Dr. Tongbo SUI is currently a vice president of Sinoma International, CNBM. He has been intensively engaged for over 20 years in R&D of low energy & low CO2 clinker cements. Before joining Sinoma in 2010, he worked as vice president of China Building Materials Academy during 2006-2010. He is now also visiting professor at the University College London of the UK and a senior advisor of the China Cement Association, and active in international organizations as co-chair of WKG5 for Cement Innovation under GCCA, and a Fellow of ICT.
The Digitization Work of Smart Cement Plant in China
This article is to introduce the digitization work of smart cement plant/group in China. To save power and promote the product quality, delicacy management in variety ways of digital transformation is the best tool for the new built, or existing cement plants. New technologies, such as special integrated robots, online equipment, information plant form, cement process digital applicant (SAAS), AI and APC control, are implemented to approve the traditional ways of operation. A variety of AI algorithms are used in the construction of intelligent factory. Based on the neural network algorithm, a number of functions, including closed-loop control of raw meal quality, prediction of free calcium, prediction of clinker strength and so on, are realized, so that the cement production process can achieve self-learning and global optimization effects, with strong adaptability and robustness. Combined with quality prediction, furnace state recognition and quantitative recognition of fire TV video images, the furnace system is feedforward controlled, which solves the control problems of prolonged combustion system, large inertia and strong coupling. The system gives the global optimal recommended value of the control objective through calculation, and the system can operate continuously and stably under steady state conditions. By 2~5% power saving and 20% staff simplification, engineers in China and plant management are still working together to figure out the way of new management mode, on the digital basis. Meanwhile, the cement groups are also developing the production information plat form, by merging the ERP data, sales business to lower down the total cost. This paper tries to introduce the digital efforts that are carried out in the smart cement plants and shows the methodology of implementation.
