Abstract：The air dense medium fluidized bed(ADMFB)dry coal preparation technology has the advantages of less water consumption,less pollution and lower cost,so it is suitable for coal preparation applications in arid areas in northwest China.However,control strategy of ADMFB separation circuits is developing slowly due to the lack of appropriate model.To solve this problem,a coal preparation ADMFB circuit platform was developed in this paper.Firstly,by analyzing the mechanism of each key equipment of the ADMFB circuit.the corresponding part of circuit dynamic mathematical models are developed.Then for simulate the operation performance of the whole ADMFB circuit,a complete model of ADMFB separation circuits was developed based on MATLAB/Simulink,in which the model parameters were identified.Finally,the effectiveness of the circuit is verified by the simulation experiment,and the research results can provide theoretical basis for the research of advanced control methods and optimization strategies in ADMFB dry coal preparation.
