Faster and more affordable to build high-speed railway art
Sand making production line is usually composed by vibrating feeder, jaw crusher, vertical shaft impact crusher (sand making machine), vibrating screen, sand washing machine, belt conveyor and centrally electric control and etc. The design output is generally 50 - 500 tons / hour. It is widely used in the construction of high-speed railway.
In the construction of high-speed railway, the requirement of aggregate and concrete aggregate is relatively high. The equipment of Liming sand making production line has many features as below:
1 high degree of automation
2 low operating costs
3 high crushing rate
4 saving energy
5 large output
6 less pollution
7 easy maintenance
The artificial sand is produced in line with national standards for construction sand. The artificial sand has uniform particle size, good shape and rational assignment. It plays an important role in project of high-speed railway.
With the fast development of high-speed railway and other infrastructure, the requirement for aggregate is higher, the quality requirements for aggregate is more and more strict. Natural sand can’t satisfy the actual standard of concrete aggregate. With a great deal of construction projects and shortage of construction aggregate, research and development of efficient new system of sand making production line equipment is needed for production and processing of mineral resources. As the market's continued demand for aggregate resources, it will bring the new sales for equipment of sand production line
It is very simple to obtain raw materials of artificial such as river gravel, rocks and mine tailings. The high-speed railway constructions generally use basalt, and basalt is high hardness and irregular size. The process general uses Jaw crusher - Impact Crusher for basalt mining, but Impact Crusher wear seriously. And flakiness content of products more than 10%, resulting in poor product sale. It can not satisfy requirements of the high-speed railway and highway construction. Liming Heavy Industry found that 5X series high efficiency centrifugal impact crusher (new sand making machine) can be changed through technological transformation with a lot of practice, the flakiness content of product will be down to 4.8%.This technology is compared with only using Impact crusher as the final crushing process, the output can be improved 30%.
Sand production line of Liming Heavy Industry serves many high-speed rail projects, such as China: Harbin (Harbin - Dalian) Changchun line, Wu Guang (Wuhan - Guangzhou) Yueyang line, Shi-Tai (Shijiazhuang - Taiyuan) Yangquan line,ZhengXi (Zhengzhou - Xi'an) Sanmenxia high-speed railway construction. Liming Heavy Industry sand production line is high efficiency and low energy. The final product has excellent shape. In the river gravel, sand making with construction waste and tailings, metal ore crushing, production of quartz sand, slag processing and other fields, Liming sand making production line show more technological advantages which the others don’t have, and it is effective to ensure supply of high-quality aggregate of the highway, railway, high building, hydroelectric dams, ports and concrete mixing station.
