Abstract: In order to quickly determine the most suitable equipment model and parameters in indus⁃ trial production and reduce the energy consumption in the grinding process，in view of the complex charac⁃ teristics of multi-parameter，slow time-varying，nonlinear and large lag in mineral crushing and grinding， and the large fluctuation and difficult control in the grinding and classification process，it is easy to cause poor product quality，large resource consumption and high energy consumption. The simulation model of SABC beneficiation and grinding process is built. The model establishes four crushing and grinding process⁃ es to improve the model's adaptability to the scene range and operational flexibility，and develops an EX⁃ CEL interface for data exchange. While the model automatically simulates the entire crushing and grinding process to obtain the optimal equipment model and parameters，it can intuitively and quickly help field op⁃ erators adjust equipment parameters.

Key words: METSIM, crushing and grinding, data exchange
