Henan Hongke Heavy Machinery Co., Ltd. just completed shipment of a custom 1.2×10m rotary dryer with external insulation to a customer in Linyi, Shandong. Here's a quick look at what we delivered and why it matters.
What We Sent
The heart of this order is a Φ1.2m × 10m rotary dryer. It's built for continuous operation and comes with a heavy-duty external insulation layer—a feature that makes a real difference in daily operation.
Key specs at a glance:
| Parameter | Value |
|---|---|
| Dryer diameter | 1.2 meters |
| Dryer length | 10 meters |
| External insulation thickness | 100–120 mm (customized) |
| Shell surface temperature (with insulation) | ≤ 60°C |
| Shell surface temperature (without insulation) | ~150–200°C |
| Heat loss reduction | ~95% compared to uninsulated shell |
| Typical throughput capacity | 1.5–3.5 t/h (material-dependent) |
| Feed moisture range | Up to 70% |
| Output moisture range | As low as 10–15% |
| Rotation speed | 3–5 RPM (adjustable) |
| Power rating | 7.5–11 kW |
Why We Built It This Way
Here’s the thing—many dryers waste a ton of heat through the bare shell. Without insulation, the outside surface can get up to 150–200°C. That's lost energy, plain and simple.
We added 100–120 mm of high-grade insulation on this unit. The result? Surface temperature stays below 60°C, even during peak operation. That means:
Fuel savings —more heat stays inside, doing the actual drying
Faster drying cycles —consistent internal temps mean better moisture removal
Safer handling —cooler exterior means no burn risk for operators
Longer equipment life —insulation also protects the shell from weather and corrosion
Technical Highlights Worth Mentioning
Lifting plate design: Custom internal structure ensures even material distribution and prevents dead zones inside the drum.
Sealing system: High-efficiency labyrinth seals minimize air leakage, keeping thermal efficiency high.
Drive system: Heavy-duty gear and pinion setup with a reliable motor-reducer combo—smooth start and stable torque.
Support rollers: Self-aligning roller assemblies reduce wear and keep the drum running true.
Installation & Commissioning
We supplied the full package: main dryer, drive unit, support structure, feeder, discharger, and ducting. The customer's team handled site installation, and we provided remote technical guidance via video calls and detailed manuals. Commissioning is scheduled within two weeks of arrival.
