In industrial production processes, the presence of unwanted ferrous metals within materials can cause serious damage to production equipment and negatively affect the quality of the final product. Developed to prevent this problem, Automatic Cleaning Suspended Type Magnetic Plates have become one of the indispensable solutions of modern industry thanks to their high efficiency and low maintenance cost.

Working Principle and Technical Structure

The plate magnet is generally positioned above a conveyor belt, at a strategic point where the material flow can be controlled most efficiently. The most critical component of this system is a moving continuous belt that constantly surrounds the magnet plate. As material moves along the conveyor belt, ferrous metal contaminants are attracted by the powerful magnetic field and held securely on the cleaning belt. As the belt moves away from the magnetic field, the ferrous metals accumulated on it are automatically collected and removed from the system by dropping them off the feed conveyor into a separate collection chute. This automatic cleaning mechanism provides a continuous, uninterrupted separation process without the need for human intervention.

These systems are specifically designed for a maximum suspension height of approximately 300 mm on belts less than 1000 mm wide. However, when wider belts or a more effective attraction distance are required, larger and more powerful suspended permanent plate magnets may be needed to increase the depth and strength of the magnetic field. The sizing of the magnetic plate is determined by taking into account parameters such as conveyor belt speed, material flow rate, material depth, and the expected iron particle size.

Superior Separation Performance and Application Areas

Suspended type plate magnetic separators have proven to be one of the most effective methods for extracting unwanted iron from material carried on fast-moving conveyors. These systems are ideal for separation applications on large or small tonnages, wet or dry, fine or coarse materials. They are particularly vital in many sectors such as recycling facilities, mining, food processing, plastics, wood, glass, ceramics, and chemical industries. Automatic Cleaning Suspended Type Magnetic Plates safely and securely separate waste iron, protecting costly processing machinery (such as crushers and grinders) and helping to increase the purity of the final product. This prevents potential breakdowns on the production line, increasing operational continuity and efficiency.

The suspended type magnetic plate is one of the simplest and most cost-effective pieces of equipment for separating ferromagnetic particles from material carried on belt conveyors. In particular, Automatic Cleaning Suspended Type Magnetic Plates offer an excellent solution for materials with a denser magnetic metal particle content. They provide a larger magnetic coverage area needed to separate coarse iron pieces in areas with dense metal content that are difficult to clean. They require less space than electromagnets and are simpler to install.

Advantages of Automatic Cleaning Systems

Because it uses a permanent magnet, it does not require energy or a continuous power supply, which significantly reduces operating costs. Only the moving conveyor section used for cleaning requires periodic maintenance. The operational advantages are numerous: the possibility of shutdown due to a power outage is eliminated, ensuring uninterrupted operation. Since it is a permanent magnet, its power does not decrease or change over time (except in extreme cases such as severe mechanical impact or the breakdown or wear of the poles). This ensures that the system always operates at maximum efficiency.

Material and Structural Features

Magnetic plates are manufactured from Ceramic (Ferrite) or Neodymium (NdFeB) magnets depending on the requirements of the application. While ferrite magnets offer a more economical solution, neodymium magnets provide much stronger magnetic fields and deeper attraction distances, delivering superior performance in demanding applications. For the food industry in particular, they are manufactured from corrosion-resistant stainless steel and sealed NdFeB magnets, ensuring full compliance with food safety and hygiene standards. Flexible mounting options are available on request, including hanging by chain or attachment via a footed chassis.
