A STUDY OF PARTICLE MOTION IN ROTARY DRYER

Rotary dryers are a class of dryer commonly used in industry to dry particulate solids (Keey, 1972) They are made of a long cylindrical shell that is rotated The shell is usually slightly inclined to the horizontal to induce solids flow from one end of the dryer to the other In direct heat rotary dryers, a hot...
