Description

Technical Field

[0001] The utility model belongs to the technical field of magnet raw material crushing and relates to a magnet production raw material crushing device. Background Art

[0002] The raw materials of magnets mainly include metal substances such as iron, cobalt, and nickel. The internal structures of these metal atoms are special and they themselves have magnetic moments. They can be magnetized through electromagnetic induction and fix the magnetic field under certain conditions to form magnets. In addition, there are many types of magnets. According to the shape, they can be divided into block magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, wafer magnets, magnetic rod magnets, magnetic rack magnets, etc. If the magnet raw materials cannot be evenly crushed during the magnet manufacturing process, a series of problems will occur. These problems not only affect the quality and performance of the magnets, but also may lead to a decrease in production efficiency and an increase in costs.

[0003] During the manufacturing process of magnets, the particle size distribution of the raw materials has a crucial impact on the magnetic properties of the final product. If the raw materials are not evenly crushed, then there will be particles with too large or too small particle sizes in the manufactured magnets. These particles will affect the magnetic flux density and coercive force of the magnets, making the performance of the magnets unable to meet the expected standards.

[0004] During the crushing process, if the particle size distribution of the raw materials is uneven, then it may cause additional wear and damage to the crushing equipment, increasing the equipment maintenance cost. At the same time, the unevenly crushed raw materials may also generate dust and noise pollution during the production process, having an adverse impact on the environment.

[0005] In summary, uneven crushing of magnet raw materials during the magnet manufacturing process will cause a series of problems. These problems not only affect the quality and performance of the magnets, but also may lead to a decrease in production efficiency and an increase in costs. Therefore, there is an urgent need for a magnet production raw material crushing device to solve the above problems. Content of the Utility Model
