CEMEX produces and distributes cement, ready-mixed concrete, aggregates and associated building materials in more than 50 countries. The company currently employs more than 57,000 people throughout the world. With an annual sales volume of more than US$ 21 billion, CEMEX is one of the three biggest cement manufacturers in the world (position as of 2008).
The modern-day CEMEX HüttenZement GmbH in Dortmund has trusted in ABB technology for production control since 1982. Procontic DP800, Master Piece 200, Master-View 800 and Advant OCS were the control systems which ensured a smooth production flow.
Modernization has culminated in the migration of the Advant OCS operating level to ABB’s System 800xA. For the analysis, ABB’s LifeCycle IndexTM was used to determine the productivity status and to identify potentials for improvement in the areas of technology, plant supervision and productivity management.
The migration to the new system has helped to reach the goal of reduced down times and increased availability.
ABB technology was used for the modernization of the control engineering systems of the milling and mixing plant. ABB supplied the 800xA control system as well as a new motor control center (MCC) for loading cement and an ACS800 frequency converter system for the roller press in Mill 7 with a motor power of 2x500 kW.
Scope of supply
- System 800xA with 13 client workstations
- ACS800 frequency converter with motor power of 2 x 500 kW
