HZG Series Revolving Cylinder Dryer
When the damp raw material is fed from one terminal, it is turned over through blades that are distributed inside the cylinder and will be distributed uniformly in the drier and contact fully with the countercurrent hot air. In this way, the process of heat conduction is increased.
Detailed description
Features：
● High in the etent of mechanization and strong in production capacity.
● The resistance for fluid passing through the cylinder is small. The consumption of power and energy is low.
● It has strong adaptability to the properties of raw material. The operation is stable. The cost of operation is cheap
● The uniformity of dried substance is good.
Description：
When the damp raw material is fed from one terminal, it is turned over through blades that are distributed inside the cylinder and will be distributed uniformly in the drier and contact fully with the countercurrent hot air. In this way, the process of heat conduction is increased. During the period of dry, under the effect of incine blades and hot air stream, raw material can be moved to the star section of drier and discharged from disharged form discharging valve.
Practical：
Applicable for drying big particles, heavy particles in chemical, mining, and metallurgy, such as mining area, cinder of blast furnace, coal, powder of metal, phosphate fertilizer and thiamine. For drying the powder or particles with special requirements, such as HP foaming blowing agent, residule of alcohol, light calcium carbonate, active clay, magnetic powder, graphite, and residue of medicine. For materials to be dried under low temperature and large lot continuous production .
