For mining EPC projects, the real test of equipment reliability rarely ends at factory manufacturing - it unfolds on‑site, where unexpected structural obstacles, harsh environmental conditions and installation deviations constantly impact equipment startup.
Recently, as part of PRS's one‑stop EPC service, our engineering team completed the second‑round on‑site commissioning of a Cathode Stripping Machine (CSM) in Southeast Asia. We carried out full electrical wiring, sensor calibration, insulation and grounding checks, plus hydraulic‑pneumatic piping debugging, with core targets of mechanical optimization, safety validation and pre‑power‑on readiness.
Unlike standard factory testing, real‑world site conditions often differ greatly from design drawings. A critical issue emerged during hydraulic system installation: a large on‑site steel beam blocked the pre‑planned routing path for hydraulic oil pipes, preventing standard installation and risking poor maintenance space and unstable hydraulic performance. Instead of forcing the original layout, our team conducted targeted on‑site re‑engineering. We designed a downward‑extended steel support structure at the hydraulic station to bypass the beam, then replaced short original hoses with longer customized ones to match the new pipe routing. The revised hydraulic layout eliminated structural interference entirely and passed strict pressure and leak‑proof tests.
Adapting to Southeast Asia's humid, dusty mining environment was another key focus. Ordinary non‑waterproof connectors and standard cables behind the water tank posed long‑term leakage and short‑circuit risks. Our team upgraded these components with fully waterproof alternatives, standardized copper bar grounding layouts, and reserved extra terminal and wiring space inside pneumatic cabinets for future maintenance, greatly boosting the equipment's environmental adaptability.
We also fixed installation deviations in a timely manner, correcting misaligned positions of three conveyor motors and unifying parameters across design drawings, BOM lists and physical equipment, to avoid future operational confusion. After finishing all mechanical and electrical optimizations, we performed comprehensive pre‑power‑on tests covering insulation resistance, grounding safety, phase consistency and short‑circuit checks. All 11 onboard motors achieved insulation resistance above 550 MΩ, fully meeting startup standards.
Throughout the project, our engineers maintained smooth cooperation with local on‑site teams, sharing operational experience and adjusting progress together. Local partners highly recognized Chinese‑manufactured mining equipment for its cost‑effectiveness, stable performance and strong adaptability to tough mining conditions.
This commissioning project highlights PRS's strength in on‑site problem‑solving and detail‑oriented service. For cathode stripping lines, long‑term stable operation hinges on tackling small but critical on‑site challenges in advance. By addressing structural conflicts, environmental adaption risks and installation inconsistencies, we eliminate hidden failures before formal production, delivering reliable EPC solutions for global mining clients.
