Choosing the right crushing and sand-making equipment for sand and gravel aggregate production is crucial to project success. The following describes the equipment selection and process flow for a river pebble crushing and sand-making production line:

I. Project Overview and Equipment Selection

After in-depth market research and technical comparisons, the client decided to utilize a complete set of crushing and sand-making equipment provided by Shibang Group. This equipment includes a CS240 cone crusher, two HPT300 multi-cylinder hydraulic cone crushers, and two VSI5X9532 high-efficiency centrifugal impact crushers, forming an efficient and stable crushing and sand-making system.

II. Advanced Equipment Configuration Analysis

1. CS Series Cone Crusher: As the core equipment in the secondary crushing stage, the CS240 cone crusher, with its outstanding crushing capacity and stable operating performance, provides a uniformly sized intermediate product for subsequent processes. Its unique crushing chamber design and efficient crushing force distribution ensure thorough material pulverization and uniform discharge.

2. HP Series Multi-Cylinder Hydraulic Cone Crusher: Two HPT300 multi-cylinder hydraulic cone crushers installed in parallel form a closed-circuit system, further crushing materials larger than 31.5mm. This design not only improves crushing efficiency but also enables precise particle size control through a fully hydraulic control system, simplifying equipment maintenance and upkeep.

3. VSI5X Series New Sand Making Machine: Two VSI9532 sand making machines installed in parallel convert stone materials smaller than 10mm into high-quality machine-made sand with a size of 0-5mm. These sand making machines utilize an optimized deep-cavity rotor, significantly increasing material throughput and sand production efficiency. Their integrated design allows for flexible adjustment of the sand-to-gravel ratio to meet diverse market demands.

III. Process Flow and Equipment Advantages

The project's process flow is scientifically and rationally designed. River pebbles first enter the CS240 for secondary crushing, followed by screening to separate a portion of the finished product. Materials larger than 31.5mm are conveyed to the HPT300 multi-cylinder hydraulic cone crusher for further crushing, forming a closed-circuit cycle that ensures thorough crushing and particle size control. Stones smaller than 10mm are directly fed into the VSI9532 sand making machine for sand production, ultimately producing high-quality machine-made sand with a particle size of 0-5mm.

The advantage of Shibang Group's equipment lies in its comprehensive design services, which significantly reduces unnecessary investment. The use of advanced multi-cylinder hydraulic cone crushers and VSI5X sand making machines achieves laminated crushing with fine particle shape, precise and reliable full hydraulic control, and easy equipment maintenance. The VSI5X sand making machine, in particular, improves material throughput and sand production efficiency through its deep-cavity rotor and optimized design.
