Process, equipment and system for producing plant-mixed (warm) recycled asphalt mixture
The invention discloses a process, equipment and a system for producing a plant-mixed (warm) hot recycled asphalt mixture. The process specifically comprises the following steps: feeding fine recycled coarse aggregate and new aggregate into a hot recycled material drying drum simultaneously through a cold aggregate bin of a primary mixing station, heating, screening, weighing and feeding into a main stirring pot; heating the fine regenerated coarse aggregate through a thermal regeneration system, temporarily storing, weighing and feeding into a main stirring pot; heating the oil-rich fine aggregate to a certain temperature through a cold addition system, feeding the heated oil-rich fine aggregate into a reclaimed material stirring cylinder, adding an asphalt regenerant, mixing, stirring, temporarily storing, weighing and feeding into a main stirring pot; by controlling the mixing amount to be 15-35% and combining multiple mixing modes, it is ensured that the discharging temperature and performance of the asphalt mixture meet the technical requirements, preheating and regeneration strategies of the oil-rich fine aggregate are used, the application efficiency of the regenerated material is improved, and the application range of the asphalt mixture is widened. The use amount of gravel materials can be saved, asphalt resources are saved, and carbon emission and harmful gas emission in the mixing, paving and rolling processes are reduced.
本发明中公开了一种厂拌（温）热再生沥青混合料生产工艺、装备及系统，具体包括以下掺法：将精细再生粗集料通过原生拌合站冷料仓与新集料同时进入热再生料干燥滚筒加热、筛分、称量进主搅拌锅；将精细再生粗集料通过热再生系统加热、暂存、称量进主搅拌锅；将富油细集料通过冷添加系统加热至一定温度至再生料搅拌缸，加入沥青再生剂混合搅拌、暂存、称量进主搅拌锅。通过控制掺量在15%～35%，以及多种掺加方式的组合，确保了沥青混合料的出料温度和性能符合技术要求，使用富油细集料的预热和再生策略，提升了再生料的应用效率，可节约砂石材料用量、节约沥青资源、减少在拌和、摊铺、碾压过程中的碳排放量及有害气体排放量。
