Abstract: As an aggregate production system for Yangfanggou Hydropower Station and Kara Hydropower Station, the sand and stone processing system at Shangpuzigou is designed to produce approximately 1230 tons of finished aggregate. Considering the construction characteristics of this project, the lithology of the material source and the requirement on the quality and output of the finished product aggregate, the aggregate production technology of "three-stage crushing and two-stage sand making" was adopted. In this paper, the production process and characteristics were introduced in detail, and the production capacity test of the main equipment was carried out. The results showed that the production capacity of aggregate at all levels met the design requirements and the production quality was up to standard, but there is space for further optimization of the control index of fine aggregate.
