This high-efficiency tunnel slag recycling line engineered by SBM sets new benchmarks in material recovery. The project targets a stable output of 0-5-10-20-31.5mm sized aggregates and fine manufactured sand tailored for batching plants—built on a water-based, eco-conscious system that elevates both environmental and economic returns.
Online ChatThe pressure’s real—urban expansion, stricter waste codes, and a shift toward sustainable builds are rewriting the rules. Contractors and developers aren’t just *asking* for precise, reusable materials—they *need* them. They demand equipment that speaks quality, not compromise.
This setup was born from that very need—to convert 200TPH of tunnel leftovers into consistently graded sand and gravel fit for concrete mixing stations. Why settle for average when circular economy models require precision?
SBM didn’t win this project on brand name alone. They proved themselves with on-ground evaluations, performance trials, and a boots-on-site mentality. What clinched it? Their responsiveness, experience, and localized service deployment. No guesswork. Just results.
The incoming tunnel spoil gets its first cut with the PEW Jaw Crusher, ideal for rough duty material reduction. Downstream, HPT Multi-cylinder Hydraulic Cone Crusher handles size refinement with stunning accuracy, delivering that all-important 0-5-10-20-31.5mm spread.
And no, it’s not just dry dust flying around—this process leverages wet screening and scrubbing systems to keep impurities in check. With a tight loop water reuse design, no drop goes wasted, and there’s zero air pollution. It’s automation with conscience.
Crushing tough slag? Not a problem. CI5X Impact Crusher stands out with solid throughput and reinforced durability. Vibrating feeders like F5X Series and fine-tuned screens from the S5X Vibrating Screen series maintain smooth feed flow and grading uniformity.
SBM tech doesn’t just “work”—it works smart. Vibration absorption tech boosts sand quality. Plus, custom layout engineering maximizes every square meter, while special wear-resistant linings halve maintenance frequency. Who’s got time for downtime?
The facility isn’t just a steel-and-stone project—it’s a local economic engine. More jobs, less landfill reliance, and a serious nudge toward raw material regeneration. Data don’t lie—aggregate gradation hit every required target. Mixing plant feedback? Glowing.
And we’re just getting started. This same process model can pivot toward handling steel slag, power plant residue, or construction debris. With SBM’s ongoing support—training, upgrades, site check-ins—future-proofing isn’t wishful thinking. It’s already baked in.
Let’s ask it straight: Can your existing system handle high-moisture slag without choking? Can it grade across five specs without fail? Can it scrub clean, reuse water, and stay within emission rules? If the answer’s “maybe,” it’s already a “no.”
SBM brings battle-tested machines, real-world experience, and ironclad confidence. This isn’t theory—it’s working reality. The 200TPH line is living proof that advanced recycling is not a dream, it’s the standard. Ready to upgrade?
