Introduction:
A permanent overband magnet is a type of magnetic separator used in industries to separate ferrous materials from non-ferrous materials. It is designed to be suspended over a conveyor belt or a vibrating feeder to attract and remove unwanted tramp iron or ferrous contaminants from the materials being transported. There are three common types of permanent overband magnets: the common permanent overband magnet, the armored belt permanent overband magnet, and the compact and lightweight overband magnet.
Permanent overband magnets, including the common type, the armored belt type, and the compact and lightweight type, play a crucial role in the industry by ensuring the removal of ferrous contaminants, enhancing product quality, protecting downstream equipment, and improving operational efficiency.
Working Principle:
The working principle of a permanent overband magnet is based on the magnetic force generated by a series of powerful permanent magnets. When the magnet is suspended over a conveyor belt, the ferrous materials passing beneath it become magnetically attracted to the magnet and are lifted and separated from the non-ferrous materials. The separated ferrous materials are then collected in a separate bin or chute for further processing or disposal.
Operation:
To operate a permanent overband magnet, it is typically installed above the conveyor belt or vibrating feeder using suspension chains or brackets.
The magnetic field created by the magnet attracts and holds onto any ferrous material present on the conveyor belt.The magnet continuously removes the captured ferrous particles, which can then be released into a separate collection area or a disposal system.
Application Industries and Necessity in Industry Application:
Permanent overband magnets find applications in a wide range of industries, including mining, recycling, quarrying, bulk handling, and waste processing. Their primary purpose is to ensure the purity and quality of the conveyed materials by removing potentially harmful or unwanted ferrous contaminants. These magnets are necessary in industry applications because they:
Prevent damage to downstream equipment: By removing ferrous materials, permanent overband magnets prevent damage to crushers, screens, shredders, and other processing equipment that could be affected by the presence of metal.
Enhance product purity: Many industries require high-quality and contaminant-free products. Permanent overband magnets ensure that the final product is free from ferrous impurities, improving its market value and customer satisfaction.
Increase operational efficiency: Removing ferrous materials before further processing reduces downtime caused by equipment failures and breakdowns. This results in increased productivity and reduced maintenance costs.
Armored Belt Permanent Overband Magne:
Due to the high ambient temperature and pieces of iron is large and irregular in above occasions, the general belt type magnetic separator can not meet the requirement.
Armored belt overband magnets are more durable and long-lasting than common overband magnets. They provide better resistance to abrasion and damage caused by sharp or heavy materials, protecting the magnetic system and increasing its service life. The steel armored belt also provides maximum magnetic attraction and easy cleaning, making it more efficient and effective than common overband magnets.
Besides,Armored belt provides excellent resistance to abrasion and damage from sharp or heavy materials. It also helps to minimize the impact of non-magnetic materials on the magnetic separation process. The stainless steel armored belt protects the magnetic system from damage and extends the service life.
Compact and Lightweight Overband Magnet:
Compact and lightweight overband magnets are designed for mobile applications where space and weight limitations are a concern. They can be easily transported to different job sites and do not require a permanent installation, making them ideal for industries such as mobile crusher,construction and demolition.
Compact and lightweight overband magnets are more mobile and versatile than common overband magnets. They are designed for use in confined spaces and areas with weight limitations. They can be easily transported and installed, reducing downtime and increasing productivity. They also provide better access to the conveyor belt for maintenance and cleaning, making them more efficient and effective than common overband magnets.
