Double-drum dryer is a direct type rotary dryer machine which is mainly composed of internal cylinder, external cylinder, carrier roller, tyre supporting device, transmission device, feeding and air intake and discharging and air outlet sealing device.

Double-drum dryer is mainly used for drying granulous materials with a certain humidity and granularity such as yellow sand used in dry-mixed mortar industry, various casting sand used in casting industry, blast furnace slag and small-sized clay used in building material and cement industry as well as small-sized materials that do not have chemical changes and that fear no high temperature or smoke used in chemistry. According to the requirement for the final water content of the dried materials in different industries, the water content of the dried materials can reach below 1-0.5%. The size of the materials to be dried by double drum dryer is better small than 30mm.

Working principle:

Similar with other drying equipment, double-drum dryer aims to dry materials. In addition, double-drum dryer has its unique features. At present, double-drum dryer is mainly used to dry particle materials with a certain humidity and granularity, such as yellow sand used for powder mortar industry, various specification sand for casting industry, blast furnace slag for building material and cement industry, and granular clay for chemical industry and other small particles resisting high temperature and dust pollution. According to the requirement to the final moisture of dried materials in different industries, the moisture of dried materials is under 1-0.5%, and the materials in the double-drum dryer is under 30 mm.

Superior Performance of Double Drum Dryer:

1. Double drum dryer has high thermal efficiency and outstanding energy-saving effect. The test has shown that the thermal efficiency of Fote double drum dryer has been much higher than 50% that of traditional single-drum dryer and the coal saving effect is outstanding.

2. Fote double drum dryer has scientific and reasonable structure, high efficiency and energy conservancy. Materials carry out heat exchange with the hot airflow in the internal cylinder in such means as radiation, convection and conduction and in external cylinder in such means as conduction and convection.

3. The length of the dryer machine is shortened, which is conducive to technical arrangement.

4. This drying machine adopts the technology that materials are dried in the cocurrent flow of the hot airflow, so that the application range is wide. It is suitable for drying various raw materials such as clay, coal, slag and iron powder as well as various bulk materials in metallurgy, chemistry and other industrial departments.

5. The structure of this dryer machine is compact.

6. The external superficial area of this machine is reduced by over 30% than that of single-drum rotary dryer, and the outer cylinder has heat insulation function to the inner cylinder, so that the surface temperature of the outer cylinder is low and the heat loss is low, thus greatly improving the working environment and conditions while ensuring high efficiency and energy conservancy.
