Can tailings/construction site crushed stones be processed into sand? Machine made sand equipment

Yes, tailings and crushed stones from construction sites can be processed into sand using machine-made sand equipment. This process is known as sand manufacturing, and it involves using crushing and screening machines to produce artificial sand from these materials.

Here's a typical equipment configuration for a machine-made sand production line:

1. Feeder: A vibrating feeder or conveyor belt to control the flow of tailings or crushed stones into the production line.

2. Primary crusher: A jaw crusher or impact crusher to process the raw material into smaller particles.

3. Secondary crusher (optional): A cone crusher or vertical shaft impact crusher for further crushing, if necessary, depending on the desired final particle size.

4. Screening equipment:

* Vibrating screen(s): To separate the crushed particles into different size fractions. You may need multiple screens with different mesh sizes, depending on the desired final product specifications.

5. Sand washing equipment (optional): A sand washing machine can be added to remove dust and impurities from the crushed particles, ensuring a clean and high-quality final product.

6. Final product processing:

* Screened sand conveyor: To transport the washed sand to the final destination, such as a storage pile or loading station.

* Stacker or conveyor belt (optional): To create a 整齐的堆垛 or transfer the sand to a different location, if necessary.

7. Control and monitoring systems:

* PLC (Programmable Logic Controller) or other control system: To automate and monitor the entire production line, ensuring efficient and consistent operation.

* Sensors and instrumentation: To measure and monitor key process parameters, such as material flow, particle size, and machine performance.

8. Supporting equipment:

* Electrical and mechanical components: To power and maintain the production line, including motors, gearboxes, bearings, and other critical components.

* Safety systems: To protect operators and ensure safe operation of the production line, including guarding, emergency stop buttons, and other safety features.

When processing tailings or construction site crushed stones into sand, it's important to consider the type of material being processed, the desired final product specifications, and any environmental regulations that may apply. Consult with experienced machine-made sand equipment suppliers or manufacturers to ensure that the equipment configuration meets your specific needs and requirements.
