Why the rotary drum persists
Material cascades through the hot gas stream thousands of times per pass. There are no screens to blind, no nozzles to clog, and the drum shrugs off lumps that would destroy a flash dryer. For mining, aggregates and biomass, simplicity is the feature.
Typical range we build
| Drum size | Indicative evaporation | Typical duty |
|---|---|---|
| Ø0.8×8 m | 0.3–0.8 t/h water | Pilot plants, small biomass |
| Ø1.2×10 m | 0.8–2 t/h water | Sand, sawdust, small mining |
| Ø1.8×14 m | 2–4.5 t/h water | Ore concentrate, slag |
| Ø2.4×18 m | 4.5–8 t/h water | Large mineral and aggregate |
| Ø3.0×20 m | 8–12 t/h water | High-capacity industrial |
Evaporation depends on inlet moisture, particle size and gas temperature — these are planning figures.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Heat source | Coal, gas, diesel or biomass furnace — and which is cheapest at your site? |
| Flight design | Flight pattern for your particle size; sticky feed needs special arrangement. |
| Dust | Cyclone only, or cyclone + baghouse/wet scrubber for your emission limit? |
| Drive | Girth gear and pinion brand; thrust roller arrangement? |
