Rotary dryers contain lifters to lift the material away from the bottom of the dryer and then to drop it through the gas to promote mass and heat transfer between the granular material and the
Abstract. Lifter use in dryers improves mass transfer by increasing the amount of surface area available for transfer and also by increasing the velocity of gas over the particle surface. An even
Lifter B, which is the similar to Lifter A but is inclined at angle has a higher hold up, a larger range but a smaller flux. This reflects that the apex of Lifter B is closer to the dryer wall during rotation so the amount of material lost during a small angle of
