Abstract：Simulations based on discrete elements were conducted on the key parameters of the process of coarse crushing,medium-fine crushing,screening and transportation stage of manufactured sand.Key parameters of green preparation of manufactured sand were optimized,and the influence rules on the quality of manufactured sand were clarified.The findings were then applied in a large-scale manufactured aggregate production enterprise.The results show that during the coarse crushing and medium-fine crushing stages of manufactured sand preparation,adjusting the discharge opening size of the crushing equipment can improve rock crushing efficiency,reduce crushing energy consumption,optimize the particle size distribution of the crushed rock,and reduce wear on the equipment caused by the rock.The tilt angle of the vibrating screen in the screening stage should be between 10° and 15°,and the layout angle of the conveyer belt should be 16° during the transportation stage.
