The Use of Crushed Stones in the Development of High-Speed Rail

Shanghai shunky machinery has established for four years. We have rich experience of stone production line and stones crushing site with high yield. On the premise of ores with low hardness, we suggest customers to choose the first working pattern. For the ores with big hardness, you can choose second working pattern.

Before the establishment of Shanghai shunky machinery, our construction and investment of high-speed rail in China have been preceded well-organized. After people’s renunciation of inferior project, they pay more attention to the quality construction of high-speed railway. The high-speed railway is improved to promote the economic contacts of various regions enormously. In the central and western regions, the density of high-speed railway is not enough. So in the further, high-speed railway is still the priority among priorities in the working of capital construction. There will still be stable investment amounts as well.

High-speed railway construction does not need ballast stones. Because the non-slag pathway sleeper has been applied early but the high-speed rail construction needs more stones. Because the high-speed rail has higher requirement, the stones it required will be much more than that in bridge and tunnels. And the high-speed rail requires stones with tough aggregate. The stones must reach the strength grade, especially stones in the pier.

Granite and basalt are stones with relatively high strength, which is very good building stones and resources. The crushing of those materials is of some difficulties. Shanghai shunky pushes forward various stone crushing production line patterns for everyone to choose. Under normal condition, the two kinds are:

One kind is two-stage crushing. Crush by adopting the pattern of jaw crusher and impact crusher. The advantage of this crushing production line is low investment. The disadvantage is that the wear of each ton of vulnerable parts is relatively high and production cost is high in the crushing of hard rocks.

The second kind is three-stage crushing. With the adoption of working pattern of jaw crusher, cone crusher and impact crusher, the advantage of this kind of stone production line is low consumption of vulnerable parts and strong crushing capacity of hard rocks. It is more practical in the application of large scale stone crushing plants. The disadvantage is very high investment.

Jaw crusher

Jaw Crusher is ideally suitable for primary and secondary crushing. The largest compression resistance of the material to be crushed is 320MPa. The jaw crusher is widely used in stone mining, metallurgy industry, building material, highway, railway, and chemical industry. Working Principle.
