Double-drum Dryer

Double-drum dryer is mainly used for drying granular materials with certain humidity and particle sizes, which is a direct type of rotary dryer. The moisture content of dried materials is up to 1-0.5% according to different drying requirements. The difference between the double drum rotary dryer and three-cylinder dryer is the change of the lifting plate. In general, the gas temperature in the drying machine for heat exchange cannot reach 750 ℃. If hightemperature is needed, its cylinder and the lifting plate should be made ofheat resisting steel.

Materials can Be Dried by Double Drum Dryer

Double drum dryer and other drying equipment are almost the same, which are aimed at drying materials. However, the double drum drying machine also has its own unique features. The double drum dryer is mainly used for drying granular materials which are resistant to chemicals, high temperature and dust, such as sand in dry mortar industry, various specifications of molding sand in foundry industry, chemical industry, the blast furnace slag in cement and building materials industries. According to different drying requirements of dried materials, the moisture content of finished products can reach 1-0.5%. The particle size of the materials in the dual-drum dryer should be less than 30mm.

Main Features of Dual-drum Dryer

1. The energy saving efficiency of double-drumdryer is twice as high as the monocular drying machine, so there is greatimprovement in its drying ability.

2. Dual-drum dryer has reasonable structureand convenient operation.

3. The length of double drum rotary dryer hasbeen shortened to achieve convenient installation, which is fully approved byusers.

4. Double drum dryer has wider applicationsthan monocular dryer. It adopts flow drying process, which can be adapted todry clay, coal, slag, iron and other raw materials as well as bulk materials inmetallurgy industry, chemical industry and other departments.

5. It has compact structure, which has supportingwheel to drive the small and big gears, and which leads to convenientinstallation, simple operation and reliable performance.

6. The design of lifting plate is morereasonable, which contributes to better drying of the materials.

7. The double drum dryer is convenient tooperate, which mainly adopts frequency conversion speed regulation to adjustthe speed of the drum. The proper speed will be adjusted according to the waterand production requirements to meet the demand of next procedure.

8. The measurement of temperature adoptsremote monitoring to make it more intelligent.
