Introduction of equipment

Rotary steam tube dryer (RSTD) is a kind of indirect-heated rotary dryer. The difference against the normal rotary dryer is that the former has steam tubes installed in the cylinder. The tubes are arranged in concentric rows, extend the full length of the shell and supply the heat for drying. This dryer is heat-conduct type equipment. There are atmospheric type and gas -tight type. The later is suitable for combustible and explosive situation. According to drying process requirement, there are counter-current type and co-current type. By the character of product, either powered or unpowered discharge screw can be chose for material feed and discharge.

The dryer is mainly comprised of shell, steam chest, heat exchange tubes, support rollers, driving unit, feed/discharge side seal, feed/discharge framework, etc.

characteristics

• High heat transfer coefficient and high thermal efficiency
• Large treatment capability, wide application
• Well drying effect
• Indirect-heating, no material contamination
• Retention time can be adjusted, low energy consumption
• Convenient operation and easy maintenance
• Gas-tight type for explosive-proof situation

Specifications and models

Now we can produce a variety of specifications of the RSTD. According to diameter, there are 800mm-4800mm series, length from 3m to 39m. Construction material can be carbon steel, 304L, 316L and duplex. Customized design is also available.
