What is crusher blow bars?

Crusher blow bars are the main impact crusher wear parts, which also called impact crusher liner, impact crusher hammer, and impact crusher break plate. Crusher blow bars are thick slabs of metal, typically some mixture of chrome, that are forged for the purpose of effectively breaking apart material like asphalt, concrete, limestone, etc. Often in sets of 2, 3, or 4, blow bars are inserted into an impact crusher’s rotor where they are able to strike material needing to be processed.

As an important component of horizontal shaft impact crushers, blow bars come into direct contact with material and provide a powerful impact force. HSI crushers and their blow bars are designed to fracture material quickly, resulting in high production rates and reduced costs-per-ton when compare to other types of crushers.
