HG Rotary Drum Dryer

Description
After the wet materials are fed into the rotary drum dryer, they are stirred by the shoveling plates and uniformly distributed in the cylinder. Then the materials fully contact with cocurrent of counter-current hot air, thus accelerating heat transfer and mass transfer. During the drying process, the materials under the effect of titled shoveling plates and hot air can move to the discharge valve at the other side of the cylinder dryer and finally be discharged.

Application
1.HG rotary drum dryer is designed to dry large particles, such as ore, blast furnace slag, coal, metal powder, phosphate fertilizer and ammonium sulfate in the chemical, mining, metallurgical and other industries.
2.This drying equipment can be used for drying special powdery and granular materials, including HP foaming agent, vinasse slag, light calcium carbonate, activated clay, magnetic powder, graphite and dregs.
3.HG cylinder dryer can dry the materials that require low temperature and continuous drying.

Features
1.HG rotary drum dryer possesses high level of mechanization and large production capacity.
2.This drying equipment has strong applicability to the material properties.
3.This drying machine can designed with multilayer inner sleeve structure. So the staying time of the material can be longer and the production capacity can be greatly enhanced.
4.Our rotary cylinder dryer has the advantages of stable operation, low operating cost and good drying uniformity.
