Over the past few years, with the rapid development of domestic infrastructure construction, cities and new rural construction, the domestic sand and gravel aggregate crushing and mechanical  sand making machine   has also been developing fast, and the traditional sand and gravel aggregate was mainly manufactured by natural sand.

In recent years, with the constant construction of engineering projects, the demand for sand and gravel aggregate is increasing constantly and the quality requirement is improving unceasingly. The finished mechanical sand and gravel produced by mechanical sand making equipment and stone equipment of  Zenith Mining Machinery Co., Ltd., has such features as excellent grain shape, regular particle size, uniform specification and they can greatly improve the quality of high-quality projects.

In the production process of mechanical sand,  Zenith Mining Machinery Co., Ltd. changed the past simple crushing system of sand maker. After matching and combining many kinds of machines, the feeder, jaw crusher, sand maker, vibrating screen, sand washer and other equipment form a complete crushing system. The big stone enters the primary crusher-jaw crusher for primary crushing, the crushed materials enter the secondary crusher-sand maker for further crushing; and after this, sand with a certain particle size and specification will be gained to become the aggregate for infrastructure.

The preparation of artificial sand not only can meet the demand for lots of sand and gravel aggregates, but can realize higher quality compared with traditional sand and gravel aggregates. Therefore, in the sand making industry, the manufacture and usage of artificial sand have been very popular, and artificial sand has entered a new era.
