Generally, in order to improve the crushing rate and the thinning degree, the internal crushing mechanism 23 of some models adopts a structure form of upper and lower two-stage double-rotor opposite rolling crushing, and waste concrete is firstly subjected to primary crushing by an upper-stage double rotor and then is further crushed into fine particles by a lower-stage double rotor, so that certain effect is achieved. However, in practice, it is found that although two-stage crushing is provided, coarse concrete particles which do not meet the use requirements are mixed in the finally obtained recycled aggregate, so that difficulty is inevitably brought to subsequent construction and use, and in addition, a large amount of dust generated in the working process of the crusher is directly diffused into the atmosphere, so that the method is not only unfavorable to physical and psychological health of operators, but also does not meet the environmental protection requirements. Therefore, the existing commonly used waste concrete crusher is still scientific and reasonable in structure, single in function and poor in practicability, cannot fully meet the actual use requirements and environmental protection requirements of a construction site, and is still not ideal from the aspects of practicability and economy.
