What are the advantages of river pebble sand making?

Learn about river pebbles

River pebble is a silicate mineral with hard texture, wear resistance and stable chemical properties. Natural river pebble ore is produced into river pebble after a series of processes such as crushing, sand making, and screening. River pebble is an important Industrial mineral raw materials are widely used in water conservancy and hydropower engineering, high-grade highways, expressways, high-speed railways, passenger lines, bridges, airport runways, municipal engineering, high-rise building sand production and stone shaping. River pebbles are also widely used as aggregates for concrete. In recent years, the high-quality machine-made sand processed from river pebbles has also been affirmed and recognized by manufacturers with high standards!

In addition to river pebbles, granite, limestone, quartz sandstone, basalt and even construction waste can all be used to process machine-made sand. Why are river pebbles still so popular? What are its main advantages?

1. River pebbles are widely distributed, rich in resources, easy to mine and low in mining cost, and can meet large-scale production needs.
2. River pebbles are hard rocks, and their Platts hardness grades are generally 2-3, and the hardness coefficient is f=10-15. They are hard in texture, strong in compression resistance, wear resistance and corrosion resistance.
3. River pebbles are used as raw materials for processing machine-made sand. The amount of stone powder in the production process is relatively small, and the material is stable, with good performance, and the quality of the finished product is easy to control.
4. The machine-made sand made of river pebbles has excellent quality and stable performance. It is the preferred construction sand for infrastructure such as high-rise buildings, highways, municipal engineering, water conservancy and hydropower, and bridges.
