Blow Bars are thick slab of metal inserts into the rotor and when the rotor spins high speed the blow bar repeated striking the material to the impact plates, during this process the blow bar fractures the materials until it meets the appropriate size fall through the impact crusher chamber.
it is also call as Impact Hammer or Impactor Hammer, mixture with Chrome, Manganese ,Molly, Nikker and other alloys with different formula and heat treatments for materials like Granite, Limestone, Sandstone, Asphalt and concrete as etc.
Blow bar is a critical part during the crushing process, It is mainly made of high chrome alloy ,which are refined through special treatment and suitable for various applications like aggregates, coal, construction waste recycling. It has the best Micro-grain structure and sufficient toughness after quenching and tempering heat treatment,and the Hardness can reach HRC 60
Casteel offers high manganese ,high chrome ,High chrome with ceramic inserts ,Martensite ,martensite with ceramic inserts blow bars for varies needs ,with high hardness, long wear resistance and strong toughness without breaking.
