Rotary Drum Dryer SB-4

Rotary Drum Dryer SB-4 is an industrial device designed for effective drying of sawdust and other materials of plant origin and biomass before further processing. Thanks to the rotating drum and the controlled flow of hot air, the material is dried evenly, which makes it possible to obtain the appropriate moisture content for the production of pellets, briquettes, and other products.

Model SB-4 was designed for companies involved in wood processing, biofuel production, and biomass utilization. Properly selected operating parameters ensure a stable drying process while maintaining high quality of the final raw material.

The material is fed into the drum by means of a screw feeder, where during continuous rotation it is evenly mixed. Hot air flowing through the chamber effectively evaporates moisture, and the dried material leaves the device and is ready for further use.

Key advantages

• Uniform material drying thanks to the continuous rotation of the drum
• High process efficiency allowing the moisture content of the raw material to be reduced quickly
• Operation with various types of biomass, including sawdust and materials of plant origin
• Adjustable drum inclination angle enabling optimization of the drying process
• Effective thermal insulation reducing heat loss
• Solid industrial construction adapted for continuous operation
• Low operating costs thanks to efficient use of thermal energy
• Possibility of integration with pellet and briquette production lines

Application

Rotary Drum Dryer SB-4 is used wherever it is required to reduce the moisture content of biomass before further processing.

• wood pellet production
• briquette production
• wood processing plants
• production of wood-based panels
• biomass processing
• compost production
• production of feed additives

Properly dried material improves the efficiency of subsequent production stages, increases the calorific value of biomass, and affects the quality of the finished product.

How does a rotary drum dryer work?

1. The raw material enters the drum by means of a screw feeder.
2. The rotating drum evenly mixes the material.
3. Hot air flows through the chamber, removing moisture.
4. The control system makes it possible to control the parameters of the drying process.
5. The dried material is discharged for further transport or production.
