Contrast Mechanism Sand and Natural Sand

With the continuous development of the economic construction of our country, more and more sand amount required each year to various engineering construction, and the quality of sandstone of the increasingly high demand, the use of conventional sand making machine is difficult to meet the production and quality, crusher for gold mining the artificial system sand machine, greatly simplify the construction with sand production process, improve the traditional artificial sand production, development and the economic construction of more stable.

From twentieth Century 60's has started, but the use of river sand, river sand and natural sand is still relatively common, the scope of application of basalt crusher-made sand to expand, expand the construction to highway, railway, electricity, metallurgy and other system, by retaining expanded to bridge, tunnel and hydraulic engineering, from development to masonry mortar ordinary concrete, reinforced concrete, prestressed concrete, pumping concrete, airtight concrete and shotcrete bolt supporting engineering. But due to the lag of test standards and regulations is not perfect and materials, China's construction industry of natural sand has a strong dependence, Raymond Mill Manufacturers In India in many important structures using the machine-made sand has restriction conditions. The mechanism of sand is the most natural sand in short supply or economic comparison of different last ditch plan.

Shanghai SBM machinery to remind you, in the construction of a large number of applications of machine-made sand be imperative: sand is the main material of concrete composition, along with the development of the construction industry and the construction engineering quality attention, the construction market with sand quantity is more and more big, the quality of the increasingly high demand, but the natural sand resources qualified less, the quality of the project, the destruction of farmland, water resources is becoming a serious...
