Coal steam drying drum dryer belongs to indirect heating mode, the heat conduction oil or steam drying heat, this type of dryer has low energy consumption of drying, the safety drying process, the material is not affected by heat source pollution etc.,which are widely used in the biomass, food, feed, fertilizer, bad slag chemical industry, medicine, coal, mining and other small particles or weakly caking dry powder material.

Heat conduction oil steam drum dryer, mainly composed of tube type heat exchanger, heat sources in and out center pipe, rotary drum, feeding and discharger of the machine, induced draft fan, dust collector and distribution cabinets.Wet material enters into the dryer, uniformly distributed in the roller feed plate and the column tube turning, with a full contact with hot  conduction oil (steam)  tube type heat exchanger, realizing heat transfer, mass transfer (110-250 ℃), constant temperature drying, water vaporization and scattered with the air emissions, gradually reduce the moisture from the material, the material has finished the drying process.
