Abstract: The three-dimensional design method promotes the efficiency of coal preparation plant design effectively. But so far, there is no set of equipment model and information management system to meet the needs of design processing and multipurpose utilization requirements, which reduces the efficiency of CPP design severely. This paper illustrates the basic framework and construction process of the equipment model and information management system which is developed by Beijing Huayu Engineering Corporation Limited, and it also introduces the application process of the system.
