Prediction Separation Performance of Teetered Bed Separation for Coarse Coal Slime

Abstract

Abstract. The paper focuses on separating the coarse slime for the particle size ranging from 0.3 mm to 2 mm in the teetered bed separator. The product yield and ash are researched as well as the partition ratio. The result shows that R-Z model and Das model give prediction with worse precision，Asif model and Galvin model obtain better precision. When the teeter water velocity is quite low, Asif model get better result, and while the velocity is rather high, Galvin model is a better prediction model. The models are validated through the experimental data.
