Machine Made Sand - Main Products of Engineering Stone Prodution

By the stimulating of the state policy to expand domestic demand, investment all over the roads, railways and other infrastructure increases day by day, which makes the effective implementation of major projects, lead an urgent need for a large number of high-quality sand and gravel aggregate supply. However, in order to protect the ecological balance, the State expressly prohibit the unauthorized excavation of natural sand, gravel supply fell far short of demand, which requires a lot of machine made sand. Need to build the highway along the gravel aggregate base, to ensure an adequate supply of construction aggregate production depends mainly on the production of sand making machine and stone equipment, raw materials are mainly granite, limestone, basalt, pebbles, and a certain hardness stone, after the vibrating feeder, jaw crusher, impact crusher, sand making machine, vibrating screen equipment crushing and screening to the required level.

Machine made sand by its own characteristics of the decision, all aspects of its applications are superior to ordinary natural sand. The degree of the thickness of the sand is a different size of sand mixed with the average degree of thickness. Generally, coarse sand, medium sand, fine sand. The sand particle size distribution refers to the mix proportion of sand size particles. The porosity of the sand depends on the particle size of sand material at all levels with Level with a good sand, not only can save cement, but also improve the density and strength of concrete and mortar. Generally, coarse sand, medium sand, fine sand.
Machine made sand has been a great help to alleviate the stone shortage in engineering construction, and become the backbone of a project stone production.
