New generation of sand making machine pushed by Henan Hongxing

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) December 6, 2011 -- As the main materials of concrete aggregate system, artificial sand and gravel aggregate are widely used in the high-speed railway, highway, municipal construction, hydropower projects.So the artifical sand making machine update constantly for the customers' requirments. Henan Hongxing Mining Machinery company developed a kind of highly efficient sand maker ,which introduce the new technology, promote the sand technology and infrastructure development.

From the early 1960s, traditional dry sand processing mathod had turned up in China.But the traditional technology have several fatal disadvantage,such as the poorly equipped,small production, dust hazard,big noise, environmental pollution and so on.They matched the high energy consumption and high costs but didn't solve the problem of environmental pollution. Henan Hongxing Machinery improved the first vetical impact crusher (PCL series sand making machine)and finished the world's advanced level high-performance sand making equipment – VSI type sand making machine, which is comprised of rotor, spindle, crushing chamber, motor, transmission, automatic control systems, lubrication systems, and steel and other components. And the main wear parts,example the rotor matrix, throwing hoppers, sub-feed pan, anvil , adopts wear and impact resistance alloy materials.All of them are provided with the long life and easy replacement. The crush form is divided into 'rock on rock' and 'rock on iron'.According to material compressive strength, abradability,there are four working forms: central with cascade feeding 'rock on rock' and rock on iron'; central feeding 'rock on rock'and 'rock on iron'.


In conclusion,VSI Type sand maker is the international advanced level of the new generation of energy-saving, efficient crusher. It is suitable for brittle materials with Mohs hardness under nine, not suitable for viscous material and rock with much dirt.
