The birth of crusher promotes the development of the whole crusher machine industry, with the development of technology also appeared a lot of models and types, for our grass-roots construction bring a tremendous promoting role.
Sand maker equipment due to the building standards is different and different demands on material and fineness of discharging is mainly divided into vertical shaft impact crusher (sand making machine), jaw crusher, impact stone crusher, cone crusher and so on. Now available sand is limited, continuous mining, making the standard international sand fall sharply. With the increasingly high building standards, the standards for sand and gravel aggregate production also will increase, this promoted the technology of sand making equipment continues to develop, so new type sand making machine and manufactured sand equipment emerge in response to the needs of times.
If an infrastructure project with less material, you can purchase directly from the sand quarry. But the vast majority of railways, highways, bridges, hydropower and other major projects, located in the mountains or deep valleys, narrow construction site, construction schedule tight, large amount of concrete work, concrete construction with high strength, strict with the quality requirements of sand and gravel aggregate. Therefore scheme out with the level of modernization of manufactured sand processing equipment, ensure the project required sand and gravel aggregate, can realize the whole project production supply in regulation, is the fundamental purpose that the artificial sand and gravel processing plant designed. Sand and gravel aggregate is required for large-scale projects, major projects such as the Three Gorges Project main materials. To develop railways, highways, bridges, hydroelectric power and other base installation, the great demand is high quality sand and gravel aggregate.
