With the development of infrastructure, urbanization, construction, road and bridge repair, the long-term demand for natural sand gradually increasing, natural sand gradually reduced, it has been unable to meet the needs of infrastructure, natural resources cycle relative relatively long, so the resources to replace natural sand is now being studied in the construction industry.
Currently, after investigation and study in addition to natural sand, there are many minerals can use mechanical processing technology, building sand, materials generally used are river gravel, pebbles, basalt, granite, limestone, slag, etc., which solves the problem of natural sand supply problems of artificial sand is made. Where the river gravel with compression, wear and corrosion-resistant properties of natural stone, artificial sand is the most suitable for the production of a green sand used in construction materials.
Artificial sand, also known as sand, Zhongxin Heavy Industry specializing in the production of ore crushers for decades, including production equipment, including sand production equipment sand, artificial sand production process gains. As river gravel sand making machine, it is commonly used river gravel sand making machine to produce sand, which is currently the most typical artificial sand industry, sand making equipment, it can be combined with jaw crusher and cone crusher and other machinery and equipment production at a more perfect construction sand and gravel aggregate.
Our VSI sand making machine, which can be configured jaw crusher and cone crusher, the maximum feed size 1200mm, which can aggregate a variety of gravel, coarse sand, fine sand, in sand, sand and other special sand. Its simple structure, easy operation, small footprint, easy installation and maintenance, energy saving, green building materials to provide infrastructure, protection of national infrastructure projects is a powerful high-quality sand and gravel aggregate supply!
