One of the important construction industry as the foundation material sand,undoubtedly contribution irreplaceable strength for the Chinese construction. In order to sand making machine industry as a link to the formation of the industrial chain is constantly improving, the upstream mining industry, machinery industry, the downstream direction of concrete, the construction industry, each industry has crossed the formation of different industry chain. The important position of sand industry is wrong. But with the rapid development of China economy,management norms for sand and gravel in the market is slightly behind, which we need to get out of tradition to innovation.

Early in our country on the battlefield is more natural production, mechanism of sand production accounted for the proportion of small. Compared with the cement production and processing, mechanization, automation level of sand industry is relatively low, the management level is relatively backward. Coupled with the sand making enterprises small and too much, the management level is low, resulting in sand making machine industry remain stagnant.

With the related state policy for improvement and environmental protection law,a batch of advanced technology of the domestic enterprises to develop new system sand machine. Large processing capacity, high output - 50-500t/h,compared with the traditional equipment and under the same power, the yield increased by 30% and stable. Vulnerability of consumption is low, the best crushing cavity material impact angle and the friction wear parts design, less than 30% of traditional equipment, low operation cost, directly reduces the use cost of equipment; product grain shape is excellent, product is cube, grain shape good, gradation, fineness modulus can be adjusted; especially for the artificial sand and stone plastic, practice has proved that the improved 30% than other traditional equipment for sand, shaping effect;
