The Design Principle of the Structure of Magnetic Separator

Magnetic separator is a magnetic machine that has been gradually applied in recent years and it can be widely used in metallurgy and other industries as well as being used as the professional equipment for recycling dense medium. When designing the structure of the magnetic separator, the designers should combine the property and granularity of the ores as well as the requirement for separation and classification indexes and make a comprehensive consideration for the design factors. Then what are the design principles of the structure of magnetic separator?

1. The design aim of magnetic separator: advanced structure, simple composition, small size, light weight, low cost, reliable working condition, easy and convenient operation and maintenance, good working condition, good separation index and high handing capacity.

2. The selection of magnetic system: when separating lump ores with strong magnetism, even though its magnetism is strong, it is big and in the shape of square and polygon, it is not suitable to adopt the magnetic system of alternative magnetic pole along the moving direction of the ore particles to avoid magnetic stirring. To prevent some magnetic ore particles from falling into tailings, Hongxing Machinery suggests new magnetic system.

3. The improvement of high-magnetic product quality: when separating fine particles with strong magnetism, it is necessary to pole alternative magnetic system to improve the quality of magnetic products. When separating ores with weak magnetism, it is not necessary to use upper class magnetic system as the magnetism of the ores is weak and the magnetic force is small, magnetic stirring will make the magnetic particles fall into tailings.

4. The principles should be followed: the absolute value of the field density of the working area of the magnetic drum separator should be as high as possible; the radial component of the magnetic force should be high and the tangential component should be low; the magnetic field should be ensured to have sufficient working depth.
