In the whole process design, the slag material is divided into vibrating screen through feeder; coarse aggregate is separated directly after vibrating screen, fine sand, powder particle, sticky particle and water enter into sand washing system through under screen chute; two-stage sand washing impeller and hydrocyclone are used to wash out fine sand, reduce mud content in sand and improve product quality; overflow and under screen mud enter into flocculation system, high concentration mud at the bottom of pool is pumped into filter press system, after filter press, form After filtering, low water content mud cake and clear water are formed, and the clear water is recycled in the system. The whole process is designed with multiple redundancies, and each subsystem is specially designed to ensure the stability and reliability of the system. Based on this process flow, the construction scene was extremely built through BIM modeling to ensure the smoothness of each module in the field splicing and installation, as shown in the figure.
