In recent years, with the rapid construction development home and abroad, huge demand for construction sand sharply rise, but the amount of natural sand collected has been unable to satisfy the amount of sand required for the construction development. Sand prices began to rise year after year, due to the lack of natural sand. In order to deal with the problem that the shortage of the construction sand between production and consumption, then manufactured sand was produced.
Manufactured sand rock, also known as manufactured sand, is a form of artificial sand that is made worldwide and used to produce various industrial products including asphalt and concrete. The Primary Info website explains that manufactured sand is necessary because of an extreme worldwide shortage of natural sand. Manufactured sand is produced by crushing rock with a large impactor.
As the basic materials of concrete, cement mortar of architectural sand, Successful application of artificial sand is an indisputable fact that a large number of engineering practices (including the Three Gorges Project) has demonstrated the possibility and necessity of using sand. The sand production line consists by vibrating feeder, jaw crusher, sand making machine, vibrating screen and belt conveyor and other mining equipment. According to different process requirements, various types of mining equipment can be combined to meet the technological requirements of different customers.
Firstly, the stone was broken by primary crushing machine such as jaw crusher, impact crusher, then, the coarse sand grain was transported by belt conveyor to secondly crusher such as cone crusher for further crush. Then the broken small stone can be screened out the two major sands via vibrating screen, one kind can be transported to sand making machine, the other will be crushed again.Vibrating screen:http://www.crusher-machine.com/8.html
Stone can be found worldwide and it is often a waste material that is too large for regular construction use. Stone can be manufactured and reduced to the necessary size in order to produce a more general form of sand. The Crusher's Mill website explains that many types of stone waste material are crushed and manufactured together to form a generic manufactured sand. Any stone that is extremely large will be broken down as much as possible and then returned through the machine if necessary in order to obtain the correct texture of sand.
The small stone will be made into manufactured sand by sand making machine, after washing by sand washers(optional), the final artificial sand was made. Core equipment for manufactured sand production line is sand making machine such as VSI crusher, vsi5x crusher etc. There are three generations of sand making machine produced by our company and each generation has a superior performance and better economic benefits than its previous one. Now most of the manufactured sand are medium, coarse sand, the fineness modulus is of 2.6-3.6 in turbid, particle size distribution even and adjustable, with a certain amount of powder, rough surface, sharp edges.
