What are the advantages of machine-made sand and natural sand?

Which is better, mechanical sand or river sand? Everyone has a steelyard in our hearts. We only use data to speak. According to the statistics of the National Sand and Stone Association, 75% of the construction, highway, and water conservancy industries in the country use mechanical sand. Now let's analyze the "six aspects" of which mechanism sand and river sand are better:

First, the "sandwich" of sand made by machine sand, 6 advantages become the focus
1. Granularity of finished product: The finished product of machine-made sand processed by sand-making equipment is cubic, with high uniformity and strong adhesion to aggregates; river sand grows naturally, and the surface of the river is washed away by the river, showing a smooth and smooth surface.

2. Stone powder content: The stone powder content of the machined sand is controlled at about 3%, 5%, and 7%, with different quality contents. Although the stone powder content is high, the sand can be washed and washed to obtain a good machined sand. The stone powder content of sand is generally between 1% and 2%, and the purity is high.

3. Ruggedness and practicality: The machined sand is crushed and has a low solidity. However, if the sand making equipment is selected according to different materials, the machined sand with good quality can also be achieved. The sex is very good, the use effect is lasting.

4. Production time: The production of machined sand is very simple. A single production line can produce a large amount of machined sand with a few equipments; river sand is formed naturally, the process is long, and resources are scarce.

5. Acquisition cost: The production mechanism of sand is only a high investment cost in the early stage, but the advantages outweigh the disadvantages in the later stage, and it will not be affected by the weather. The production line will have a long working cycle. taller and taller.

6. Investment prospects: 75% of the industries need to use sand and gravel, the demand is large, and the mechanical sand is facing the wind; river sand mining has many restrictions, and investment needs to be cautious.
