SAWDUST DRYER FOR CHARCOAL BRIQUETTE PRODUCTION
Why Plant Expansion Often Exposes the Drying Bottleneck
When a charcoal briquette plant expands, the sawdust dryer can become the line bottleneck. Dryr provides four rotary drum dryer sizes from 0.8–2 t/h and can be customized with a 17–18 m drum for longer material residence time, helping match water evaporation to the briquetting line instead of starving downstream equipment.
Select the Rotary Sawdust Dryer by Water Evaporation
Dryr is an industrial sawdust dryer and continuous sawdust drying machine for the pre-treatment stage before charcoal briquette production. Its four reference models cover the requested range: H-1010 with a 1000 mm drum and 0.8–1 t/h, H-1212 with a 1200 mm drum and 1–1.2 t/h, H-1512 with a 1500 mm drum and 1.2–1.5 t/h, and H-1815 with an 1800 mm drum and 1.5–2 t/h. The correct selection should start with initial moisture, particle size, target moisture, heat source, operating hours, and required dry-feed rate. This water-evaporation calculation leaves practical buffer for the briquetting line instead of sizing the rotary sawdust dryer only to the press nameplate. The documented target is outlet moisture below 10 percent, subject to project conditions and confirmation.
Use Drum Length and Internal Flights to Add Drying Duty
A sawdust rotary drum dryer uses hot air from a furnace while the rotating drum lifts, disperses, and advances the material. The Dryr gallery shows the working details: internal lifting flights and bolted mounting points in the drying chamber, a girth gear with pinion, gearbox, and motor for drum rotation, and a system layout with process ducting, blower, cyclone separator, and control cabinet. These images are evidence of structure and process layout, not a substitute for a site-specific performance test. For a project that needs more drying duty, the drum can be discussed and customized up to 17–18 m to extend residence time and improve evaporation capacity. Such a long drum may require split shipment, on-site assembly, installation, and commissioning, so the plant should confirm lifting access, foundation space, duct routing, and service scope before ordering.
The Result: Feed the Charcoal Briquette Line at Its Planned Rate
With the dryer matched to the water load and the downstream dry-feed requirement, a charcoal briquette plant can keep the briquetting machine supplied instead of allowing front-end moisture control to throttle the line. Continuous sawdust drying reduces dependence on sun drying and manual handling; when PLC control, conveyors, and the selected dust-control system are included in the project, it can also support more consistent operation and dust management. A below-10-percent outlet moisture target may help stabilize the feed condition, but the final result depends on the raw material and process settings. For sizing, send the initial and target moisture, particle size, required charcoal briquette output, fuel preference, operating schedule, available space, and dust-control requirements. The Dryr team can then review the 0.8–2 t/h model range and the possible 17–18 m rotary drum configuration.

- The 0.8–2 t/h capacity range is presented as a reference for the four models and is qualified by raw-material moisture, particle size, heat source, target moisture, and required output.
- The 17–18 m drum length is described as a project customization for longer residence time and water evaporation, with split shipment and field assembly discussed as planning items.
