Grinding head liner

　　The first shield wear-resistant professional production of grinding pad, lining board, ball mill, grinding plate, unique dual metal composite process, to ensure that the grinding pad lining resistance and toughness, but also provides grinding pad lining customization and improvement services.

　　The geometry of the grinding head lining plate is designed reasonably, and the grinding pad plate is the lining plate on the inner wall of the grinding head end cover or the simplified end cover (because the flat end cover is welded on the simplified wall). Its main function is to protect the inner wall of the end cover from abrasion by abrasive and material. If the design is reasonable, it will play a certain role in grading.

　　The geometry of the grinding pad is different, and the service life and scrap rate are different. On the first aspect board head lining service life and scrap rate, first wear shield designed according to the actual situation of the mill lining board reasonable grinding geometry, improve mill head lining life and reduce the scrap rate, so as to improve the operation of the mill rate and reduce metal consumption and production cost.
