What machines are needed to break stones into sand?

To break stones into sand, you will need the following machinery:

1. Jaw crusher: This is used to crush large stones into smaller pieces.

2.Cone crusher : This is used to further crush the stones into smaller particles.

3. Impact crusher: This is used to break the stones into sand by throwing them against a hard surface at high speeds.

4. Vibrating screen: This is used to separate the sand from the larger particles.

5. Belt conveyor: This is used to transport the stones and sand between the different machines in the production line.

Additionally, you may need other machinery depending on your specific needs, such as a washing machine to remove dust and dirt from the sand, or a fine sand recovery machine to recover fine sand that would otherwise be lost.
