In the artificial sand and stone material production system, the sand making technology is one of the most important technologies, and the sand making equipment is the most equipment because the performance of the sand maker and the reasonability of the sand making technology influence the investment of the whole artificial sand and stone material processing system and the quality of the concrete. Next Henan Kefan Machinery will give a detailed introduction to the development course of the artificial sand making technology.

During the 1960s, the artificial sand and stone material production system at the Yingxiu Harbor hydropower station of Sichuan Province firstly conducted the research experiment using rod mill to manufacture sand and fruitful achievements were made. Since then, the rod mill sand making technology had gained long time of development in the hydropower engineering projects and artificial sand and stone material system and been widely applied in both domestic and foreign markets.

Due to the improvement of science and technology and the accumulation of production experience, vertical shaft impact crusher plant begins to attract people’s attention. With the advantages of high crushing ratio, good particle shape, high processing capacity and high content of stone powders, this sand making machine is widely applied in many large and medium-size hydropower stations and becomes the indispensable technical equipment of the artificial sand and stone material production system in the 21st century. Especially the fast development of roller compacted concrete which requires high content of stone powders makes vertical shaft impact crusher more important.

Developed till today, there are mainly two types of sand making technologies. One is rod mill sand making technology that is suitable for all kinds of concrete sand and stone aggregate processing, and the other is single vertical shaft impact crusher sand making machine technology that is suitable for processing medium-sized crushable parent rock. Of course with the continuous development of electronic technique and computer technology, the sand making production line technology will get perfect in order to make more contributions to economic construction.
