However, the effect of each is difficult to quantify in practice as these two parameters are usually interrelated Based on experience acquired over the years and the investigative work conducted by FC Bond, it was established that the optimum circulating load for a closed ball mill – cyclone The higher the column height, the finer the separation particle size However, if the height of the column exceeds a certain limit, it will lose its effect due to the increase in the feed pressure loss 6 Hydrocyclone Cone Angle The cone angle has an important influence on the classification efficiency of the hydrocyclone6 Factors Affecting Hydrocyclone Efficiency The effect of dust concentration on the performance of the dust collector is due to the increase of the friction loss between the dust particles, the decrease of the rotational speed of the air flow, and the decrease of the centrifugal force, so that the resistance and efficiency are reducedFactors that affect the performance of cyclone dust
