Kefid's high quality sandstone aggregate crushing plant in high-speed railway construction field

The construction of high-speed railway puts high demands on the aggregate shape and gradation of concrete aggregates, especially the pin-like content in basalt (diabase) gravel. The previous simple cone crusher or impact crusher process can not meet the requirements, Kefid launched the VSI6X series vertical shaft impact crusher for crushing and shaping of the new crushing and screening process; VSI6X vertical shaft impact crusher is the optimization equipment to produce high-performance concrete (C40 and above) aggregate (gravel) and stone, after shaping by the machine, the material needle shape is not more than 5%, which can meet the technical requirements for producing the high-performance concrete (C40~C80) aggregate for the above special industry. The sandstone aggregate production system consisting of VSI6X vertical shaft impact crusher has a production capacity of 30-500 tons/hour. The finished product size and gradation are determined according to user needs, usually 0-40mm; the finished aggregate sand grade is reasonable, the grain shape is good, and the needle-like particle content can be controlled within 5%. It has been successfully used in Zhengxi (Zhengzhou-Xi'an), Wuguang (Wuhan-Guangzhou), Hada (Harbin-Dalian), Beijing to Shanghai high-speed railway project.
For high-speed railway construction sand and gravel,you can choose the complete equipment of Kefid stone production line, including C6X series jaw crusher, HPT cone crusher, VSI6X series sand making machine, YZS vibrating screen, belt conveyor and other related equipment. The whole set of coarse, medium and fine crushing equipment can produce about 5,000 square meters of standard sand and gravel.
