Three Drum Dryer

Three Drum Dryer is also called three-cylinder dryer or triple-drum dryer, enjoys the today's Germany advanced technology. Three-drum drying machine is combined of three concentric cylinders with different diameters in certain mathematical relationships and structure, so it's applicable to energy saving drying of all kinds of powder, granular, strip, and bulk materials, such as sand, quartz sand, clay, copper shavings, iron scraps, aluminum shavings, wood chips, leaves, mineral powder, mineral grain size, magnetic powder, carbon granules, tea residue, granulation fertilizer, chicken manure and so on.

Three-drum dryer or three-cylinder dyer mainly used to dry granular materials with certain humidity and particle size, such as yellow sand, foundry sand, slag, coal cinder, clay with small particle size and other granular materials that resist to high temperature, dust and smoke. Moisture content of materials after drying can reach 1 to 0.5 % or below. It is one of the wet materials drying equipment, which is highly efficient and energy-saving product improved on the basis of single-cylinder rotary dryer.Three-drum dryer or double-drum dryer has compact structure and covers a small area which is half of the single drum dryer does.

The three-drum dryer is used to dry particle materials with certain humidity like yellow sand used in the dry powder and mortar industry, and many kinds of sands used in the casting industry.

Main feature of Three-cylinder Dryer Machine

Three-drum dryer has compact structure and covers a small area which is half of the single drum dryer does. The three-drum dryer works reliably with low energy consumption and high heat efficiency which realizes good material drying effect, simple automation control and few operating staff.

Principle Of Three Drum Dryer

Materials enter the inner side of the drum through the feeding device to realize current flow drying process, then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process. They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way. The three-drum dryers absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.
