thyssenkrupp Polysius pre-engineers SMA Mineral 120 t/d EAC pilot in Mo i Rana

Key highlights
  • thyssenkrupp Polysius is executing pre-engineering for a 120 t/d Electric Arc Calciner (EAC) pilot plant in Mo i Rana, Norway.
  • SMA Mineral commissioned the work and SaltX Technology's EAC process will be integrated.
  • Design scope targets a multi-stage cyclone preheater with cyclone-flash cooling for preheating and cooling.
  • SMA Mineral funded material tests, supported by SaltX, to validate thermal behavior and inform the FEED.

Project and scope

thyssenkrupp Polysius was commissioned by SMA Mineral to perform pre-engineering for a flash calcination pilot using SaltX Technology’s Electric Arc Calciner (EAC) at Mo i Rana, Norway; the FEED-level work focuses on conceptual design and preliminary layout of preheating and cooling systems for a planned 120 t/d pilot.

Technical solution

Engineering targets a multi-stage cyclone preheater with cyclone-flash cooling adapted to site structural conditions and integrates the EAC process; the pre-engineering provides the technical basis for the pilot and potential future full-scale facility.

Material tests and next steps

SMA Mineral financed material tests, supported by SaltX, to assess thermal behavior inside the cyclone preheater under electric process conditions; test data will validate and refine key process parameters and feed into the FEED, supporting the ZEQL project goal of moving quicklime production toward fully electric, low-emission operation.
