Sand & Aggregates Production Line
For centuries, construction aggregates, in other words, crushed stone, sand, sand gravel have been played important role in society development and fundamentally improved human’s security, mobility and enhanced mankind’s life quality. a large quantity of sand are produced from sediment deposits. However, nowadays we are experiencing a global shortage of natural sand. The huge consumption of natural sand generate large environmental pressures. So it is necessary to produce manufacture of sand or aggregates from quarried material.
Fundamental role of sand and aggregate in world
In 1850′s and 60′s, many railroads are built all over the world, which required large quantity of aggregate materials. The aggregate was used for roadbed building and ballast to support the ties. With the industry and economy development, the automobile is widely used in human’s daily life in the early 1900′s, which create an large demand for paved roads, then aggregate production increased tremendously for materials such as asphalt and concrete road pavements. In the 21st century, the restoration of transportation infrastructure such as roads, highway, bridges, airport runway, railway beds etc. will require substantial amounts of aggregates. Natural sand resources is limited in the world, so nowadays sand, gravel and crushed stone are used for producing manufactured sand.
Sand and aggregate process line
According to world market demand and customers requirements, we have development various series of sand and aggregate production line, which could produce a wide range of materials such as manufactured sand, aggregate and concrete etc. for diversified applications. The production line involves many different types of machines such as coarse crusher, fine crusher, jaw crusher, impact crusher, cone crusher, high pressure mill, sand making machine etc. By different types of machines, you could get different quality and particles size of sand and aggregate materials. With the assistance of sand washing machine, the impurity materials are washed away, high quality sand and aggregate are ready for various applications.
