安装普通衬板的磨机回转时,当钢球提升到一定高度被抛出,降落在衬板表面时产生点接触,很易将物料挤出(见图1),造成钢球与衬板之间无料而直接冲击,部分驱动功率消耗在钢球与衬板之间的冲击和摩擦上,这不仅增加了钢球的消耗和磨机的能耗,同时也降低了磨机的粉磨效率,这一点从新更换的普通衬板使用初期钢球消耗量明显增加,处理量明显降低可得到证实。 When installing the ordinary liner mill rotation, when the ball is raised to a certain height is thrown, landing in the liner surface when the point of contact, it is easy to extrude the material (see Figure 1), resulting in the ball and liner Between the material and the direct impact, part of the drive power consumption in the ball and liner between the impact and friction, which not only increases the ball consumption and mill energy consumption, but also reduces the grinding efficiency of the mill , This point replacement of ordinary liner steel ball consumption significantly increased the initial use of significantly reduced throughput can be confirmed.
