Description

TECHNICAL FIELD

[0001] The utility model relates to concrete recycling technical field especially relates to a concrete recycling and cyclic processing equipment. BACKGROUND

[0002] The concrete recycling and cyclic processing equipment is a professional equipment for processing concrete waste and recycling, which mainly comprises a feeding system for receiving and conveying concrete waste, a crushing unit for crushing large concrete waste into smaller particles, and a screening and grading module for screening and grading the crushed particles according to particle size.

[0003] For example, CN214863896U discloses a concrete processing device that can recycle and crush crushed materials.

[0004] However, in current concrete recycling and cyclic processing technologies, there is a lack of grading and screening structure, which means that the crushed concrete materials can only be collected and stored in a mixed state, and the particles of different sizes and shapes are mixed together, making it difficult to effectively separate the recycled aggregates that meet the standard particle size for different building purposes. The mixed aggregates without screening are used to produce recycled concrete, which hinders the uniform wrapping of cement paste due to the excessive large particles, and the workability is unbalanced due to the lack of small particles, resulting in large dispersion of concrete strength and poor durability, which seriously affects the safety of building structures. For road engineering, it is difficult to compact the base, the void ratio is out of control, and a stable support system cannot be formed. Under the repeated action of vehicle load, the road surface is prone to potholes, settlement, cracks, and other diseases, which not only shortens the service life of the project, but also increases maintenance costs, and hinders the healthy development of the concrete waste recycling industry.
