Electrochemical salt spray equipment: accurately evaluate material anti-corrosion effects

At BOTO GORUP, we’ve set our sights on the mining and mineral processing sector—an industry that powers global economies with its extraction of critical resources, yet operates in some of the harshest, most corrosion-prone environments on Earth. Our mining-specific salt spray test chambers are engineered exclusively to validate the corrosion resistance of heavy-duty equipment and precision components, from mining truck hydraulic cylinders and drill bit casings to conveyor belt fasteners, underground sensor enclosures, and mineral processing plant pipelines. As mining operations expand into coastal salt flats, humid underground shafts, and regions with de-icing salts (for winter surface mining), traditional salt spray testing systems have failed to replicate the unique, brutal stresses these assets endure: extreme mechanical impact (from rock loads), abrasive dust wear, chemical exposure (flotation agents, acids, and alkalis), and cyclic temperature swings (sub-zero winters to scorching summer heat). Our mining-focused chambers fill this critical gap with rugged, industry-tailored testing capabilities, empowering mining equipment manufacturers and operators to build durable assets, minimize costly downtime, and protect worker safety.
Through decades of collaboration with mining engineers, equipment designers, and site maintenance teams, we’ve identified the distinct corrosion hurdles that generic salt spray chambers cannot address—hurdles where failure risks production shutdowns, expensive repairs, and even workplace hazards. Mining truck hydraulic cylinders and wheel hubs face relentless salt mist (3.5–5% NaCl in coastal mines) paired with heavy mechanical loads (up to 300 tons per truck) and abrasive rock dust that wears protective coatings, leading to rust-induced seal failures and hydraulic leaks that halt operations for days. Drill bit casings and downhole tools are exposed to high-salinity groundwater (2–4% NaCl) and chemical drilling fluids (containing chlorides and sulfates) that corrode metal surfaces, reducing drill bit lifespan by 30–40% and increasing drilling costs. Conveyor belt fasteners and pulley systems in salt mines or coastal processing plants endure constant salt exposure and mechanical friction, with corrosion causing fastener breakage and belt misalignment that risks catastrophic spills. Underground sensor enclosures, critical for gas detection and structural monitoring, battle high humidity (90–100% RH) and salt-laden air, with corrosion short-circuiting electronics and compromising safety protocols. Generic salt tests ignore these synergies—they can’t simulate the abrasion-corrosion interplay of rock dust and salt, or the chemical aggression of mining fluids—and thus fail to predict real-world failures. These challenges demanded a testing system that merges salt spray exposure with mining-specific stresses, and we’ve engineered our chambers to deliver exactly that.
Early adopters of our mining-grade chambers have already seen transformative results that drive efficiency and cost savings. A leading global mining equipment manufacturer used our Abrasion-Chemical-Salt Module to resolve corrosion issues in its mining truck hydraulic cylinders, which had failed after 6 months of use in coastal iron ore mines.
At BOTO, we’ve designed our mining-grade chambers to be as rugged and adaptable as the industry they serve, with standard configurations shipping within 6–8 weeks and fully customized systems (tailored to specific mining environments, equipment types, or chemical exposures) delivered in 10–16 weeks. We offer complimentary corrosion risk assessments for qualified mining equipment manufacturers and operators, including a 72-hour demo test of critical components to identify vulnerabilities before deployment. Backed by our global support network with hubs in North America, Europe, and Australia—key mining regions—our dedicated mining testing specialists provide localized guidance on standard alignment, site-specific simulation, and technical troubleshooting, ensuring our clients get the most from their investment.
We believe that mining’s critical role in powering the world demands equipment that can withstand its harshest environments—and that corrosion should never be a barrier to safe, efficient operations. Our mining-specific salt spray test chambers merge industry-tailored stress simulation, rugged engineering, and regulatory compliance to address the unmet corrosion testing needs of the sector, enabling our clients to catch failures early, extend equipment lifespans, and reduce maintenance costs. As the mining industry evolves to meet global resource demands while prioritizing safety and sustainability, we remain committed to developing testing solutions that support resilient, durable equipment—protecting investments, ensuring worker safety, and keeping critical operations running smoothly.
