一些处理或运送磨蚀性物料(砂子、石灰石、矿石、煤等)的机器和设备,其零件受到相当大的磨损,以致很快损坏而不能继续使用。磨蚀性物料作用于零件工作面的条件是多种多样的,Аверин曾提出如下的磨损分类: (1)破碎时的冲击磨损; (2)磨碎时零件承受负荷引起的磨损; (3)在轻微力的作用下零件的擦伤。对于具体零件,耐磨材质的选择应按不同的磨损特性来确定。当零件是在高速冲击负载条件下工作(圆锥破碎机和
Some machines and equipment that handle or transport abrasive materials (sand, limestone, ore, coal, etc.) are subject to considerable wear and tear so quickly damaged that they can no longer be used. Аверин has proposed the following classification of wear: (1) impact wear on crushing; (2) wear on parts subjected to load during grinding; and Parts of the role of minor abrasions. For specific parts, wear-resistant material selection should be based on different wear characteristics to determine. When the part is working under high speed impact load conditions (cone crusher and
