Henan Hongke Heavy Machinery Co., Ltd. is proud to announce the successful trial run of a Φ2.5×55m catalyst rotary kiln production line at our customer's site in Hubei, China. This is a brand-new system—built from the ground up for high-precision catalyst calcination.
Why This Customer Chose Us
Our customer in Hubei is a well-established chemical producer specializing in industrial catalysts. They were looking for a reliable partner who could deliver a complete, modern calcination system—not just a machine, but a solution that would give them consistent product quality, low operating costs, and long-term peace of mind.
They had clear requirements:
Uniform product quality – every batch must meet the same high standard
Precise temperature control – critical for catalyst performance
Inert gas capability – for sensitive catalyst grades
24/7 reliability – no unexpected downtime
Brand-new equipment – no refurbished or second-hand units
We listened. Then we delivered.
What We Supplied
A complete, custom-engineered calcination line built around a Φ2.5×55m indirect-fired rotary kiln.
| Key Feature | Specification |
|---|---|
| Kiln size | 2.5 m diameter × 55 m length |
| Heating type | Indirect (external) – no combustion gases touch the product |
| Temperature range | 400–1,000°C (zoned control) |
| Temperature accuracy | ±5°C |
| Atmosphere | Air, nitrogen, or reducing gas – fully controllable |
The system includes:
Precision screw feeder for consistent material feed
Multi-zone electric/gas-fired heating furnace
Inert gas sealing system
Product cooling section
Multi-stage dust collection
PLC-based automation with full data logging
Why Indirect Heating Matters
Catalysts are sensitive. Any contamination from combustion gases can ruin their performance. That's why we used an indirect-fired design—the kiln shell is heated from the outside, so the catalyst never comes into contact with flame or flue gas. This ensures product purity and allows precise control of the processing atmosphere.
How We Ensure Quality
| Feature | What It Delivers |
|---|---|
| Zoned temperature control | Different temperatures along the kiln length – exactly as the process requires |
| ±5°C accuracy | Consistent product properties, batch after batch |
| Inert gas seals | Protects oxygen-sensitive catalyst materials |
| Variable speed drive | Adjust residence time to fine-tune product characteristics |
| Automated monitoring | Less manual work, fewer errors |
Trial Run Results – Confirmed
The trial run proved the system performs exactly as designed:
Temperature stable – all zones hold setpoint within ±5°C
Atmosphere secure – inert gas maintained throughout
Product quality confirmed – first batches met all customer specifications
Ready for 24/7 operation – system runs smoothly with minimal supervision
What This Means for Our Customer
| Benefit | Value |
|---|---|
| Consistent catalyst quality | Fewer rejects, better customer satisfaction |
| Lower operating costs | Efficient heating, minimal waste |
| Full traceability | Data logs for quality certification |
| Long equipment life | Built with heavy-duty materials and proper engineering |
| Peace of mind | One reliable supplier – from design to after-sales support |
