Three-drum Dryer is also called three-cylinder dryer, whose main body is composed of three concentric circles of different diameters in inlaid combination. It is mainly used for drying granular material with certain humidity and certain particle size range, such as sand, molding sand, slag, cinder, fine-grained clay, high temperature resistant and dusty particles. The moisture content can reach 5 - 15% after the drying process.

Applications of Three-drum Dryer

Three-drum dryer is widely used in building materials industry, metallurgy industry, ore dressing industry, chemical industry, cement and other industries. It is suitable for drying slag, limestone, quartz stone, clay, sand, coal, iron, slag and other admixture; dry mixed mortar, yellow sand and bentonite in construction industry; waste slag, concentrate and tailings in chemical industry; coal slime, raw coal, flotation coal concentrate and mixed coal in coal industry.

Advantages of Three-drum Dryer

Compared with traditional dryer, three-drum dryer has obvious advantages;

1. The discharging temperature is less than 50 degrees, which can directly enter into the base, without cooling.

2. No wind leakage phenomenon, which completely solves the sealing difficulty. It can be installed within 2 hours.

3. The thermal efficiency is as high as 80% (traditional single cylinder drying machine is only 32%), the efficiency has been improved by 48%.

4. The occupied area has reduced about 50%, the investment decreases about 50% than single cylinder dryer.

5. The coal consumption is1/3 of the single cylinder dryer, save 40% energy. The standard coal consumption for per ton is less than 9 kg, the annual coal saving of small drying machine is 50-100 million, and the large dryer is 100-200 million.

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.
