The application of sand making machine in Concrete sand and gravel for building

Sand and gravel aggregate is actually know as sand and rock for building, which is mainly used in engineering-based, concrete, mortar and the corresponding products. These sand and gravel aggregate occupied about 75% ratio of the concrete, it is the main material of the concrete skeleton. Therefore, the quality of sand and gravel aggregate have a great impact on concrete quality, such as the aggregate strength, surface characteristics, cleanliness, size distribution, particle shape, the largest particle size, clay content and mud content and so on. With the application of concrete technology and the rapid development, Sand and gravel aggregate changes and changes in production processes.

In recent years , with the development of economic, construction sand and gravel aggregate demand is growing , especially in high-speed rail and highway construction, and ensure the rapid development of housing and other infrastructure , the quality of sand and gravel aggregate concrete made higher requirements. With the depleted natural gravel, artificial sandstone aggregate and machine-made sand, as the first high-quality sand and gravel aggregate attract much attention to the relevant industry.

For example, The crusher, sand making machine, sand making production line equipment produced by Shanghai Zenith Mining Machinery Co., Ltd. machine-made sand or manufactured sand produced by those machine, its graduation , modulus of fineness Can do better than the natural sand, Can do better than the natural sand, artificial sand and gravel sand production mechanism, and its gradation, fineness modulus may be better than natural sand, grain type completely comparable with natural sand, you can also use iron ore, limestone mines, mine tailings and other resources to produce sand and gravel aggregate, aggregate annual production capacity of 2,500 tons, that is handled in the process of mining waste rock and tailings, and the product has the advantage of stable quality, good environmental results

Nowadays, our country made ​​some progress in protecting the natural resources, production of artificial aggregate, the use of abandoned industrial waste resources, the use of specialized sand making equipment, crusher, stone production line, leading artificial sand, mechanism sand instead of natural sand and as sand and gravel aggregate concrete building material, for environmental protection, has great strategic significance for land development and construction, full use of waste resources.
