Henan Hongke Heavy Machinery Co., Ltd. is pleased to announce the successful trial run of a Φ 1×12m electric-heated stainless steel rotary kiln at a customer site in Quzhou, Zhejiang Province, China. This is a brand-new installation—not a refurbishment, not an upgrade of old equipment—engineered for high-purity processing under controlled atmosphere.
Project Background: Precision Thermal Processing in Quzhou
Quzhou, located in western Zhejiang Province, has developed a strong advanced materials and chemical processing sector. The region's industries require specialized thermal equipment capable of handling sensitive materials under strictly controlled conditions.
Our customer in Quzhou operates in the advanced materials sector, processing specialty chemical products that demand high purity and precise temperature control. Their existing equipment could not deliver the consistency or cleanliness they needed. They required a new kiln system that could meet stringent processing requirements.
They came to us with clear needs:
High-purity processing – no contamination from the kiln itself
Electric heating – clean operation, no combustion gases
Controlled atmosphere – inert gas capability for sensitive materials
Precise temperature control – stable results across zones
Reliable operation – continuous production with minimal downtime
Brand-new equipment – no used or refurbished machinery
Complete system – not just a kiln, but the full line
Why This Customer Chose Henan Hongke Machinery
After evaluating several suppliers, the customer selected Henan Hongke Heavy Machinery for several reasons:
1. Stainless Steel Construction for Purity
The customer's material is sensitive to contamination. Carbon steel kilns can introduce rust and metal particles into the product. Our kiln is fabricated from stainless steel (304 or 316L, selected based on the chemical environment). This ensures the product stays clean throughout the process.
2. Electric Heating for Clean Operation
Electric heating eliminates combustion gases, burners, and fuel handling. For the customer's process, this means:
No contamination from fuel combustion
Precise temperature control with fast response
Cleaner working environment
Compact footprint—no burner system or fuel storage
3. Controlled Atmosphere Capability
The kiln is equipped with advanced sealing systems that allow an inert atmosphere (nitrogen, argon, or controlled gas mix) to be maintained throughout the process. This is essential for materials that are sensitive to oxidation.
4. Custom-Engineered for Their Material
We don't sell generic kilns. Our engineering team designed this Φ 1×12m kiln around the customer's specific material characteristics—including particle size, moisture content, and thermal behavior.
5. Complete, Brand-New System
The customer wanted a purpose-built system, not a refurbished unit. We delivered a complete production line, built from the ground up.
6. One-Stop Solution
We supplied the full scope—feed system, kiln, heating system, atmosphere control, discharge, and controls. The customer didn't have to coordinate multiple suppliers.
7. Long-Term Support
The customer wanted a partner who would be there after commissioning. We provide spare parts, technical advice, and ongoing service.
What We Supplied
A complete thermal processing line built around a Φ 1×12m electric-heated stainless steel rotary kiln.

How the Process Works
| Stage | What Happens |
|---|---|
| Feed | Material enters through a controlled feed system |
| Heating | Electric heating raises temperature in controlled zones |
| Thermal treatment | Material undergoes calcination, drying, or reaction under controlled atmosphere |
| Cooling | Product is cooled before discharge |
| Discharge | Processed material exits the kiln |
| Gas treatment | Exhaust gases pass through treatment before release |
The rotary kiln operates on a simple principle: the drum rotates slowly, and internal lifting flights shower the material through the heated zone. This ensures uniform contact between the material and the heat source—consistent processing without hot spots.
Trial Run Results: Performance Confirmed
The trial run was completed successfully. Key results:
| Performance Metric | Result |
