The invention provides a construction waste pretreatment process. The construction waste pretreatment process comprises the following steps of preliminary screening, air drying treatment, preliminarysorting, secondary screening, first-stage crushing treatment, tertiary screening and secondary crushing treatment, magnetic separation metal treatment, third-stage crushing treatment, quartus screening treatment and ball milling treatment. According to the construction waste pretreatment process, different types of waste substances in the construction waste can be effectively sorted out through the preliminary screening treatment, meanwhile, the various waste substances can be conveniently classified, recycled and reused, the residual comprehensive value of the construction waste is effectively improved, regenerated materials of different particle sizes can be screened out through multiple times of screening and multi-stage crushing treatment, the construction waste recycling rate is increased, the comprehensive reutilization rate of the construction waste is increased, all the values of the construction waste are comprehensively and perfectly utilized, the scientific sustainable production concept is achieved, meanwhile, greater economic benefits can be brought to production enterprises, and the product quality is guaranteed when the pretreated construction waste serves as a baking-free brick raw material.
本发明提出一种建筑垃圾预处理工艺，包括以下步骤：初步筛分、风干处理、初步分拣、二次筛分、一级破碎处理、三次筛分及二次破碎处理、磁选金属处理、三级破碎处理及四次筛分处理和球磨处理；本发明通过初步筛分处理可以有效的分拣出建筑垃圾中不同类型的废弃物质，同时便于各类废弃物质份分类回收再利用，有效的提高了建筑垃圾的剩余综合价值，通过多次筛分和多级破碎处理可以筛分出来不同粒级的再生物料，提高了建筑垃圾的综合再利用率，综合完善的利用了建筑垃圾的全部价值，实现了科学可持续生产理念，同时可以为生产企业带来较大的经济利益，保证了预处理后的建筑垃圾作为免烧砖原材料时产品质量。
