In recent years due to the natural sand to reduce or even disappear, large-scale projects focused on engineering, such as three gorges project required artificial mechanism sand aggregate as main material. Vigorously develop the railway,highway, bridge, hydropower stations and other infrastructure, the biggest demand is high quality sand aggregate mechanism.

And the mechanism of sand stone production equipment due to different standards of construction, material and discharging fineness requirements are divided into different sand making machine , jaw crusher, impact crusher, cone crusher etc.. The existing sand resources Co., continuous exploitation, so as to meet the standard of GB sand collapse. With the more and more high standards of construction, the sand aggregate production standards increases, the prompt sand equipment technology unceasing development, so the new system sand machine mechanism sand blasting equipment emerge as the times require.
With the development of economy, national support infrastructure, such as railway, highway, bridge, hydropower project construction, the project construction cannot do without aggregates, generally a infrastructure projects, if less materials, can be directly from the purchase sand. The vast majority of railway, highway, bridge, hydro power station and other large projects,located in the mountain valley, narrow construction site, the construction time is tight, concrete engineering of large quantity, high strength concrete construction quality, mechanism of sand aggregate strictly. Therefore, design technology and dynamic economic indicators with the level of modernization of the mechanism of sand equipment and excellent mechanism sand production line, ensure the mechanism of sand aggregate gradation of the project needed, can realize the dynamic balance of production and supply engineering construction period all in regulation mechanism, is the fundamental purpose of sand processing plant design.

Since the mechanism of sand production line equipment Shanghai zenith Polytron Technologies Inc produced since the successful development of the market, by domestic and foreign investors welcome, especially open sand factory, ban stone factory etc. bring great profit space for sand and stone of investors. The company carefully design and manufacture of the impact type system sand machine, VSI sand making machine, centrifugal high sand making machine is a set of international advanced technology in one, is of high efficiency, high reliable high-quality sand products. Especially the impact type system sand machine is a kind of material to impact crusher, is the high energy low consumption equipment with international advanced level of advanced technology development our company imported similar products, is currently the most advanced, the most ideal crushing equipment, and integer.

Widely used in metal and nonmetal ore, cement, refractories, abrasives, glass raw materials, construction aggregate, artificial sand and various metallurgical slag crushing and coarse grinding, especially on the hard, hard and abrasive materials such as silicon carbide, corundum, sintered bauxite, magnesite,possesses more advantages than other types of crusher.
