeB magnets as a carrier, forming a circular magnetic system. Both sides of the NdFeB magnets are bonded to non-magnetic materials, and the inner and outer rings are vacuum-sealed. A portion of the magnetic system is immersed in the contaminated water, where it continuously rotates to continuously absorb magnetic aggregates that have formed in the water. The disc carrier, composed of multiple magnetic disks in series, provides ample absorption area. An inclined elastic scraper separation device is installed between each disk. As the disks rotate, the scraper separation device continuously scrapes off the magnetic material adsorbed on the disks. A reamer connected to the scraper discharges the mixed material into a floc bin.

Working Principle and Applications of High-Temperature Iron Removers: In the aluminum alloy smelting industry, particularly in the recycling and melting of aluminum, recycled aluminum products are melted in furnaces. Under high temperatures, these aluminum products liquefy into molten aluminum. However, iron-containing magnetic materials present in the scrap aluminum also melt, significantly increasing the iron content in the molten aluminum and leading to substandard products. To address these issues, our company has introduced high-temperature iron removers that can be immersed into aluminum melting furnaces to extract ferromagnetic objects. This solution effectively resolves the problem of excessive iron content in finished products caused by insufficient removal of magnetic materials during the initial stages of sorting.
Our company is a professional technology enterprise specializing in the research, development, production, and sales of magnetic equipment. We help customers solve the challenges of iron removal and recovery in various environments. Our products include iron removers, magnetic separators, and magnetic agitators. We have achieved remarkable success in numerous fields, including mining, food processing, non-mining impurity removal, non-ferrous smelting, magnetic conveying, power and building materials, coal mining, and docks. We also provide supporting services for numerous large-scale magnetic equipment and are committed to becoming your most trusted long-term partner.
Permanent magnetic stirring utilizes the magnetic field generated by permanent magnets to achieve contactless stirring of non-ferrous metal liquids. Permanent magnetic stirrers are based on the principle of asynchronous motors. They are analogous to a motor with a large air gap and a permanent magnet magnetic field. The magnetic inductor acts as the motor's stator, and the non-ferrous metal solution acts as the rotor. The interaction between the magnetic field and the non-ferrous metal liquid in the melt pool generates an induced potential and an induced current. This induced current, in turn, interacts with the magnetic field to generate an electromagnetic force, which propels the non-ferrous metal liquid in a directional motion, thus stirring it. The stirring speed and interval can be adjusted to suit the specific non-ferrous metal liquid. By alternating forward and reverse rotations, the non-ferrous metal liquid is stirred, generating eddy currents and turbulence, achieving a fully uniform stirring effect. Because the magnetic field of a permanent magnetic stirrer is derived from a permanent magnet, it is a very energy-efficient stirring method, with operating costs as low as one-tenth that of an electromagnetic stirrer.
The magnetic stirrer uses a magnetic field that penetrates the furnace bottom and insulation material, acting on the liquid metal and stirring it non-contact. This helps to achieve uniform alloy composition, reduce burnout, lower energy consumption, accelerate melting, and eliminate temperature differences.
An AC/DC electromagnetic stirring device uses the principle of electromagnetic induction to generate a magnetic field that acts on molten aluminum, causing it to move in a regular pattern. The electromagnetic stirring device primarily consists of a variable-frequency power supply and an inductor. The variable-frequency power supply converts 50/60Hz AC power into a two-phase or three-phase low-frequency power supply with a frequency of 0.8 to 3.5Hz. This power supply then passes a low-frequency current through the inductor, the main component of the electromagnetic stirring device, to create an alternating traveling-wave magnetic field. This traveling-wave magnetic field penetrates the stainless steel plate and lining at the furnace bottom and acts on the molten aluminum. The magnetic field induces an induced potential and current in the molten aluminum. This induced current interacts with the magnetic field to generate an electromagnetic force, causing the molten aluminum to move in a regular pattern, achieving the desired stirring effect. By varying the direction and intensity of the traveling-wave magnetic field, the stirring direction and intensity of the molten aluminum can be effectively adjusted.
The DC electromagnetic stirrer, located at the bottom of the furnace, utilizes a two-stage DC inductor. A motor drives the coil to achieve stirring. This non-contact stirring prevents contamination of the alloy solution. Under the influence of magnetic force, the upper solution fills the lower solution, creating vertical convection and stirring. This minimizes the temperature difference between the upper and lower parts of the alloy, reduces burnout, and ensures uniform alloying.
