Natural sand is formed under certain natural conditions. Rock particles with a particle size of less than 5 mm are generally divided into river sand, lake sand, mountain sand, and sea sand. Among them, river sand and lake sand are used in large quantities.

With the increasing shortage of natural sand such as river sand, the application of artificial sand is becoming more and more extensive. The large-scale use of artificial sand is not only due to the requirements of ecological and environmental protection, but also due to the advantages of artificial sand itself, which makes the performance of artificial sand in actual use not inferior to natural sand.

 

The raw materials of artificial sand are usually granite, basalt, river pebbles, limestone, construction solid waste, etc. The hardness, corrosion resistance and other parameter values ​​of different raw materials are different. For example, granite belongs to a rock with a higher hardness coefficient, and limestone belongs to a rock with a softer texture.

 

Although the finished sand made from different raw materials will be different, overall, artificial sand has great advantages:

 

1. The quality is guaranteed, the source of raw materials is fixed, and the mechanized production line is produced. The particle shape and particle size can be adjusted and controlled according to needs, ensuring the stability of product quality.

 

2. The finished product is of good quality, with low content of impurities such as soil, high surface energy and hydrophilicity, and complete gradation.

 

3. The raw materials are extensive, can be obtained locally, and can be produced using various mineral resources or even waste resources.

 

4. The price is advantageous. According to quotations from all over the country, the machine-made sand is about 20 yuan cheaper per ton than the river sand.

 

Among the many types of machine-made sand, river pebble machine-made sand has excellent quality and is very popular among market users.

 

The main chemical composition of river pebbles is silicon dioxide, followed by a small amount of iron oxide and trace elements such as manganese, copper, aluminum, and magnesium. The main characteristics of river pebbles are hard texture, compression resistance, and stable chemical properties.

 

In the process of sand production, river pebbles have relatively less stone powder content, stable material, and the quality of the finished product can be well controlled. Therefore, the machine-made sand processed by river pebbles has excellent quality and is widely used in the construction of water conservancy and hydropower, highways, high-speed railways, bridges, airport runways, high-rise buildings, etc. in the engineering field.
