Sand Production Technology Upgrade Caters to Environment Protection

Technology innovation is concerned with environment protection and resources squander. In order to reduce environment pollution and resources waste, economy, environment protection, high efficiency, building garbage reuse should be attached more importance. Multi-function new type sand making line can be more extensively applied in various fields. Sand aggregate in highway, railway, and other key state projects has to pass strict verification and inspection to ensure meeting the grain shape and grading requirements. Consequently, good compressive strength and corrosion resistance can be achieved.

In view of the source of highway gravel aggregate, the best appropriate raw materials are mainly pebbles, basalt, granite, etc. Greystone features in wear resistance, low waterline, poor conductive performance, high compressive resistance, low crushing value, strong corrosion resistance, high asphalt adhesivity, etc. Due to the reasons that it is internationally recognized; its basalt quarrying process is relative simple; materials drawing is comparably convenient, it is widely used in highway and railway construction.

In the face of such a situation, Henan Hongxing Mining Machinery carries out technology research and innovation on sand production line. The content of flat-elongated particles has dropped dramatically to 48%. Compared with using solely impact crusher in the final crushing process, the production rises by 30-35%. Because the plastic process is added, the reduction ratio and processing ability are immensely increased. The abrasion rate drops by 25%. The cone crusher or impact crusher is applied for secondary crushing. Consequently, metal consumption in high efficiency vertical impact crusher is very low.
