Sand is widely used in such fields as agriculture and construction. It is also used in aquaria as a base material for reef tanks and in the creation of sand animation and sand casting. In recent decades, some cities even produce an artificial beach with sand to attract visitors and to improve the urban landscape. Therefore, the market demand for sand has increased steadily over the years. However, the main sources of sand— natural sand and gravel extraction—are limited and restricted by local governments. Therefore, manufactured sand, an alternative of natural sand, has become increasingly popular for both consumers and sand manufacturers.
Quality product ensures high commercial value. By using advanced sand processing equipment, the percentage of waste can be vastly reduced. More and more sand manufacturers have realized that an integrated sand solution can not only improve production efficiency but also lower the percentage of waste. Some customers may require that the diameter of the manufactured sand should be less than 16mm and the allowed percentage of by-products may be as low as 3%. Therefore, specialist knowledge about sand crushing and sand washing as well as advanced sand solution is essential to the production of quality manufactured sand.
Such equipment as vibrating feeder, impact crusher, and sand washer is widely used in the production of manufactured sand. Jaw crushers are used to crush a variety of materials ranging from rocks and recycled iron. Marked by high durability and excellent crushing performance,jaw crusher is well adapted to deal with almost every application, even the hardest materials, in any demanding environment. In general, a jaw crusher is mainly composed of a fixed crushing jaw and a moveable jaw. The two jaws constitute a wedge-shaped crushing zone so that such materials as rocks and sand can be crushed in the zone. Controlled by an eccentric shaft through a toggle plate system, this crushing zone rolls in a centrifugal manner.
If operated in a correct way, a sand washer can turn low-value dust into quality products that can be used in the making of concrete and asphalt. In this way sand manufacturers can boost their profits easily and ensure that the customers will get high-quality sand with a stable grading curve. Cutting-edge sand washer is equipped with an adjustable wedge system which is maintenance-free and powerful. Toggle plates exert forces on all sides and adapt to the movement of sand. A special lubrication mechanism ensures that the machine can work efficiently all the time. In this way, an advance sand washer guarantees the production of sand in accordance to the requirements of customers. Such parts as bucket wheels and screw classifiers in old sand washer models are replaced by a flexible wedge system. Thus the maintenance cost is drastically reduced and the time for sand processing is significantly shortened.
