Cement Plant Computer---Success or Failure?

The progress and current status of process control computer applications in current plants in the United States are reviewed. The future role of digital computers is projected, including an analysis of the potential of mini-computers. While computers have not been a resounding success in the cement industry, measurable progress has been accomplished. Kiln-cooler control will continue to be hampered by lack of programmable operating parameters and lack of effective sensors. Raw material blending programs will continue to be the most successful area of computer control in cement plants.
