How to solve the high mud content of sand and gravel

To solve the problem of high mud content in sand and gravel, several measures can be taken:

Improve Cleaning Process

Install more powerful cleaning equipment to increase the cleaning efficiency of sand and gravel. This can effectively remove the mud attached to the surface of sand and gravel particles.

Use Flotation Technology

according to different physical and chemical properties of mud and sand, the flotation process can separate mud from sand and gravel particles. This technology can effectively remove the mud content in sand and gravel.

Control the Source of Raw Materials

Strictly control the quality of raw materials, ensure that the raw materials used for sand and gravel production are clean and free of mud.

Increase Water Content of Sand and Gravel

appropriate increase in water content can help to separate mud from sand and gravel particles, reducing the mud content in sand and gravel.

Improve the Production Process

Adjust the parameters of the production process to reduce the mud content in sand and gravel. For example, reasonable selection of crushing equipment, reasonable matching of crushing process, etc.

In order to achieve a good desilting effect, the process design of the production line should adopt “double desilting”, that is, the small particles should be screened out before the first crushing, and the size of the screen should be controlled at 20-40mm.

Considering that the quality of the primary sand meets the technical requirements for the use of concrete raw materials, a powder separator should be installed on the finished product belt of the primary sand.
