What equipment is needed for river dredging sand and gravel processing?

After the river channel dredging work is completed, the sand and gravel resources from the dredging are of great utilization value.It contains natural river sand, as well as river pebbles, pebbles and other stones.Natural river sand has excellent quality and large market demand, while stones such as river pebbles and pebbles have high silica content and high hardness, and can be processed into high-quality mechanism sand and gravel.The following is a detailed introduction to the equipment required for processing.

Pre-screening, separation of high-quality river sand

In the first step of processing, the raw materials for dredging sand and gravel can be pre-sieved to screen out natural river sand of good quality to meet the market demand for high-quality river sand.

Crushing production line to create mechanism sand and gravel

Vibrating feeder: As the starting link of the production line, the vibrating feeder is responsible for conveying the stone evenly and stably to the crusher.It can ensure that the subsequent crushing work is carried out in an orderly and efficient manner, and avoid problems such as idling or clogging of the crusher due to uneven feed.

Jaw crusher: In coarse crushing operations, jaw crusher can be called the “main force”.It is suitable for coarse crushing of various types of ore rocks, and its strong crushing capacity can crush large stones to medium size at once, laying the foundation for subsequent processing processes.

Hydraulic cone crusher: For the medium and fine crushing of high-hardness stones such as river pebbles, hydraulic cone crushers have obvious advantages.It adopts the principle of lamination and crushing, and with the help of the crushing effect between the stones, the impact and wear on the machine are greatly reduced.At the same time, it can significantly improve the particle size of the finished stone, reduce the content of needle-like stones, and improve the quality of mechanism sand and gravel.

Vertical shaft impact crusher: This equipment is mainly put into use as an integral sand making equipment.According to the principle of ”stone to stone“ and ”stone to iron", relying on the impact force between the stones, it can not only produce finished sand with good grain shape, but also has extremely high sand making efficiency and is widely used in sand and gravel production lines.

Screening and cleaning to improve the quality of sand and gravel

Round vibrating screen: In the treatment of sand and gravel after crushing, the round vibrating screen plays a key role.It can screen sand and gravel and grade them according to different particle sizes to meet diverse market needs.

Sand washing machine: If you expect to produce mechanism sand with higher purity, a sand washing machine is essential.Through cleaning, impurities on the surface of the sand and gravel can be removed and the quality of the mechanism sand can be improved.

Conveying equipment, connecting production lines

Belt conveyor: The belt conveyor runs through the entire production line and undertakes the task of conveying sand and gravel between the various sections.It closely connects the various equipment to ensure the smooth flow of materials and maintain the efficient operation of the production line.

Mobile crushing station: For some riverstone crushing operations that require frequent changes of work sites, mobile crushing stations are an excellent choice.It does not require the construction of a concrete foundation, is easy to install and dismantle, and has a rapid transition. It is especially suitable for sand and gravel processing projects with short construction periods and urgent materials, and provides great flexibility for operations.

Through the collaborative operation of these equipment, the sand and gravel resources dredged from the river can be fully utilized and transformed into high-quality building materials that meet market demand, so as to achieve a win-win situation of rational reuse of resources and economic benefits.
