Impact crushers blow bar requires good impact resistance, especially for primary crushing, to alleviate stress concentration during impact. The material of the blow bar needs to ensure maximum wear resistance while also possessing high strength and rigidity to prevent deformation or fracture under high-speed impact force. In addition to conventional austenitic manganese steel materials, GESION's extensive alloy steel and composite material technologies better meet the requirements for blow bar usage in impact crushers, enhancing lifespan and productivity while reducing maintenance.
