What Is the Difference Between Artificial Sand and Natural Sand?

In recent years, the demand for sand and stone is huge in the construction market. The contradiction between supply and demand of sandstone aggregate is especially prominent. The market of artificial sand is showing great potential and vitality. The replacement of natural sand by artificial sand has become the inevitable trend of the industry development. So what is the advantages and characteristics of artificial sand compared with natural sand such as sea sand,river sand,etc.?

First, there are obvious differences between the artificial sand and the natural sand in appearance. The artificial sand is the sand and stone material crushed by sand making machine and other professional sand making equipment, it has the characteristics of sharp angle and rough edges compared with the natural river sand. The river sand is dug directly from the river, so it is mixed with small pebbles and fine sand. These small pebbles are scoured by the river for a long time, and the edges and corners are mellow and full. Yet the artificial sand produced by sand stone equipment is more sharp and clear, and the strength is worse than the river sand.

Second, the high powder content is one of the important characteristics of the artificial sand which is different from the natural river sand. We should separate the powder content of the artificial sand from the mud content of the natural sand.

Third, they have certain differences in the firmness, adhesion and compression. The particle size of the artificial sand is irregular, they often have better adhesion, more compression, and longer service life while worked with cement and other structures.

Fourth, they have obvious difference in the structure and fineness modulus. The raw material of artificial sand is generally selected and the material is homogeneous and stable, mineral composition and chemical composition are consistent with raw materials, and are not as complex as natural sand. The fineness modulus of the artificial sand can be artificially controlled by the production process, and the production is organized according to the requirements of the user, which can not be done by the natural sand.
