Impact crusher blow bar high chrome white iron martensitic and ceramic insert

CMC is a wear-resistant material that combines the good toughness of metallic materials (martensitic steel or high-chromium cast iron) with the extremely high hardness of industry ceramics. Ceramic particles of a specific size are specially treated to form a porous body of ceramic particles. The molten metal penetrates completely into the interstices of the ceramic structure during casting and combines well with the pottery particles.

This design can effectively improve the anti-wear performance of the working face; at the same time, the main body of the blow bar or hammer is still made of metal to ensure its safe operation, effectively solving the contradiction between wear resistance and impact resistance, and can be adapted to a variety of working condition. It opens up a new field for the selection of high-wear spare parts for the majority of users, and create better economic benefits.

a.Martensitic Steel + Ceramic
Compared with the ordinary martensitic blow bar, the martensitic ceramic blow hammer has higher hardness on its wear surface, but the impact resistance of the blow hammer will not decrease. In the working conditions, the martensitic ceramic blow bar can be a good substitute for the application and usually can obtain nearly 2 times or longer service life.

b.High Chromium White Iron +Ceramic
Although ordinary high-chromium iron blow bar already has high wear resistance, when crushing materials with very high hardness, such as granite, more wear-resistant blow bars are usually used to prolong their working life. In this case, a high-chromium cast iron with inserted ceramic blow bar is a better solution. Due to the embedding of ceramics, the hardness of the wear surface of the blow hammer is further increased, and its wear resistance is significantly improved, usually 2 times or longer service life than normal high chromium white iron.
