Process characteristics of river stone crushing production line

River stone is a natural and excellent building material. After proper crushing and processing, it can be widely used in the production of building sand and concrete aggregate. Modern river stone crushing production line adopts a three-stage crushing process, which usually includes jaw crusher for primary coarse crushing, cone crusher for intermediate crushing and impact sand making machine for fine crushing and shaping. This configuration scheme can ensure that river stone materials are crushed efficiently while ensuring the excellent particle shape of the final product.

Key points for core equipment selection

Crushing equipment selection is the key to the entire production line. Liming Heavy Industry's PE series jaw crusher adopts an optimized deep cavity design, with higher crushing capacity and longer service life of wear-resistant parts; HPT series hydraulic cone crusher achieves high swing frequency and optimized cavity shape through the principle of laminated crushing, which significantly improves crushing efficiency; 5X series sand making equipment not only has both shaping and crushing functions, but also has the characteristics of low wear rate, which is very suitable for fine crushing of river stones.

Production line configuration needs to consider raw material characteristics and output requirements. Conventional configurations include vibrating feeder, jaw crusher (PE series), cone crusher (HPT series), sand making machine (5X series), circular vibrating screen (S5X series) and sand washing equipment. Such a combination can process 50-500 tons of river stone materials per hour, adapting to production needs of different scales.

Performance advantages and application range

The outstanding advantages of modern river stone crushing production lines are: high degree of automation, low operating cost, high crushing rate, energy saving and environmental protection. The finished sand and gravel have the characteristics of uniform particle size, good particle shape and reasonable grading, which fully meets the national standards for building sand. In particular, the design equipped with dust prevention equipment meets the current requirements of green and environmentally friendly production.

The river stone products processed by this type of production line are widely used in hydropower engineering, highway, railway construction, municipal engineering and real estate construction. By adjusting the equipment parameters, you can obtain crushed stone products of different specifications such as 5-10mm, 10-20mm, 20-31.5mm, as well as high-quality machine-made sand to meet various construction needs.

EPC general contracting service advantages

For large-scale river stone crushing projects, the EPC general contracting model provides a complete solution. From planning, selection to construction and trial operation, a professional team is responsible for integration to ensure clear responsibilities and a fixed total price. For example, the 300T/H river pebble sand making EPC project in Chizhou, Anhui, adopts a three-stage crushing process and ultimately produces three specifications of finished products: 0-5mm, 5-10mm and 10-31.5mm, which fully demonstrates the efficiency and reliability of the EPC project.
