The high-intensity plate-type magnetic separator is a premium magnetic separation device utilized in the fields of mineral processing and material purification. It is specifically engineered for the efficient separation of weakly magnetic minerals—such as hematite, manganese ore, and ilmenite—or for the removal of ferrous impurities. Its core features include a high-intensity magnetic system and a unique plate-type structure, enabling the precise capture of weakly magnetic components within the material stream. The magnetic field distribution is exceptionally uniform and free of “dead zones,” making it particularly well-suited for the separation of fine-grained materials with particle sizes under 2 mm. It is most frequently deployed in the beneficiation and upgrading of non-metallic minerals, such as silica sand and kaolin. The plate-type magnetic separator can be seamlessly integrated into production lines across the mineral processing, metallurgy, ceramics, chemical, and resource recycling industries.
The high-intensity plate-type magnetic separator is currently one of the leading pieces of equipment for the separation of weakly magnetic materials. Classified as a specialized category of high-gradient magnetic separation equipment, it is ideally suited for the efficient capture of magnetic substances from fine particles within wet processing environments. It is widely utilized across various applications, including the beneficiation of metallic ores, the removal of impurities from non-metallic ores, and the recovery of resources from solid waste. Specific examples include the separation and purification of hematite, limonite, and wolframite. Furthermore, it is capable of removing iron-bearing impurities from non-metallic minerals—such as quartz sand, kaolin, and feldspar—thereby significantly enhancing product purity.
JXSC offers high-intensity plate-type magnetic separators in industrial-grade standard models; additionally, laboratory-scale versions can be custom-designed to meet client specifications for use in mineral feasibility testing or small-batch experimental trials. Customization options encompass adjustable magnetic field strengths, processing capacities, and construction materials (e.g., stainless steel or corrosion-resistant coatings). This equipment is capable of boosting the recovery rate of low-grade ores by 20% to 40%, while simultaneously achieving an impurity removal rate of over 99% for magnetic contaminants present in the processed material.
High-Intensity Magnetic System:
A combination of NdFeB permanent magnets or electromagnetic modules facilitates maintenance and magnetic field adjustment.
Multi-layer Sorting Structure:
Multiple layers of magnetic pole plates are stacked to increase the material contact area and enhance processing capacity.
Wear-Resistant Plate Design:
The surface of the magnetically conductive plate is coated with 304 stainless steel, polyurethane, or ceramic, providing wear resistance and extending service life.
Automatic Flushing System:
Equipped with a high-pressure water back-flushing device, it periodically flushes the surfaces of the magnetic plates and the gaps within the tank body, preventing fine-grained materials from clogging the separation channels.
Fully Sealed Transmission Structure:
All bearings and motors are equipped with multiple waterproof seals, enabling long-term, stable operation in mineral processing workshops characterized by high humidity and heavy dust.
1. Ultra-high sorting accuracy: The high gradient magnetic field accurately captures weakly magnetic particles, with a sorting efficiency of over 95%. For iron removal applications involving non-metallic minerals, it can reduce the iron content of materials to below 10 ppm, thereby meeting the stringent requirements for high-end material production.
2. Low operating energy consumption:
Adopting a new excitation coil design and a high-efficiency cooling system, the energy consumption per ton of ore processed is 20%-30% lower than that of traditional equipment.
3. Fully Automated Operation: Equipped with a PLC intelligent control system, it can automatically complete the entire process of ore feeding, magnetic separation, and ore unloading without manual supervision, resulting in low manual operation costs.
4. Multi-purpose: Plate magnetic separators are suitable for weakly magnetic ferrous metals such as hematite, limonite, manganese ore, ilmenite, and siderite, and can also be used for iron removal from non-metallic minerals such as quartz sand, kaolin, feldspar, and spodumene.
5. Long life design: wear-resistant and rust-proof materials, low maintenance cost, and adaptable to harsh working conditions.
6. High processing capacity per unit area: The maximum processing capacity of a single unit can reach 35t/h, and multiple units can be integrated to meet the large-scale production needs of large mines.
7. Intelligent operation: PLC controls the flushing cycle and feeding speed, and automatically unloads ore, reducing manual intervention.
8. Green and safe: The closed design combined with the circulating water system results in a magnetic content of less than 0.02% in the tailings, with no waste gas emissions, meeting international environmental protection standards.
9. High degree of customization: The equipment size, magnetic field strength, and supporting devices can be customized according to the user’s material characteristics, processing volume requirements, on-site installation space, and other parameters. To meet laboratory requirements, we also offer compact-scale versions. Furthermore, multiple units can be operated in series to further enhance the concentrate grade.
The plate-type magnetic separator generate a powerful magnetic field using either permanent magnets or electromagnetic coils. As material passes through this magnetic field zone, magnetic particles are attracted by magnetic forces and adhere to the surface of the magnetic pole plates. Non-magnetic particles, driven by gravity or fluid dynamics, naturally fall away or are discharged. The adsorbed magnetic particles are subsequently detached from the magnetic field zone by a discharge mechanism—such as a scraper or a flushing system—thereby achieving continuous separation.

It is suitable for processing weakly magnetic minerals—such as hematite, ilmenite, and tungsten ore—as well as for iron removal from non-metallic minerals, including quartz, feldspar, kaolin, and silica sand. The magnetic field intensity must be adjusted according to the specific mineral being processed.
Drum-type magnetic separators are primarily suited for coarse-grained, strongly magnetic ores (such as magnetite). In contrast, the plate-type magnetic separator employs a static, multi-stage magnetic pole plate structure; this design generates a higher magnetic field gradient, making it particularly suitable for the separation of ultrafine particles (-0.074 mm) and weakly magnetic minerals (such as limonite and ilmenite). Furthermore, the plate-type design features no rotating components, resulting in reduced wear and simpler maintenance.
If the moisture content of the material exceeds 5% (e.g., damp mineral powder), it is recommended to opt for a wet-type machine or to perform pre-drying.
Customizable ultra-high-gradient models are available, capable of achieving an iron impurity removal rate of up to 99.9%—suitable for applications such as purifying ceramic-grade kaolin.
It depends on the hardness of the minerals being processed. For instance, when sorting quartz sand, the service life of the polyurethane plates is approximately 6 to 12 months. The equipment features a quick-release structure to facilitate easy replacement.
