Asphalt concrete reclaimed material recovery system and recovery method

Abstract

The invention discloses an asphalt concrete reclaimed material recovery system and a recovery method. The system comprises a material storage module used for storing asphalt concrete; a first-stage screening module used for preliminarily screening asphalt concrete; a stripping and crushing module used for receiving the preliminarily screened asphalt concrete and stripping and crushing the preliminarily screened asphalt concrete; and a second-stage screening module used for receiving the stripped and crushed asphalt concrete and carrying out second-stage screening on the asphalt concrete; the storage module, the first-stage screening module, the stripping and crushing module and the second-stage screening module are integrally mounted and connected, and the particle sizes of asphalt concrete screened by the first-stage screening module and the second-stage screening module are sequentially reduced; the asphalt concrete recycled material is quickly scattered through the stripping and crushing module, and part of asphalt on the surface of the asphalt concrete recycled material is stripped, so that the aggregate crushing of the asphalt concrete recycled material is realized, and the caking rate of the asphalt concrete recycled material is reduced; and asphalt concrete with different particle sizes can be obtained so as to meet different requirements.

Description

technical field [0001] The invention relates to the field of recycling and processing of asphalt concrete, in particular to a system and method for recycling asphalt concrete recycled materials. Background technique [0002] With the rapid development of asphalt pavement construction in my country and the need for reconstruction and renovation of a large number of high-grade pavement, the recycling and reuse of old asphalt pavement milling materials has been highly valued and widely concerned. Recycled asphalt concrete is in the state of agglomeration and block, and it needs to be screened and crushed before secondary use, so as to ensure the stable gradation of raw materials. Although the existing screening and crushing equipment for recycled asphalt concrete can secondary crush massive and oversized materials, it does not break up and crush the agglomerated asphalt concrete recycled materials well. Existing screening and crushing equipment for recycled asphalt concrete ca...

AI Technical Summary

Problems solved by technology

The existing screening and crushing equipment for recycled asphalt concrete can solve certain agglomeration problems, but due to the high viscosity of the material itself, the agglomeration rate in the finished material after screening and crushing is still relatively high
