With the advancement of technology, new material liners have also begun to be used in vertical roller mill. For example, a composite liner composed of rubber and cemented carbide steel can ideally solve the contradiction between the toughness and rigidity of the liner and reduce the liner. The impact force received during operation. 

Compared with ordinary liners, the heat resistance and strength of composite liners have been greatly improved. Especially in terms of service life, composite liners are twice as effective as traditional liners, which greatly improves the economic benefits of enterprises. In addition, the composite liner has low working noise, light weight, and is easy to promote, but it lacks practice. However, there is a lot of room for development in dealing with the problems of liner aging and liner wear.
