Building solid waste ultrafine aggregate grading process
The invention relates to the technical field of concrete aggregate, in particular to a building solid waste ultrafine aggregate grading process. The grading process comprises the following steps: s1;pretreatment: hammering building solid waste, and cutting steel bars in concrete blocks; s2; sorting treatment: sorting the pretreated solid building waste, and taking out ferromagnetic impurities andother impurities doped in the solid building waste; and s3: crushing treatment: s3-1, carrying out primary crushing treatment on the sorted solid building waste, and screening the crushed solid building waste, s3-2, carrying out secondary crushing on the building solid waste with the particle size of less than or equal to 100 mm, and then screening the building solid waste after the secondary crushing, and s3-3, carrying out three-stage crushing on the building solid waste with the particle size of less than or equal to 25 mm, and screening the crushed building solid waste to obtain recycledconcrete fine aggregate particles with the particle size of less than or equal to 5 mm. The grading process aims to provide a building solid waste superfine aggregate grading process for improving theproportion of the solid waste crushed fine aggregate.
本发明涉及混凝土骨料的技术领域，尤其是涉及建筑固废超细骨料分级工艺，其包括：S1；预处理：对建筑固废进行锤击处理，切割混凝土块中的钢筋；S2；分选处理：对预处理完成后的建筑固废进行分选处理，取出掺杂在其中的铁磁性杂质以及其他杂质；S3：破碎处理：S3‑1；将分选后的建筑固废进行一级破碎处理，破碎后的建筑固废进行筛分；S3‑2；粒径小于等于100mm的建筑固废建筑固废进行二级破碎，然后对二级破碎后的建筑固废进行筛分；S3‑3；粒径小于等于25mm的建筑固废进行三级粉碎，破碎后的建筑固废进行筛分，从而获得粒径小于等于5mm的再生混凝土细骨料颗粒。本发明的目的是提供一种提高固废破碎后细骨料的占比率的建筑固废超细骨料分级工艺。
