Discussion on Sand Producing Technology of Artificial Gravel Production System in Large and Meduim-sized Hydropower Projects
YANG Wei-shan;Guangxi Hydroelectric Construction Bureau;
In large and medium-sized hydropower projects,the artificial aggregate system often produce sand by using of rod mill,vertical shaft crusher or by using them together. The paper analyzes the sand producing rules of rod mill and vertical shaft crusher, and discusses the problems related to sand producing technology such as opening-closing cycle,selection of dry or wet production method,as well as the control of fineness modulus, stone power content and moisture of produced sand etc.
