Cement Plant 3D simulation project as a whole, by shape simulation, operation simulation, visual experience simulation, using real cement plant model and virtual reality technology, makes the users feel personally on the plant with a wonderful experience. The uncertainty to a specific process can be translated into the influence on the entire process and performance of the whole plant by Data Model. Cement plant simulation model by computer theoretical model and the risk estimation on certain specific process can predict the outcome of future generated. With this technology, users can plot the construction scheme; estimate the investment and the production rate & energy consumption as a reliable reference for the modification of the process and selection of the equipment. System with 3D simulation and big data analysis techniques, by observing the model data to create three-dimensional model, paste texture, generate three-dimensional model database, generate a visual model and other steps, and extend the benchmarking data. The bottleneck problem encountered in the course of production will be analyzed by data collecting and statistics and solved by focus monitoring and technical modification measures. The modification and upgrading proposal can vividly and visually display the effect the modification and ensure the premium quality by the Data Simulation Technology.
