Sand is sand, stone egg (gravel) referred to as stone, gravel, stone, stone and other materials, particle size greater than 5mm aggregates known as coarse aggregate, i.e. gravel, less than 5mm aggregates known as fine aggregate, namely sand. The sand stone is the main material for water conservancy in architectural engineering. These sandstone from why and come? As in recent years the state of resource protection advocates, many places to prohibit the exploitation of natural sand, have used the production of artificial aggregate.

Artificial aggregates production is the use of crusher machinery of pebbles, rocks, stones and other minerals, and iron ore, slag, tailings were broken and the system for processing. With the wide application of artificial sand and stone material, the processing technology of many kinds of processing equipment, in order to save the cost of many customers will choose the scheme of a gravel and sand at the same time out, its processing scheme for the process: http://ore.china-stonecrusher.com/  

The ore - thick broken - the two crushing and screening and grading adjustment - fine crushing (sand) - sand cleaning. Thick broken machine for jaw crusher, crushing machine two times for the counterattack crusher and cone crusher, fine crushing machine for the impact crusher is sand making machine. Sand and stone (egg) Ishihara material through coarse crushed income products, the maximum particle size control in general crushing machine allows maximum feed particle size less than. According to the need of terrain conditions and production, preferably 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 transported to the screening re screening classification, and the excess aggregate transport again to crushing plant processing cycle path. In the design of artificial aggregate processing system, generally the main configuration of cone crusher and impact crusher, sand making machine and configuration, gravel and sand can at the same time, is the cone crusher or strike back type crushing gravel available after the vibration sieve sieve out will be piled up, the other part can be transported to the sand gravel machine made sand, two sand and stone can be configured according to a certain proportion, but also can be stacked separately, so as to improve production efficiency.
