A gravel production line with an output of 200 tons per hour using gravel as the raw material

A gravel production line with an output of 200 tons per hour using gravel as the raw material typically involves the following equipment and processes:

1. Raw material storage: gravel is stored in a designated storage area or bin to ensure a constant supply of raw material for the production line.

2. Feeding: A vibrating feeder or belt conveyor is used to transport the gravel from the storage area to the crushing equipment at a controlled rate.

3. Crushing: The gravel is crushed into smaller particles using a jaw crusher or impact crusher. The crushing process typically involves two stages: primary and secondary crushing. The primary crusher reduces the gravel to a smaller size, and the secondary crusher further reduces the particles to the desired size.

4. Screening: After crushing, the gravel particles are screened to separate them based on their size. The screened gravel is divided into different particle sizes, and only the particles meeting the desired specification pass through.

5. Sand making: The gravel particles that do not meet the desired size requirement are sent to a sand making machine (such as a vertical shaft impact crusher or sand mill) to further reduce their size and create a finer grain size distribution.

6. Classification: The crushed and sanded gravel is subjected to classification using a separator or screen to separate particles based on their size, ensuring a uniform final product.

7. Washing and dewatering: To remove dust and dirt particles, the gravel is washed with water. After washing, the gravel is dewatered using a screw conveyor, belt conveyor, or vibrating screen to remove excess water.

8. Sand storage and packing: The finished gravel sand is stored in a silo or container for further processing or direct use. If required, the sand can be packed into bags or containers for easy transportation and storage.

9. Water treatment: A water treatment system is used to remove any pollutants from the water used in the washing process, ensuring environmental compliance.

10. Control system: A control system monitors and adjusts the parameters of the equipment to ensure optimal performance and product quality.

11. Maintenance and cleaning: Regular maintenance and cleaning of the gravel production line are essential to ensure its smooth operation and prolong its service life.

With an output of 200 tons per hour, the gravel production line can supply a large quantity of high-quality gravel sand for various applications, such as construction, concrete production, and infrastructure projects. The line's efficiency and productivity are crucial for meeting the demands of the construction industry and other sectors that require gravel sand materials.
