Are you facing these common drum drying problems?
- Sludge, sand, or slag has high moisture content, and your old drum dryer can't fully dry them?
- Need to dry over 100 tons of material daily, but your drum dry process is too slow?
- Spending too much on electricity because of your old drum dryer?
These are exactly the issues our clients used to face. Our single drum dryer solutions have helped over 100 factories lower energy costs and improve performance.
Let's see how this system can solve your drying problems!
One reliable solution: The single drum dryer
1. High capacity drum drying – lower cost per ton
The single-drum dryer can process 1.9–76.0 tons of materials per hour. For industries that require large-scale drying, it means fewer equipment, lower installation costs, and higher production efficiency.
Suitable for large-volume materials:
- Sand (Yellow sand, sea sand, river sand, quartz sand, glass sand, etc.)
- Coal, coal slime/slurry
- Fly ash, tailings
- Various ores (gold, nickel, iron, copper, gypsum, manganese, phosphate, etc.)
2. Moisture flexibility – up to 85% humidity
Through the strengthening of the lifting plate and the efficient heat exchange system, the thermal efficiency is greatly improved.
The single-drum dryer can heat dry materials with a maximum moisture content of 60–85% to 1–10%, completing precise drying.
Applicable to high-moisture materials:
- Urban sludge, industrial sludge
- Clay, gypsum
- Slag, steel slag
If you are a sludge treatment plant or a building materials mixing station, the moisture content of the materials fluctuates greatly and the traditional drying equipment is unstable, then the single-drum dryer is particularly suitable for you because it can handle a maximum humidity of 85% and has stronger adaptability.
3. Save 15–30% energy – smarter than conventional drum dry systems
Compared with traditional rotary dryers or fluidized bed dryers, single-drum dryers have higher thermal efficiency, less exhaust heat loss, and energy saving of 15–30%.
Particularly important for the following scenarios:
- Mineral processing plants
- Biomass pellet production
- Coal drying plants
- High energy consumption sensitive industries
If you are running a mineral drying plant, a single drum dryer can help you save at least 20% of your fuel consumption per month, which means a significant cost reduction.
4. Easy maintenance – built for heavy duty
One drum, one heat source system — takes up less space and is easier to install.
With fewer moving parts and wear-resistant materials, it offers a longer service life. Ideal for heavy-duty, high-frequency operations and easy to maintain even in remote locations.
Application industries include mining, building materials, coal, chemicals, steel, environmental protection, etc.
Three factors for correctly choosing a single drum dryer
To choose a suitable single-drum dryer, you actually only need to understand the material's inlet and outlet moisture, hourly drying output, and available fuel types.
1. Inlet and outlet moisture content of the material
The moisture content of the material determines the required heat source, drum dryer size, and residence time during drum drying.
Typical applications based on moisture levels:
- Sludge: Inlet moisture 55–85%, outlet ≤10%
- Sand and gravel: Inlet 8–12%, outlet ≤1%
- Biomass: Inlet 30–45%, outlet 10–15%

2. Drying capacity
The more the drying output, the larger the dryer drum diameter and the longer the drum.
We offer different models from small drum dryers to large drum dryers. The following are our hot selling models: Request a Quote
| Model | Capacity (t/h) | Shell Cubage (m?) |
| Φ1.5×14 | 5.3–6.6 | 24.7 |
| Φ2.2×12 | 9.7–12.2 | 45.6 |
| Φ3.0×20 | 30.1–37.7 | 141.3 |
| Φ3.6×28 | 60.8–76.0 | 285 |
3. Fuel type
The available fuel types determine the heat source and combustion system. We offer a variety of fuel options based on your location and cost preferences.
Supported fuels:
- Solid fuels: coal, biomass pellets, rice husks, wood
- Gas fuels: natural gas, biogas, coal gas, liquefied petroleum gas, waste heat flue gas, steam
- Liquid fuels: diesel, heavy oil, biomass oil.
Single drum dryer in a Brazilian coal slurry drying plant
A coal processing facility in Brazil needed to dry coal slurry with high initial moisture content for easier transportation and more efficient combustion.
Located in a humid, tropical climate, the plant required a drum dryer that could handle sticky, high-moisture materials and operate continuously with minimal maintenance.
We recommended using a single-drum dryer. Its core working principle involves lifting plates inside the rotating drum that repeatedly lift and cascade the material through hot air, ensuring full exposure and accelerating moisture removal.
Drying solution:
- Material: Coal slurry
- Inlet moisture: 45–55%
- Final moisture: ≤15%
- Drum dryer model: Φ3.0×20
- Heat source: Coal-fired hot air furnace
- Daily capacity: 300 tons
Customer feedback:
"Thanks to the single drum dryer's strong drying capacity and anti-stick design, the coal slurry was processed efficiently, with stable performance and lower fuel usage."
