Method for co-processing construction waste by utilizing rotary kiln
The invention relates to the technical field of construction waste recycling, in particular to a method for co-processing construction waste through a rotary kiln. The method comprises the steps of primary crushing, iron removal, manual sorting, primary screening, secondary crushing and secondary screening, specifically, after construction waste is subjected to primary crushing through a jaw crusher, magnetic metal products are recycled through an iron remover, and the magnetic metal products are fed into an iron and steel plant to be recycled; according to the method, large light objects and non-magnetic metal products are sorted out from blocky construction waste with the small size by workers, then muck, the light objects and the blocky construction waste are screened out, and then secondary crushing treatment is conducted on the blocky construction waste through an impact crusher; and finally, the construction waste subjected to secondary crushing is screened through a circular vibrating screen, and concrete fine powder of 0-31.5 mm is screened out. The device has the advantages of being good in sorting effect, high in building waste utilization rate and the like.
本发明涉及建筑垃圾回收技术领域，具体为一种建筑垃圾利用回转窑协同处置的方法，包括；一级破碎、除铁、人工分拣、一级筛分、二级破碎、二级筛分，通过颚式破碎机将建筑垃圾进行一级破碎之后，通过除铁器回收磁性金属制品，并将磁性金属制品送入钢铁厂内回收利用；由工人从体积较小的块状建筑垃圾中分拣出大块轻质物以及非磁性金属制品，然后分别筛分出渣土、轻质物以及块状建筑垃圾，再然后通过反击式破碎机对块状建筑垃圾进行二级破碎处理；最后通过圆形振动筛将二级破碎后的建筑垃圾进行筛分处理，筛选出0‑31.5mm的混凝土细粉。本发明具有分选效果好，以及对建筑垃圾的利用率高等优点。
