Crusher Innovation Solves Traditional Project Challenges

Last year we were introduced by an existing client and partnered with the project team. The channel had long been silted, causing rising water levels and reduced capacity. Dredging produced large amounts of silt and hard bluestone. Traditional off‑site hauling and processing were expensive and environmentally unfriendly. The key was to process on‑site and turn waste into usable construction aggregates.

I. Project Preparation

Early on, the riverbed was heavily silted with mixed mud and stone. Conventional methods would require hauling out and then bringing back finished materials – costly and polluting. We proposed an on‑site crushing and screening solution. Given the high silt content and medium‑hard bluestone, we chose the SF‑380 impact crusher with a conveyor belt and an SS‑6518 inclined screen. A pre‑screening system on the crusher removes fines and mud, boosting efficiency by 30% and reducing jamming and wear. The crushed material then goes to the screening station, where multi‑layer decks separate 0‑5mm sand, 5‑10mm and 10‑22mm stone – directly usable for road base, concrete, and foundation work.

II. Crushing and Screening Equipment Performance – SF and SS Series Advantages

Over the 15‑month project, the equipment performed steadily.

• High‑efficiency crushing
  The pre‑screen significantly increased crusher throughput. The high‑power rotor and durable hammers continuously impacted the bluestone, breaking it to target sizes. Wear parts lasted longer than expected, solving the common problems of clogging and rapid wear, thus lowering operational costs.

• Precise screening
  Crushed material entered the SS‑6518 screening station, where multi‑layer screens accurately separated 0‑5mm, 5‑10mm, and 10‑22mm aggregates – all meeting production standards. These products supplied urban road and concrete works, turning previously useless waste into saleable materials.

• Capacity and stability
  The line averaged 3,500 tons per day, producing a total of 1.1 million tons. Despite rainy seasons and heat, downtime remained low and operation was consistent. The project manager said that previously he had to monitor every detail daily; with this solution, output was so predictable that he no longer needed to be on site every day.

• Mobility and noise control
  Since the project was in an urban area and required frequent relocation, the tracked, self‑propelled chassis followed the excavators easily across muddy or uneven ground. Night work sometimes was necessary, so we paid close attention to noise. Through structural design and soundproofing, we kept noise well below local limits, and no complaints were received. In fact, the distinctive machines often drew curious onlookers.

III. Win‑Win Benefits: River Remediation and Aggregate Production

• Ecological and engineering benefits
  On‑site processing eliminated the need to haul hundreds of thousands of cubic metres of material off‑site and back again. This saved significant transport costs and reduced carbon emissions.

• Economic benefits
  Within the 15 months, processing the river material alone generated nearly ¥10 million in direct revenue for the group, not counting savings from avoided aggregate purchases and haulage. After completion, both machines were cleaned and maintained – they looked nearly new, with only wear parts replaced, and could be redeployed to other projects with little value loss.

IV. Conclusion

This successful partnership demonstrates the combination of sound construction technique and high‑end equipment, highlighting the adaptability and cost‑effectiveness of the SF‑380D and SS‑6518 under complex conditions. The SS‑6518 has now been upgraded to the SS‑7018 for higher output and finer screening. We have established a long‑term strategic relationship with the client and will continue to provide suitable equipment for mining, recycling, and road construction projects.
