THE COMPUTER SIMULATION OF PARTICLES SEPARATION PROCESS ON SHAKING TABLE

Abstract

ABSTRACT An attempt has been made to develop a computer model of shaking table to describing particles separation. The model is based on the way that the particle separation process of shaking table can be divided Into two sub-processes, namely, the vertical stratification and the separation of stratified particles, the former can be regarded as a homogeneous Markov process, the latter can, however, be considered as the cross transfer process with three equal-probabilities in the longitudinal direction of the table. The transfer probabilities of Markov process can be determined via the mathematical analysis based on the fluid mechanics and vibration principles. The cross transfer probabilities depend mainly on the wash water and inclination of shaking table. All of the transfer probabilities of the two sub-processes can develop a computer model which can simulate the particles separation process. Once input the feed and operating parameters to the computer model, prediction can be made on the separation r...
