Description

technical field [0001] The invention relates to an efficient and durable impact crusher, which belongs to the technical field of crushing machinery. Background technique [0002] The impact crusher is a commonly used mining machine. When the equipment is working, the rotor drives the blow bar to throw the stone entering the crusher on the impact frame, and the stone is broken by the impact force of the impact frame. However, the existing The rotor of the crusher adopts an integral blow bar. When working, regardless of the particle size of the stone, it is thrown to the impact frame by the blow bar for crushing, and repeated crushing work is done, thereby reducing work efficiency. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an efficient and durable impact crusher to avoid repeated crushing of small particle stones and improve the crushing efficiency.
