HZG Rotary Drum Dryer
The HZG rotary drum dryer is a cylinder whose main body is slightly inclined and can adjust the rotating speed within a certain range. The wet materials are fed into the cylinder by the feeder. The materials are evenly distributed and dispersed in the dryer and fully contact with the hot air (parallel flow or countercurrent) passing through the cylinder when the plate reader uniformly distributed in the inner cylinder turns.

Working principle
  After the wet material is put into the dryer from one end, the material is evenly distributed and dispersed in the dryer under the overturning of the plate reader uniformly distributed in the inner cylinder, and fully contacts with the co-flow (countercurrent) hot air, which accelerates the drying heat transfer and transfers to the driving force. During the drying process, the material can move to another section of the star discharge valve of the dryer to discharge the finished product under the action of the inclined plate reading and the hot air flow.
Performance characteristics
◎ The rotary dryer has high mechanization and large production capacity.a.jpg
◎ The resistance of fluid passing through the cylinder is small, and the function consumption is low.
◎ Strong adaptability to material characteristics.
◎ Stable operation, low operation cost and good uniformity of product drying.
Applicable materials

◎ Large particles and materials with large proportion in chemical, mining, metallurgy and other industries are dry, such as mines, blast furnace slag, coal, metal powder, phosphate fertilizer and ammonium sulfate.

◎ Drying of powder and granular materials with special requirements, such as HP foaming agent, distiller's grains residue, light calcium carbonate, activated clay, magnetic powder, graphite, and drug residue.

◎ Materials requiring low temperature drying and mass continuous drying.
