High-efficiency environment-friendly construction waste concrete treatment process
The invention discloses a high-efficiency environment-friendly construction waste concrete treatment process, and belongs to the field of construction waste treatment. The process comprises the following steps: carrying out primary crushing, pre-screening, primary crushing, intermediate screening, secondary crushing and finished product screening on construction waste concrete to obtain recycled aggregate with different particle size requirements. According to the process, the amount of dust and the proportion of fine aggregate generated in the production process can be reduced, and raised dust generated in the production environment is reduced; meanwhile, the treatment efficiency of the waste concrete and the quality of the recycled aggregate can be improved to a certain extent, and efficient and environment-friendly treatment of the construction waste concrete can be achieved; and the recycled aggregate with different particle sizes is applied to different types of green building material products in a manner of meeting requirements, and contributions can be made to 'waste-free cities' and 'sponge cities'.
本发明公开了一种高效化环保型建筑废弃混凝土处置工艺，属于建筑垃圾处理领域，包括将建筑废弃混凝土初破、预筛分、一级破碎、中间筛分、二级破碎、成品筛分，得到不同粒径要求的再生骨料的步骤。本发明可以降低生产过程中产生的粉尘量和细骨料比例，减少生产环境中所产生的扬尘；同时废弃混凝土处置效率和再生骨料品质也能得到一定提高，能够实现建筑废弃混凝土高效化、环保化处置。不同粒径的再生骨料满足要求的应用至不同类型绿色建材产品中，能够为“无废城市”和“海绵城市”做出贡献。
