Customer

A top global mining equipment manufacturer, known for engineering some of the world’s largest and most powerful mining machinery, supplying heavy-duty equipment to critical mineral extraction operations across continents.

The Challenge: Removing Rust Preventive Oil from Massive Machine Parts

Mining equipment operates under extreme conditions, and corrosion protection is non-negotiable. Our customer, renowned for building large-scale mining machines in modular segments, faced a major obstacle during final assembly:

• These machine parts, made from mild steel (to avoid excess weight), are coated with rust preventive oil for 6–8 months during the production and storage timeline.
• Before assembly, this thick, long-settled layer of oil had to be completely removed to ensure weldability, safety, and performance.
• The customer’s team relied on manual Scotch-Brite scrubbing, which was labor-intensive, inconsistent, and ineffective on hard-to-reach surfaces, especially inner diameters and crevices.
• The process was not only time-consuming and physically draining, but also left behind oil residues, posing quality risks and delays on the production floor.

This was a job that demanded sheer power, precision, and intelligent automation — and Ralsonics stepped in with a custom-built powerhouse.

Ralsonics’ Tailored Solution: An Intelligent Heavy-Duty Cleaning System

Understanding the scale, complexity, and criticality of the task, Ralsonics developed a high-pressure, solvent-based washing machine engineered specifically for heavy industrial components. Our advanced system included:

• 16 bar High-Pressure Spray System: Delivering powerful jets of solvent from all directions to break down hardened rust preventive oil quickly and effectively.
• Rotating Mechanism: Ensured 360° coverage, cleaning every surface of the massive machine parts — even deep recesses and curved geometries.
• 4-Tonne Load Capacity: The robust structure accommodated extremely heavy components without compromising on accessibility or safety.
• ID Cleaning Nozzles: Specialized jets were provided for inner diameter cleaning, ensuring even concealed surfaces were left spotless.
• Pre-Heating Feature: Integrated heaters warmed the solvent to an optimal temperature, enhancing its cleaning performance before spraying.
• Advanced Filtration System: Captured and filtered contaminants to extend solvent life and reduce waste, improving sustainability and operating cost-efficiency.
• Smart Touchscreen Control Panel: Offered user-friendly operation with pre-programmed cleaning cycles, minimizing human error and increasing consistency.
• Fast Cycle Time: The entire cleaning process was completed in just 30 minutes, delivering unmatched speed and repeatability.

Results: Faster Assembly, Cleaner Parts, and Higher Throughput

Our high-performance cleaning system brought tangible, measurable improvements to the customer’s production workflow:

• Complete removal of rust preventive oil, with zero manual scrubbing required.
• Reduced cleaning time from hours to just 30 minutes per component.
• Improved operator safety and drastically lowered physical strain.
• Enhanced consistency and surface readiness for assembly, with no oil residue.
• Decreased solvent consumption through advanced filtration and reuse.
• Boost in throughput, helping the customer meet tight delivery timelines for their global mining clientele.
