subject: Common Production Line For Highway Construction [print this page] From the railway and roadway construction to the present high-speed railway and roadway construction , transportation road building have headed a new developing stage .And the Hangzhou-shanghai railway construction and other highway construction in China have fully pointed this point: the Chinas road building construction are experiencing a rapid development .And to the road building ,how to choose the crusher and sandstone production line have also become a vital point .To now ,what kind of crusher can achieve a better effect is still a troubling problem to someone .While with years crushing production experience ,Hongxing have receive a common popularity from the global market .And the sand stone production line are also produced by the discharging materials. And the products Hongxing have produced are including the sandstone materials and manual sands which we can also call them the sandstone production line ,which is equivalent to the combination of the sand stone production line and sand making production line.
Asphalt concrete pavement is used in either SMA or Superpave Pavement Technologythe shape and rank of aggregate has been brought up a very high demand. Especially to the content of needle plate type in the basalt, the former impact crusher processing chart cannot meet the requirement any longer. Therefore, our company puts up the newest crushing and screening processing chart-VI series of Vertical Shaft Impact Crusher to meet the need.
The high-quality aggregate produced by this production line is widely used in road surface of many highways. The features of the highway stone crushing process:
1. The quality of the product is very high. Content of needle plate type is no more than 5%. A diabase in Africa, once adopted Jaw Crusher and Impact Crusher. But content of needle plate type is more than 10%, resulting the bad sell of its product. After using VSI Series Vertical Shaft Impact Crushers, the content of needle plate type in the product is reduced to 4.7%.
2. The production improves 50% compared with useing Impact Crusher as the final processing of crushing.
3. Because we use Impact Crusher as the secondary crusher, and Vertical Shaft Impact Crusher consumes little metal, the consumption of wear-parts is reduced greatly in the whole process.
Related planning in China pushes forward that it is necessary for Chinas construction machinery industry to shift to manufacturing power and initially form own host product, basic technology, R & D and manufacturing system features of international advanced level. As for the industrial optimization and upgrading, the entire mining machinery industry should focus on the transition from production-based to service-oriented, strengthen the industrial base to solve the lag problem of the development of the infrastructure components, cultivate new industries and enhance the capability of independent innovation.
