Alternate grinding of raw material and clinker

Gebr. Pfeiffer, Inc., the US-based subsidiary of Gebr. Pfeiffer AG, Kaiserslautern, was recently awarded a contract to supply an MPS Mill for the cement plant of Cementos San Marcos SA. The plant is located near the company’s limestone quarry in Cobo Lloreda, north of Yumbo, Colombia. The unique advantage of the MPS Mill is that it can alternately grind both raw material and clinker, depending on the company’s changing needs. This feature allows Cementos San Marcos to increase plant efficiency while reducing their overall mill investment costs.

Cementos San Marcos SA is a newly established company owned by a consortium of the following companies: The ­Family Otoya Dominguez, The Siderurgica de Occidente SIDOC S.A. and CSS Construcciones SA. The grinding plant will also save on transportation costs, giving them a competitive advantage, due to the close proximity to the existing mine. The project will generate approximately 210 direct jobs with an estimated production capacity of 200 000 t/a and is scheduled to be up and running within 24 months, with delivery of the MPS Swing Mill taking place in 12 months.
