衬板的作用
The function of the liner
1、保护球磨机筒内壁和端盖不被研磨体磨损
1. Protect the inner wall and end cover of the ball mill from abrasion.
2、调整研磨体运动状态，使研磨体在磨机运转过程中获得的能量得到合理利用。如在一仓装阶梯衬板或压条衬板时可使大研磨体的提升高度增大，使研磨体以较大的动能击碎物料，在细磨仓装波纹衬板或平衬板，可使研磨体的研磨作用增强。
2, adjust the movement state of the abrasive body, so that the energy gained by the grinding body in the running process of the mill can be used rationally. For example, the lifting height of the big grind grinding body can be increased when the staircase lining board or the bar lining plate is installed. The abrasive body is crushed by the larger kinetic energy, and the corrugation lining board or the flat plate can be installed in the fine grinding silo, which can enhance the grinding effect of the abrasive.
3、在一定程度上增强筒体的刚度。
3. To a certain extent, the stiffness of the cylinder is enhanced.
4、分级衬板可使仓内钢球按球径大小沿磨机轴向作正向分级，从而使各直径钢球在粉磨过程中充分发挥作用。球磨机衬板最常见的磨损现象是形成槽沟形。为了避免这种情况，对球磨机衬板的表面形状作了各种改进，使研磨体从分布的各种滑槽之一中落下来。
4. The grading lining can make the steel balls in the storage chamber be positively graded along the axial direction of the mill according to the diameter of the ball, so that each diameter ball can play its full role in the grinding process. The most common wear phenomenon of liner is the groove shape. In order to avoid this situation, various improvements have been made to the surface shape of the lining plate of the ball mill, so that the abrasive body falls from one of the various chutes.
