How to process stone chips into machine made sand?

The process of crushing stones into machine-made sand mainly includes the following steps:

1. * * Pre treatment * *: First, clean the stones to remove surface soil and impurities. Then, by sieving, the stones are classified according to their size.

2. * * Crushing * *: Send the classified stones into a crusher for crushing. Crushers can choose from jaw crushers, cone crushers , or impact crushers . During the crushing process, the stones will be crushed into smaller particles.

3. * * Screening * *: The crushed stone particles are screened to separate sand particles of different sizes. Screening can be done using equipment such as vibrating screens or drum screens.

4. * * Cleaning * *: The screened sand particles may still contain dust and impurities, and need to be cleaned using cleaning equipment. The cleaned sand particles are cleaner and of better quality.

5. * * Drying * *: If necessary, the moisture in the sand particles can also be removed through drying equipment to meet the needs of certain special applications.

6. * * Packaging and Storage * *: Finally, pack and store the processed machine sand for use.

In this process, it is necessary to select appropriate crushing and screening equipment and processes based on actual production needs and the characteristics of the stones, in order to ensure the quality and yield of the mechanism sand. At the same time, attention should also be paid to environmental protection and energy conservation, and efforts should be made to minimize energy consumption and pollution during the production process.
