Along with the increasing demand with sand, combined with the natural sand resources is limited, the promulgation of the national natural sand series environmental protection measures, make great demand of sand and gravel aggregate appeared a serious imbalance between supply and demand. The emergence of alternative for this type of mechanism sand, all to the construction industry and civil engineering construction industry in our country to bring the Gospel
The appear of manufactured sand is a good solution to the emergence of demand for manufactured sand tense situation, as more and more manufacturers of mining quarrying sand rise, China's Manufactured Sand mainly from the sales of both domestic and export development, one of the main points to domestic serves regional sale, mainly in the construction industry, road construction, subway, construction and other industrial areas use; Second exported mainly for sand and gravel resource-starved areas, the high rate of return on any other industry can not be compared.
Mechanism of sand production in terms of supporting system sand machine production line use, generally are prepared according to the requirements of production enterprises, vico heavy industry with many years of equipment production, sales manufacturer, through years of experience, factory general sand production scale tend to be small, medium, large several categories. Mainly use the equipment to generate process roughly: (silo) - > vibrating feeder - > mandibles crusher - > counterattack crusher sand machine (optional) - > system - > vibrating screen - > sand washer - > sand (finished product), and among all devices are connected by chute or belt conveyor, etc.
Furthermore, after Sand making machine equipment were installation and commissioning smoothly, in addition to routine maintenance, maintenance, construction the long-term benefits of production equipment, it is also the granite do mechanism sand market feasibility analysis of important factors.
