Henan Hongke Heavy Machinery Co., Ltd. is proud to announce the successful trial run of a Φ 2.2×45m catalyst rotary kiln production line at our customer's facility in Kaifeng, Henan, China. This is a brand-new system—engineered from the ground up for high-precision catalyst calcination.
Why This Customer Chose Us
Our customer in Kaifeng is a well-known chemical manufacturer specializing in catalyst production. They needed more than just a machine—they needed a reliable partner who could deliver consistent product quality, minimize operating costs, and provide long-term peace of mind.
After evaluating several suppliers, they chose us. Here's why:
Complete, brand-new system – no refurbished or second-hand equipment
Indirect heating design – keeps the catalyst pure by preventing any contact with combustion gases
Multi-zone temperature control – ensures uniform product properties with ±5°C accuracy
Inert gas capability – protects sensitive catalyst materials during processing
24/7 reliability – built for continuous operation with minimal downtime
We listened to their needs. Then we delivered a system that meets every requirement.
What We Supplied
A complete, custom-engineered calcination line built around a Φ 2.2×45m indirect-fired rotary kiln.
| Key Feature | Specification |
|---|---|
| Kiln size | 2.2 m diameter × 45 m length |
| Heating type | Indirect (external) – no flame or flue gas touches the product |
| Temperature range | Up to 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 heating furnace (gas or electric)
Inert gas sealing system
Product cooling section
Multi-stage dust collection
PLC-based automation with full data logging
Why Indirect Heating Is the Right Choice
Catalysts are sensitive materials. Any contamination can ruin their performance. That's why we used an indirect-fired design – the kiln shell is heated from the outside by an external furnace shroud, so the catalyst never touches the flame or flue gases.
This design ensures:
Product purity – no contamination from combustion byproducts
Precise control – different temperature zones for different process stages
Atmosphere flexibility – can run with air, nitrogen, or reducing gases
Trial Run Results – Proven Performance
The trial run was a complete success. The system performed exactly as designed:
| Test Parameter | Result |
|---|---|
| Temperature stability | All zones held setpoint within ±5°C |
| Atmosphere integrity | Inert gas maintained throughout operation |
| Product quality | First batches met all customer specifications |
| Operation reliability | Ran smoothly with minimal supervision |
What This Means for Our Customer
| Benefit | Value |
|---|---|
| Consistent catalyst quality | Fewer rejects, better customer satisfaction |
| Product purity | Indirect heating prevents contamination |
| Lower operating costs | Efficient heating, minimal waste |
| Full traceability | Data logs for quality certification |
| Reliable after-sales support | One partner from design to ongoing service |
