HZG High Efficiency Continuous Rotary Drum Dryer for Plastic
Sheet/Plastic Laminate
WORKING PRINCIPLE
Rotary Drum Drier is a kind of dryer with rotating cylinder body
which is a little bit incline. The wet material is loaded from
one end from the screw material adding device continuously, and is
stirred by the bafflers that are uniformly distributed in the
barrel.The material is uniformly distributed and dispersed in the
dryer and fully contacts the hot air of counter flow. When the
material passing through the cylinder inside surface, it will
contact with the hot air circling inside and being dried .Most of
the dried product will be discharged from the other end of the
dryer. Small part of the fine granule goes into the cyclone
separator with the exhaust air. The powder will be separated and
collected, and the exhausted air will be ejected to the atmosphere.
During the drying course, the material will slowly move to the
lower end from the higher part recur to the slowness rotating of
the cylinder

APPLICATION
This dryer widely used in the following industries:
- Drying large particles and heavy material for chemical, mining,
metallurgy and other industries, such as: mining, blast furnace
slag, coal, metal powder, fertilizer, ammonium sulfate.
- Drying powder or granular materials which have special
requirements, such as: HP vesicant, lees residue, precipitated
calcium
carbonate, activated clay, magnetic powder, graphite, dregs.
- Drying the material which required low-temperature and continuous
drying process.
