INVESTIGATION ON CLASSIFICATION EFFICIENCY FOR

2020-7-8  Fundamentally, the air classifier inside the coal mill filters the fine coal particles through the loss of momentum caused by the collisions between coal particles and the blades of the classifier. This procedure represents the filtering process of the ground coal whereby the coal classifier allows the finer coal particles to pass through to the boiler to be burned while the heavier coal particles are sent back for regrinding. Accordingly, the classifier blades’ design can play an important role in improving the combustion efficiency inside the boiler. Figure 1 shows the selected classifier blade angles for the model of this study which are 70, 60, 50 and 40 degrees. The effect of the classifier blade angles shown in Fig. 1 on the coal classification efficiency is investigated due to its potential to capitalize on the interaction between coal particles and the classifier. A steeper angle of inclination of the blades could increase the potential for collisions between the classifier blades and coal particles leading to a greater quality of classification.
