coke drying in the steel industry - feeco international inc

In addition to choosing appropriate temperatures and retention times, rotary dryers for coke are designed with a co-current airflow, meaning that the material and process gas flow in the same direction. A co-current airflow puts the wettest material in contact with the …

co-current drying in high-revolution rotary dryer

co-current drying in high-revolution rotary dryer

Jan 31, 2014 · The high-revolution rotary dryer was developed for the biomass thermal treatment. The apparatus operates on the mechanical fluidization principles, which are achieved by the effect of centrifugal and gravitational forces. Centrifugal forces are growing by increasing the revolutions. With their influence, the fluidized material is uprising and by influence of gravitation forces is passing down
