HZG Rotary Dryer

The HZG rotary drum dryer features a slightly inclined cylindrical main body with adjustable rotation speed within a certain range. Wet material is fed into one end of the dryer, where uniformly distributed lifting flights inside the cylinder continuously lift and disperse the material. This ensures even distribution and full contact with co-current (or counter-current) hot air, significantly enhancing heat transfer efficiency and drying dynamics. During the process, the combined action of the inclined lifting flights and hot air flow enables controlled material movement toward the discharge end, where the dried product is discharged through a star valve.
