首先，衬板在破碎机的内部，是一条一条的突起，由于该设备属于消耗性设备，也就是在工作的时候，内部的零件随着工作时间的延长，在逐渐的磨损，当磨损达到一定程度的时候，设备就无法再顺利的进行工作，而衬板在设备内部可以起到保护作用，减少破碎机内部某些零件的磨损或者说损坏的现象，这就可以减少对于设备效率的影响，减少零件维修所需要的成本投入；
First of all, the lining board is a projection one by one in the crusher. Because the equipment belongs to expendable equipment, that is, when working, the internal parts wear gradually with the extension of working time. When the wear reaches a certain degree, the equipment can no longer work smoothly, while the lining board is in place. The spare interior can play a protective role and reduce the wear or damage of some parts in the crusher, which can reduce the impact on equipment efficiency and reduce the cost investment needed for parts maintenance.
