Smart control system includes quality control system, computer control system, expert optimization system, cement auto-packaging system, bulk auto-control system, water treatment auto-system, smart control of compressed air station and un-manned control system of stacker-reclaimer. The implementation of smart control system will improve the time effectiveness of sample test, instantly track and adjust product quality, thus realizing the process quality traceability and creating a higher analytical ability and more efficient management. Meanwhile, smart control system is conducive to energy saving, consumption reduction, output increasing and emissions reduction, making it possible to improve product stability and quality, maintain production consistency and reduce the intensity of operator.
