Currently, all provinces and cities in China continue to explore new ideas, by multi-channel and multi-thinking finance, vigorously develop infrastructure projects, and actively enhance the competitiveness of regional economic development. After reform and opening up, economic construction is booming, urban and rural areas have undergone rapid changes, railway, subway, and a large number of projects and infrastructure are under construction.
The high-speed development of the infrastructure open the huge market demand of aggregate, the quality of construction sand and gravel aggregate will be warmly welcomed in the market. Infrastructure projects demand for high-quality aggregate is growing, the requirements on the quality of concrete aggregate standard are increasingly stringent; and the natural sand gravel is far less than holds many lessons. a large number of projects are urgent to be started, and construction concrete aggregate of sand become a serious shortage, production and processing of mineral resources urgently need to develop new and efficient large-scale crushing and grinding equipment, so the new sand mechanical is one of the methods to solve resource shortage. It is expected that with the steady stream of aggregate demand, the market will also be driven by the sales of the new sand.
It is very simple to obtain mechanisms sand raw materials such as river pebbles and rocks; mine tailings also can be comprehensively utilized and turn waste into treasure; the following is a brief overview of the mechanism of sand production process: the production of mechanisms sand usually uses two kinds of process: dry process and wet process; dry type adopts thickness of the separator in order to remove the mechanism of sand in the soil, the wet production with sand washing machine; of course, dry or wet type should be according to the specific circumstances of the user as well as local climate to local conditions.
