In recent years, the construction of high-speed railways is in a very important position. Compared with the construction of expressways, the investment in railway construction is large, the construction period is long, and the scope involved is wide. It can effectively promote the construction materials, engineering machinery and other markets. According to the calculation of 600 billion yuan for high-speed railway infrastructure investment, the share of civil engineering projects is about 55%. This means that the amount of civil engineering investment in China this year will reach 330 billion yuan. Among them, the demolition cost is about 50 billion yuan, the cost of subgrade construction is about 50 billion yuan, the construction cost of bridges and culverts is about 110 billion yuan, and the tunnel is about 110 billion yuan. Henan Hongxing Crushing Equipment Co., Ltd. is the largest crusher manufacturer in Central Plains.
These projects involve a wide range of construction machinery products, such as earth and rock machinery, lifting machinery, crushing machinery, sand making machinery, concrete machinery, piling machinery, etc.. All named engineering machinery products, without exception, are involved in railways. Possible in construction. Among these products, earth-rock machines are the most used ones. Bulldozers, excavators, loaders, crushers, sand makers, and milling machines all play their roles.
No matter whether it is the highway construction or the construction of high-speed railways, it will not be able to use a lot of gravel and concrete aggregates, and according to the new operating indicators, it will put more and more higher granularity and gradation for the new concrete and gravel aggregates. The requirements can be said to be entirely in accordance with international standards. Aiming at the new requirements of high-speed railways for concrete aggregate grain type and grading, the domestic famous mining machinery R&D manufacturer Henan Hongxing Mining Machinery Co., Ltd. designed and manufactured the high-speed railway and highway aggregate aggregate production line aggregate aggregate sand and sand grade. With reasonable, good shape, particle content can be controlled within 3-5%. Especially for basalt crushing, Henan Hongxing has found that the general basalt production process based on years of on-site construction experience has found that the stone material produced by the jaw crusher-cone crusher-counter impact crusher often has a high content of needle flakes and cannot satisfy the expressway. Or the need for high-speed railway construction, and wear-resistant parts of impact crusher are easy to wear, which is unfavorable for cost control. In response to this situation, crushing production experts of Henan Hongxing Mining Machinery Co., Ltd. found that the use of VSI5X centrifugal impact crusher (high efficiency sand making machine) can solve this problem. After using the VSI5X series centrifugal impact crusher (high efficiency sand making machine) to carry out technical transformation, the product needle-like content was reduced to 4.8%, compared with the process line with the impact crusher alone as the final crushing process, the yield increased by 30-35. %; Due to the increase of the crushing and shaping process, the crushing ratio and the processing capacity are increased, so that the output is greatly increased. Compared with the direct impact crusher used as the final crushing process to process the gravel, the wearing parts of the equipment wear reduced by 25%; due to the use of cone crusher or impact crusher as the secondary crusher, the metal consumption of the high-efficiency vertical axis impact crusher The amount is small, so the consumption of wearing parts is greatly reduced during the entire process.
