In recent years, both the construction in China's central or western are increasing year by year, and construction projects increasingly become large-scale and characterization, so many new materials technology with new building conceived application often constrained by the regional resources, and there is growing realized that, developing material combined with the need in the regional resource development projects helps to save construction costs and improve construction quality, which is one major event can benefit the country.
Mechanism sand with the self-compacting concrete design resources distribution is limited by geographical constraints. traditional natural sand resources used to prepare self-compacting concrete are scarce in China's Yunnan, Guizhou, Sichuan and other regions, and pit sand and artificial sand resources is rich, but this material is not the best choice for self-compacting concrete on technical characteristics, which leads to the birth of the complete set of equipment of artificial sand maker production line.
Henan Hongxing Mining Machinery Co., Ltd. creates variety sand making machines like sand making machine or sand making machinery and vsi sand maker combined with international advanced technology, and the man-made sand produced with them has good grain shape and high pass through rate, and has been the core equipment for domestic and international construction, mining, metallurgical industry, as well as highways, railways, bridges, water and electricity, mineral grinding field and mechanism sand industry.
