As we all know, the speed of high-speed railway can up to 300 kilometers per hour or more, and the problem of the special terrain geography and climate also must be overcomed in actual operations, therefore, it presented a great challenge to the design and construction entity. The high-speed railway construction experienced a series of adjustments and put the security and safety in the first place. Security protection has more stringent technical specifications of concrete and aggregate grades and specifications.
According to high-performance technical requirements of concrete aggregate in special industries, Hongxing independently research and design sand making machine, deep cavity Jaw crusher, hydraulic cone crusher, Impact crusher and other products. According to previously involved in the construction of multiple high-speed railway project, Hongxing designed a whole set of sand making production line according to finished granularity gradation requirements to fully meet the quality and yield of the finished product in different sections and building needs.
Nowadays, with the economic development of Shanxi mining resources industry, mining machinery industry ha been a pillar industry of the national economy and occupies an important position in China's economic construction and social development. Common used mining machines are jaw crusher, impact crusher, cone crusher, etc. With the Shanxi energy structure adjustment, the country is also undergoing profound changes in production and management mode of Mining machinery manufacturing in Shanxi energy structure, the production scale, technology strength, management level have made a qualitative leap, and the technology research and development competition pushes crushing equipment toward a direction of large-scale, digital intelligent and eco-energy saving.
