0183;The Role of Blow Bar in Impact Crushers. In an Impact Crusher, the blow bar is mounted on the rotor and rotates at high speeds. When the rotor spins, the blow bar strikes the material fed into the crusher, causing it to shatter and break down into smaller pieces. The impact force generated by the blow bar is what facilitates the crushing process.[
