What Is An Impact Crusher?
An impact crusher primarily relies on the force of impact to crush materials. Its principle of working is strikingly different from jaw and cone crushers that utilize compression to break down materials. In an impact crusher, when the materials enter the blow bar area, they get hit by the high-speed rotating hammer and are thrown to the impact ...
