The sand stone is the main material in the construction of water conservancy

Sand is sand (gravel), eggs, collectively referred to as the stone stone, stone, stone and other materials, particle size greater than 5mm aggregates known as coarse aggregate is less than 5mm, stone, known as the fine aggregate as aggregate, sand. The sand stone is the main material in the construction of water conservancy. The sand come from? In recent years, the state of resources conservation advocacy, many places prohibit the exploitation of natural sand, have adopted the production of artificial aggregate. Aggregate production is the use of crusher machinery of gravel, stone, stone and other minerals, and iron ore, slag, tailings and other crushing processing system. With the wide application of artificial sand and stone, the process of many kinds of processing equipment, in order to save the cost of a lot of customers will choose the scheme of a gravel and sand came out at the same time, the processing scheme of the process.

The coarse broken - two crushing and screening and gradation adjustment - fine crushing (sand), sand washing. Thick broken machine for jaw crusher, crushing machine is two times of impact crusher and cone crusher, fine crushing machine for impact crusher is the sand making machine. Sand and gravel (egg) Ishihara material by crushing of the product, the maximum size of the general control in the broken machine allows maximum feed particle size. According to the terrain conditions and production, should be in the coarse crushing equipment after or in between the two crushing and screening equipment set up semi finished products yard, adjusting the bin can also set a smaller capacity. The crushing plant products transport to the screening and re screening classification, and the excess aggregate transport again to crushing workshop processing cycle path. In the design of artificial aggregate processing system, the general configuration of cone crusher and impact crusher, sand making machine at the same time allocation, gravel and sand at the same time, is the cone crusher and crushing stone available after vibration sieve to sieve piled up, another part can be transported to the sand gravel machine made sand, two sand can be configured according to a certain proportion, but also can be stacked separately, so as to improve the production efficiency.
