Machine-made sand is a kind of raw material which is screened by crushing equipment, so the selection of crushing equipment should be very strict. Compared with the traditional sand machine, the efficient sand making machine can increase about 40% and run steadily, and the sand and gravel products are mostly cubic, needle-like materials and stone powder content are relatively small. It can be directly used in the current capital construction sand industry without redundant treatment.

In recent years, with the rapid development of the construction industry, the market demand for building materials has increased dramatically, and the quality requirements have become increasingly high. Because of its good hardness and stable chemical properties, sandstone is called high-quality building materials. However, natural sandstone is gradually replaced by machine-made sand, which has become an important raw material in the current sandstone aggregate market due to the prohibition of mining and the repeated outbreak of environmental protection.

From the raw material point of view, machine-made sand has a variety of mineral components to choose; in terms of quality, it has a high surface energy and hydrophilicity, and has a complete mix; the mechanized production mode ensures the quality stability and controllability of machine-made sand products. In addition, the production technology of machine-made sand has become mature, and has formed a systematic and large-scale, and the performance of machine-made sand can fully guarantee the production requirements of concrete and meet the safety standards. It has become the mainstream of social development. It not only solves the demand of building materials market, but also plays a certain role in the protection of natural environment.
