The working principle of the ball mill magnetic liner is that the magnetic liner is magnetically adsorbed to the inner wall of the cylinder, featuring advantages such as long service life, light weight, and thin thickness, resulting in a lightweight product.

Compared with traditional manganese steel liners, it has characteristics such as long service life, light weight, and thin thickness. It saves grinding balls, reduces power consumption, produces less noise, has a high operation rate, does not require bolt fixing, is easy to install, does not leak slurry, provides a good working environment, greatly reduces labor intensity, results in fewer personal accidents, and consumes fewer spare parts. According to production practice verification, using magnetic liners on large ball mills extends their service life by 4-6 times compared to manganese steel liners. Its comprehensive benefits are very significant, making it an effective measure for improving efficiency and reducing consumption in metallurgical mines, and it is well received on site.
