Magnetic materials are important basic functional materials in the electronics industry, which are widely used in home appliances, consumer electronics, automotive electronics, industrial power supplies, communications, intelligent robots, environmental protection energy, aerospace and other fields. Sintered ferrite pre-sintered material is a semi-finished material between raw materials and permanent magnet materials, which will become permanent magnet materials after secondary processing. Sintered ferrite pre-sintered material, which is processed into permanent magnet material for the second time, is mostly used in high-end electronic products such as automobiles and computers. So, is Raymond mill suitable for ferrite grinding machinery and equipment?
Raymond mill for ferrite grinding machinery and equipment is applicable, and is generally used in the sintered ferrite pellet grinding section. Sintered permanent ferrite pre-sintered materials, powders, permanent ferrite magnets and other process technologies are manufactured according to the technical requirements and technical standards of different products, equipped with different equipment, processes and raw material formulas. Under normal circumstances, raw materials and auxiliary materials (including agent A and agent B developed by the company) are dried after mixing, pre-firing, ball milling, dry pressing (or wet pressing) in accordance with the requirements of the design data, and are made into granules or powders according to the technical parameters of homogeneous powder and heterogeneous powder, stamping and magnetic field forming, forming coarse semi-finished products and then selling them after sintering, grinding, cleaning process, and testing qualified packaging.
Judging from the above sintered ferrite preparation process, the ball mill is generally used for front-end grinding, and the sintered ferrite after granulation also needs to be pulverized once, while the sintered pellet ferrite grinding machinery and equipment usually use Raymond mill. Raymond mills play an important role in the sintered ferrite pellet grinding process. After sintering, the pellets need to be ground and scattered, and the Raymond mill can be re-ground into a fine powder with a diameter of about 2um after adjusting the appropriate speed. Ferrite grinding machinery needs to be in a closed state during operation, so a closed-circuit system Raymond mill can be used.
The metal content of sintered ferrite pellets is high, generally up to more than 70%, and the wear and tear of ferrite grinding machinery and equipment will be relatively large, and it is necessary to use wear-resistant materials for Raymond mills, Guilin Hongcheng, as a professional mill manufacturer in the industry, is deeply involved in the research and development and production of wear-resistant materials Raymond mills, and its products are known for their excellent quality and efficient performance. This series of Raymond mill is specially designed for the fine grinding of hard materials such as sintered ferrite, which can ensure excellent wear resistance during processing, effectively extend the service life of the equipment, and improve the grinding efficiency and finished product quality.For equipment consultation, please send me an email [email protected].
