Sandvik Kitwe exciter refurbishment: uptime and spares gains for Zambian mines
Reviewed by Tom Sullivan

30 Second Briefing
Sandvik Rock Processing has commissioned an OEM exciter repair and refurbishment facility at its Kitwe service centre in Zambia, allowing mines to service vibrating-screen exciters locally instead of shipping units to South Africa. The workshop is initially dedicated to Sandvik’s installed exciter base in-country, with OEM tooling, procedures and test capability to restore units to original performance specifications. Shorter logistics chains and reduced turnaround times should cut screening downtime and spares holding, particularly for large multi-deck classification and dewatering screens.
Technical Brief
- OEM repair scope typically includes bearing replacement, shaft and housing inspection, re-machining and dynamic balancing of exciters.
- Refurbishment to OEM tolerances is critical to maintain designed stroke, frequency and screen acceleration levels.
- Localised exciter servicing particularly benefits large multi-slope and high-frequency screens with critical classification duties.
- Reduced exciter logistics enables mines to run leaner critical-spares strategies on screening circuits.
Our Take
Across our mining coverage, Sandvik Rock Processing’s recent African push has centred on aftermarket and life-extension offerings – from the Reborn crusher programme (16 Oct 2026) to breaker systems – so adding OEM exciter refurbishment in Kitwe fits a pattern of anchoring service capability close to high-utilisation plants rather than selling stand-alone equipment.
Taken together with the upgraded jaw crusher range completed in 2026 (1 Jul 2026 article), Sandvik’s investment in both new platforms and regional refurbishment capacity suggests a long-term strategy to lock in installed-base loyalty in African hard-rock circuits by tightening the link between OEM design and local service execution.
