1. Reasonably Choose Steel Balls And LinersReasonable selection of steel balls and liners is an important way to reduce liner wear. Therefore, it is necessary to start with the size and quantity of rigid balls, and the hardness ratio between the vertical roller mill liner and the steel ball, and fundamentally reduce the liner during the operation of the vertical roller mill.Generally speaking, the hardness ratio of the vertical roller mill liner to the steel ball should be controlled at about 1:0.8; secondly, it is necessary to control the ratio of the mineral powder to the steel ball in the vertical roller mill. Generally speaking, the mineral powder is about twice that of the steel ball.Improper proportions can easily cause the vertical roller mill to run under low load, which will cause the steel balls to directly impact the liner and cause the liner to break. In addition, it is necessary to pay attention to the material and hardness of the liner, and choose the heat treatment process of the liner reasonably.2. The Lining Board Adopts New MaterialsThe basic requirements for the selection of liner materials can be summarized as: high wear resistance under a certain impact load.
