HZG series rotary drum dryer-Changzhou Zhihong Drying Technology Co., Ltd

Description: After the wet material is inserted from one end of the dryer, the material is evenly distributed and dispersed in the dryer under the flipping of the inner evenly distributed plate reader

Category: Drum dryer
Detailed explanation:

Overview:
After the wet material is inserted from one end of the dryer, under the flipping of the uniformly distributed plate reader in the inner cylinder, the material is evenly distributed and dispersed in the dryer, and fully contacts with the co current (counter current) hot air, accelerating the drying flow and mass transfer driving force. During the drying process, the material can be adjusted to move to the star shaped discharge valve at the other end of the dryer to discharge the finished product under the action of the inclined plate and hot air flow.

Application:
● In industries such as chemical, mining, and metallurgy, large particles and materials with high density are dried, such as ore, blast furnace slag, coal, metal powder, phosphate fertilizer, and ammonium sulfate.
● Drying of powdered and granular materials with special requirements, such as HP foaming agent, distiller's grains residue, lightweight calcium carbonate, activated clay, magnetic powder, graphite, and pharmaceutical residue.
● Materials that require low-temperature drying and require continuous drying in large quantities.

Features:
● The rotary dryer has a high degree of mechanization and a large production capacity.
● The fluid has low resistance through the cylinder and low functional consumption.
● Strong adaptability to material characteristics.
● Stable operation, low operating costs, and good uniformity of product drying.
