Kinematics analysis of grains in a rotary drum dryer

摘要

On the basis of theoretical analysis of the forces applied to grains and moving locus of grains in a rotary drum dryer, residence time and contact heating time of grains in the dryer were calculated. The values of calculation conformed to the measured values. These results provided reliable foundation in theory and practice for further studying and improving the dryer. They also serve as references to other designers of similar type of dryer.
