Ceramic insert Raymond mill Ring、roller

雷蒙磨磨环及磨辊是雷蒙磨的主要易损件， 磨环及磨辊是直接与物料接触的配件，目前多选用合金钢-65Mn 或高锰钢-Mn13，在物料强烈冲击载荷作用下，及破碎过程中的挤压，碾磨作用，他们易出现宏观断裂失效，同时由于物料与他们之间有相对摩擦切削作用，这些耐磨件的磨损相当严重，一般情况下，雷蒙磨在使用一段时间以后就要换磨棍。

针对这一情况，DJM 选用高锰钢为基材的陶瓷复合材料，即基体采用高锰钢（或高铬铸铁），同时在基体上嵌铸具有高耐磨性的陶瓷随形加强筋，在保持高锰钢原有的加工硬化耐冲击性能的同时提高了高锰钢的耐磨强度，陶瓷复合铸造磨环及磨辊的使用寿命约为常规高锰钢的2倍以上。

Raymond grinding ring and roller are the main wearing parts of Raymond grinding, grinding ring and roller are directly in contact with the material of the accessories, the current selection of alloy steel -65Mn or high manganese steel -Mn13, under the strong impact load of the material, and crushing process extrusion, grinding action, they are prone to macro fracture failure. At the same time, due to the relative friction cutting effect between the material and them, the wear of these wear-resistant parts is quite serious, under normal circumstances, Raymond mill will be changed after a period of time. In view of this situation, DJM selects high manganese steel as the substrate ceramic composite material, that is, high manganese steel (or high chromium cast iron) is used as the matrix, and ceramic shaped reinforcement with high wear resistance is embedded in the matrix, which can maintain the original work hardening and impact resistance of high manganese steel while improving the wear resistance of high manganese steel. The service life of ceramic composite casting grinding ring and grinding roller is more than 2 times that of conventional high manganese steel. 高锰耐磨强度，陶瓷复合铸造磨环及磨辊的使用寿命约为常规高锰钢的 2 倍以上。
