Heavy-Duty Grid Iron Remover | Large Capacity for Mining/Stone Crushing | Global Logistics Guaranteed.

• Working Principle: When the materials flow through the grille-type permanent magnet iron remover, the ferromagnetic substances in them will be adsorbed onto the permanent magnet rods inside the iron remover, thus realizing the separation of ferromagnetic substances from the materials and achieving the purpose of iron removal.
• Structural Composition
  • Magnetic Rods: Usually made of rare earth permanent magnet materials with high coercive force and high remanence, such as neodymium iron boron, etc. They have the characteristics of strong magnetic force and are not easy to demagnetize, and can effectively adsorb ferromagnetic impurities.
  • Stainless Steel Frame: It is used to support and fix the magnetic rods. Generally, 304 or 316L stainless steel materials are used, which have good corrosion resistance and strength and can adapt to different working environments.
  • Other Components: It may also include components such as a drawer-type sliding door, a discharge port, a reduction motor, a sealing device, etc. Depending on different types and functions, the components will vary. For example, the drawer-type iron remover has a drawer-type sliding door for easy cleaning, and the rotating grille iron remover has a reduction motor that drives the magnetic core to rotate.
• Types
  • Drawer-type Iron Remover: Also known as the box-type grille iron remover, it is composed of a permanent magnet magnetic rack and an outer stainless steel box. The magnetic rods are arranged in a single layer or multiple layers in a cross pattern and can be directly installed on powder pipelines and chutes. The adsorbed iron impurities are cleaned by manually pulling out the drawer. It is suitable for iron removal of various dry powder materials that fall freely.
  • Rotating Grille Iron Remover: It is mainly composed of three parts: the magnetic core, the stainless steel shell, and the reduction motor. The magnetic core is composed of strong magnetic rods, and the magnetic core is driven to rotate by the reduction motor, which solves the problems of bridging and material blocking that occur when the traditional grille-type iron remover filters powder materials with poor fluidity. It is often used to filter iron impurities in powder materials in the fine chemical industry.
  • Chute-type Iron Remover: Generally installed on the material chute, it uses the magnetic grille to remove iron from the materials flowing through the chute, which can effectively remove the ferromagnetic impurities in the materials and ensure the purity of the materials. It is suitable for some occasions where iron removal is required in the chute, such as the ceramic and chemical industries.
• Characteristics
  • Good Iron Removal Effect: Using rare earth permanent magnet materials as the magnetic source, the magnetic rods have the characteristics of high coercive force and high remanence, and can be combined into a composite magnetic system to form a high-gradient magnetic field with strong magnetic force and high capture ability. It can effectively remove strong magnet impurities, weakly magnetic iron pollutants, and other fine magnetic impurities.
  • Stable Performance: The permanent magnet rods inside can ensure that the magnetic force will not decrease by more than 5% within eight years, and the service life can reach more than 15 years, and they can be reused multiple times. At the same time, the structure is firm, not easy to block, and easy to clean, which can effectively reduce the number of iron unloading times and reduce the labor intensity.
  • Wide Application Range: It can be used to remove iron impurities in dry powder materials, granular materials, flake materials, etc. It is suitable for various working conditions of normal pressure, negative pressure, and positive pressure. The standard product is suitable for working temperatures ≤ 80 degrees Celsius, and high-temperature products that can adapt to working temperatures of up to 200 degrees Celsius can also be provided.
  • Energy-saving and Environmentally Friendly: There is no need for electrical excitation, no control circuit, no excitation coil, which saves electricity and energy. There is no problem of temperature rise, and the magnetic field strength is constant. There is also no problem of insulation and withstand voltage.
  • Convenient Installation: The structure is compact, small in size, and light in weight. According to the user's needs, a design that can adapt to the requirements of various end interfaces can be provided. The installation is simple and can be directly installed at positions such as pipelines, chutes, and bins on the production line.
• Application Fields
  • Food Processing Industry: It is used to remove iron impurities in raw materials such as flour, starch, rice, milk powder, sugar, etc., to ensure the quality and safety of food, prevent iron impurities from causing harm to the human body, and at the same time avoid iron impurities affecting the taste and color of food.
  • Chemical Industry: In the production process of plastics, rubber, pigments, dyes, coatings, etc., it can remove iron impurities in raw materials, improve the purity and quality of products, prevent iron impurities from having an adverse impact on chemical reactions, and ensure the stability of the production process and the performance of products.
  • Ceramic Industry: It can effectively remove iron impurities in ceramic raw materials, avoid the occurrence of defects such as black spots and bubbles during the ceramic firing process, improve the appearance quality and mechanical properties of ceramic products, and enhance the grade and added value of products.
  • Lithium Battery Material Industry: For the production of lithium battery anode and cathode materials, the grille permanent magnet iron remover can remove ferromagnetic impurities in raw materials, ensure the purity and performance of lithium battery materials, and improve the safety and service life of lithium batteries.
  • Other Industries: It is also widely used in industries such as mining, power, environmental protection, electronics, and metallurgy to remove iron impurities from various materials, protect downstream equipment, improve product quality, and reduce production costs.
