Cement plant increases production by 20 %

St Marys Cement based in Ontario/Canada is a part of the Brazilian building materials supplier, ­Votorantim Cimentos, and produces a variety of cement for widely differing purposes. To meet ­demand, the producer is expanding its Charlevoix, Michigan production facility, with the addition of various mills for cement and coal, as well as clinker kilns and cooling systems. Modernization of the existing raw mill was also on the agenda. As part of the 130 million US$ investment project, Siemens was commissioned to supply over 12 million ­US$ worth of electrical equipment and a complete engineering solution for the ­cement plant. Siemens successfully engineered diverse equipment from different vendors.

For the plant modernization and expansion, ­Siemens supplied not only medium-voltage drives, but also the entire process automation and instrumentation: from the Cemat PCS7 process control system through medium-voltage switchgear type GM-SG-AR (five to 15 kilovolts) to modular custom pre-produced substations known as Ehouses for a fast, reliable energy supply. The Siemens solution will enable St Marys Cement not only to reduce the costs of project completion, but also to minimize the risk of a power outage. By implementing this expansion and modernization program at the cement plant, St Marys Cement plans to increase its previous production capacity by 40 % from 1.4 million t to 2 million t annually.
