Expert System For Optimization Of Cement Mills

Summary: The milling process in cement plants is extremely energy-intensive, accounting for nearly 45 % of the overall electrical energy requirements. Siemens has designed an expert system which uses actual plant data to make precise predictions about quality parameters for a production plant, and which can be integrated into the existing PCS-7 control system with no additional hardware.

May 18, 2011 The FLC is optimized by GA for varying nonlinearity and set point in the plant. The proposed control algorithm was studied on the cement mill simulation model and with a real cement mill model using MATLAB and Simulink environments. Parameters of the simulation model were set up based on the actual cement mill characteristics.

What Does A Cement Plant Of The Future Look Like? (Part 2)

Dec 01, 2017 3) The cement mill grinds the clinkers to an appropriate heat to produce cement. Each step is critical but the final step is where the magic happens. Grinding to perfection. In the final step, the cement mill grinds the clinkers using horizontal ball mills. The ball mill has two rotating chambers with ceramic balls that grind the clinkers.
