SmartMill Control is a modern control system for grinding plants. The Fuzzy-Expert-system performs much better than the “classical“ closed loop controls (PID) or even rule based expert systems. SmartMill Control enhances efficiency and durability of grinding systems significantly. A single control block can take several inputs and outputs into account,leading to much better control results. Smooth and stable operating conditions and optimisation of throughput are primary goals of control startegies. SmartMill Control is based on highly developed software tools and building blocks. Data exchange to the process / grinding plant is performed by means of standardized industrial interfaces. Consistent and consequent usage of open system interfaces enables easy connection to all automation systems being used in todays‘ cement industry .Due to the highly modular design of SmartMill Control investment is kept low.
