Description

Technical Field

[0001] The utility model relates to the technical field of concrete aggregate crushers, in particular to a concrete aggregate crusher. Background Art

[0002] After searching, the Chinese patent publication number is CN213914075U, which discloses a green and environmentally friendly concrete aggregate crusher, including a main body, a first processing cylinder is provided at the inner upper end of the main body, a support frame is provided on the inner side of the first processing cylinder, and two support frames are symmetrically distributed on the inner wall of the first processing cylinder. When the utility model is in use, it drives the processing tool to rotate at high speed by a driving motor and performs the first processing on the aggregate, and then performs the second crushing processing by two crushing rollers to ensure the quality of the aggregate processing. However, when this structure is in use, all the concrete aggregates after the first processing need to be processed for the second time, so that some qualified concrete aggregates are crushed again, which undoubtedly increases the processing burden of the equipment and causes the originally qualified aggregates to be over-crushed, which not only affects the quality of the aggregate, but may also have an adverse effect on the subsequent concrete preparation process. It has poor practicality and cannot meet the use requirements. Therefore, a concrete aggregate crusher is proposed to solve the above-mentioned problems. Utility Model Content
