Development History of Sand Making Production Line

timeJan 08,2015

Along with social development, the construction of infrastructure like real estate, high-speed railway and highway at all levels in recent years is also developing fast. traditional method cannot satisfy the market demands, and given to the requirement of the solid degree of buildings, it is necessary to use more excellent sand and stone. For this reason, the sand making production line is developing rapidly. Looking back on the development history of artificial sand making technology in our country, there are generally three stages: exploration, improvement and constant innovation.


The data show that at the beginning of the 1960s, the construction of MaotiaoHe hydropower station of Guizhou was the first to apply artificial sand making technology. However, purely artificial sand making process was adopted, the production did not form scale. In 1965, artificial sand and stone production line whose production capacity was 160t/h was applied in Yingxiuwan project, laying foundation for the coming of large-scale sand and stone production line.

During the 1990s, the water development was very fast, and the construction of a group of super-huge type water conservancy projects such as Dachaoshang, Wanjiazhai, Ertan, Xiaolangdi and the Three Gorges provided god-given opportunities for the development of artificial sand making technology. The use of impact crusher sand making principle greatly reduces the abrasion of the equipment when crushing high-hardness materials. After several decades of development, the sand making production line technology in our country has made qualitative progress, and now we know more clearly that which equipment should be used to gain the minimum input-output ratio.
