Description

Technical Field

[0001] This utility model relates to the field of separation device technology, and in particular to a low-damage separation device for mixed material collection. Background Technology

[0002] Asphalt pavement recycling technology is a complete process that involves milling, crushing, and screening old asphalt pavement that needs to be repaired or abandoned, and then mixing it with recycling agents, new asphalt, and new aggregates in a certain proportion to form a mixture that meets certain road performance requirements before repaving it onto the road surface. The utilization of new materials and the on-site paving and compaction process are basically the same in this process. The main difference lies in the recycling and treatment process of the old materials.

[0003] An existing low-damage separation device for waste asphalt mixture aggregates (Announcement No.: CN110106770B) has at least the following drawbacks:

[0004] In the aforementioned patent, microwave heating is used to achieve uniform softening and reduce asphalt aging. Multi-stage cutting and screening process design reduces repeated damage, and screw conveyor circulation of substandard materials reduces manual intervention. However, the vibrating screen is prone to clogging, repeated circulation increases energy consumption, and the screening grade cannot be switched, making it unable to adapt to different recycling standards. Therefore, it is necessary to propose a low-damage separation device for mixed aggregates to solve the above problems. Utility Model Content
