Into the 21st century, with the accelerating urbanization, the demand for the most important material foundation as urbanization - sand is also increasing rapidly. At present, the the gravel aggregate worldwide annual production of about 28 × 108m3, the annual production of sand and gravel aggregate accounted for 45% of the world's total, has reached 13 × 108 14 × 108m3. Coarse and fine aggregate in these gravel aggregate raw materials account for about three-quarters of the total amount of concrete. Based on projections: worldwide each year aggregate size of about 21 × 108m3, China's construction industry is booming development of China's demand for coarse and fine aggregate for coarse and fine aggregate in great demand, accounting for about half of the world's demand. With the development and the future will be more and more. For such a large consumption of the Earth's natural native aggregates will be exhausted, rational development from resource use and sustainable development perspective, it is very important to seek native aggregate substitute. Production by Zhengzhou YIFAN Machinery Co., Ltd. the new generation sand maker equipment - vertical shaft impact crusher to solve the serious lack of natural sand and gravel aggregate supply and demand situation.
With the acceleration of urbanization, social gravel aggregate demand is increasing rapidly. As important raw materials for concrete aggregates obviously insufficient, a huge number of waste concrete is therefore reasonable recycling, so not only solve the problem of the lack of natural native aggregates and save waste concrete processing costs, and contribute to environmental protection, good social and economic benefits have played a role can not be underestimated.
Sand Maker prepare now has a large area of the country to promote the widely applied to construction, water conservancy and hydropower, transportation, chemical industry, metallurgy and other areas. Zhengzhou YIFAN production of sand washing machine, vibrating screen, cone crusher, jaw crusher and sand making machine supporting the use of the combination of a high efficiency, broken than large, excellent product specification gravel crushing plants, this configuration customer economy, peace of mind, peace of mind the ideal choice.
