INVESTIGATION ON CLASSIFICATION EFFICIENCY FOR

2020-7-8 · The effect of the settings of the classifier vane angle on the coal classification efficiency was numerically investigated by several researchers [2, 20-22]. The effect of inlet air velocity, flow vortex and turbulence on the efficiency of a scaled-down model of a static-air classifier was investigated by using a two-dimensional CFD model. The mixture of gas-coal particle flow inside the crossflow air classifier was simulated based on Euler-Lagrangian approach. Author results showed that the surrounding vane angles could play an important role in enhancing coal classifier efficiency. Shah et al. evaluated the optimum vane angle that provides uniform flow rates and desired coal finesses whereas maximizing the classification efficiency at the outlet pipes. Results showed that at a vane angle opening of 65% was optimal to attain a 60% classification efficiency while the particle size was maintained smaller than 75 µm. Afolabi et al. used a scaled laboratory classifier model to measure the swirl velocity components of the airflow inside the classifier.
