River pebble crushing and sand making process and equipment list

The river pebble crushing and sand making production line mainly includes crushing, sand making, screening, feeding, conveying, sand washing and control system, etc. Today, I will share with you the common configuration scheme and equipment list of river pebble crushing and sand making production line:

1.Crushing equipment configuration

Primary crushing:

The jaw crusher is used as the first stage crushing equipment, which has strong processing capacity and can effectively crush large pieces of river pebbles to a particle size suitable for secondary crushing. The jaw plate is made of high manganese steel, which has strong wear resistance and meets the crushing needs of hard materials.

Secondary crushing:

Cone crusher or impact crusher (select according to the specific material hardness and shape) is configured to further crush the primary crushed material to a smaller particle size, providing ideal raw materials for subsequent sand making. Cone crusher is suitable for hard materials, while impact crusher has better crushing effect on medium hardness and soft materials.

2.Sand making equipment configuration

Sand making machine: Use high-performance impact sand making machine (such as VSI sand making machine), which adopts the principle of stone hitting stone or stone hitting iron to shape and make sand for finely crushed river pebbles, and produce machine-made sand with beautiful grain shape and reasonable grading. Its adjustable speed and feed amount ensure stable production efficiency and product quality.

3.Screening equipment configuration

Vibrating screen: Configure multi-layer vibrating screen to finely screen the materials after crushing and sand making, and separate products of different particle sizes. The vibrating screen adopts wear-resistant screen to ensure the screening rate and service life. At the same time, the screen aperture can be adjusted according to needs to flexibly control the product particle size range.

4. Feeding and conveying configuration

Feeder: Use vibrating feeder or plate feeder to ensure that the material enters the crusher evenly and continuously, avoiding equipment blockage or overload caused by uneven feeding.
Conveyor belt: The whole line is equipped with wear-resistant and corrosion-resistant conveyor belts to efficiently and stably transmit materials between each process, reducing losses and pollution during material transportation.

5. Sand washing equipment configuration

Sand washing machine: equipped with a bucket sand washing machine or a spiral sand washing machine to clean the materials after sand making, remove impurities such as soil and stone powder on the surface, and improve the cleanliness and quality of the sand. The sand washing machine has the advantages of large processing capacity, high cleaning degree and low water consumption.

6. Control system

PLC intelligent control system: adopts advanced PLC programmable logic controller to realize automatic control of the production line. The system has functions such as remote monitoring, fault alarm, and automatic adjustment of parameters to ensure the stability and safety of the production process, while reducing labor costs and improving production efficiency.

7. Auxiliary equipment

Dust removal equipment: equipped with high-efficiency dust removal equipment such as bag dust collector or pulse dust collector to collect and treat dust in the production process, reduce environmental pollution, and ensure the safety and cleanliness of the production environment.
Noise reduction facilities: soundproof the main noise sources such as crushers and sand making machines, install silencers or shock absorbers to reduce the noise during equipment operation and reduce the impact on the surrounding environment.

Storage and loading equipment: Set up a finished sand yard and loading equipment (such as a loader or bulker) to facilitate the storage and transportation of finished products.
The above is the common configuration plan and equipment list of river pebble crushing and sand making production line. The specific equipment model and quotation should be determined according to actual needs. If you have any questions in this area, you can consult us for details!
