Mining Spare Parts & Wear Consumables

Using low-grade or non-alloyed wear parts results in rapid abrasion, uneven crushing gaps, trunnion bearing vibration, and catastrophic pump casing blowouts.

Our spare parts catalogue features premium wear alloys: 27% high-chromium white irons for extreme abrasive slurry pumping, high-manganese steel (Mn18Cr2 / Mn22Cr2) for impact crushing, and high-purity polyurethane for hydrocyclones.

Every spare part is catalogued against the installed plant asset register (System 9) to ensure 100% mechanical interchangeability and predictable replacement scheduling.

Alloy Hardness Rating: Up to 65 HRC (High-Chromium White Iron)
Manganese Toughness: Mn18Cr2 / Mn22Cr2 (Work-Hardening Crusher Plates)
Dispatch Lead Time: 24 – 48 Hours (Ex-Warehouse for In-Stock Spares)
Asset Traceability: System 9 Mapped (Direct Equipment Linkage)

Frequently Answered Engineering Questions

Direct technical guidance regarding specifications, implementation, and regulatory compliance.

Are Green Ngoria spare parts compatible with major international equipment brands?

Yes. We supply direct-fit, precision-manufactured wear parts for Warman, Metso, Sandvik, FLSmidth, and Chinese-manufactured mining equipment.

Do you offer emergency spare parts delivery for plant breakdowns?

Yes. For critical in-stock spares (impellers, pump seals, contactors, carbon screens), we arrange direct hot-shot road delivery across Kenya within 24 hours.

Can you supply custom-cast crusher plates for obsolete or custom machinery?

Yes. Our engineering department can take 3D laser scans or physical patterns of your existing worn liners and manufacture custom manganese or alloy castings.
