Henan Hongke Heavy Machinery Co., Ltd. is pleased to report on the successful installation of a Φ 2.8×17.5m stainless steel rotary dryer at a customer site in Chizhou, Anhui Province, China. This is a brand-new system—not a refurbishment—engineered specifically for high-purity alumina drying applications.
Why This Customer Chose Henan Hongke Machinery
Our customer in Chizhou operates in the advanced materials sector, processing alumina for high-end ceramic and electronic applications. Product purity is absolutely critical—any contamination can ruin the final product quality. The customer needed a drying system that could handle their material safely, maintain strict hygiene standards, and run continuously.
After evaluating several suppliers, they chose Henan Hongke Heavy Machinery for several key reasons:
1. Stainless Steel Construction for Purity
Alumina processing demands equipment that won't introduce contamination. Our dryer is fabricated from stainless steel (304 or 316L, selected based on the specific chemical environment). Unlike carbon steel, stainless steel resists corrosion and rust, ensuring the alumina product stays clean throughout the drying process .
2. Custom-Engineered for Their Material
We don't sell "one-size-fits-all" equipment. Our engineering team designed the internal lifting flights specifically for alumina's flow characteristics—ensuring uniform tumbling and consistent drying without material buildup . The Φ 2.8×17.5m configuration provides the right residence time for their target throughput.
3. Proven Expertise, Not Just a Machine
Henan Hongke Heavy Machinery has been designing and manufacturing industrial rotary equipment since 2006. We serve customers across Asia, Africa, the Middle East, and beyond—with a focus on practical solutions that actually work in real production environments .
4. Long-Term Commitment
The customer chose us because we don't disappear after delivery. We provide installation guidance, commissioning support, spare parts availability, and ongoing technical assistance. They knew they were getting a partner, not just a supplier.
What We Delivered
A complete alumina drying system built around a Φ 2.8×17.5m stainless steel rotary dryer.
| Key Specification | Value |
|---|---|
| Dryer diameter | 2.8 meters |
| Dryer length | 17.5 meters |
| Material of construction | 304 or 316L stainless steel |
| Heating method | Direct or indirect (configured to customer requirements) |
| Capacity | Custom-engineered to customer target |
| Rotation speed | Variable frequency drive |
| Sealing system | Sanitary seals at feed and discharge ends |
The system includes:
Stainless steel dryer shell – corrosion-resistant, maintains product purity
Custom internal lifting flights – designed for alumina flow characteristics
Heating system – with precise temperature control
Multi-stage dust collection – cyclone + bag filter for clean operation
PLC-based controls – with real-time monitoring and data logging
How the Dryer Works
| Stage | What Happens |
|---|---|
| Feed | Alumina enters the dryer through a sealed feed housing |
| Tumbling & Heating | Lifting flights shower material through the hot gas stream; moisture evaporates |
| Discharge | Dried product exits at the lower end with target moisture content |
| Dust control | Exhaust gas passes through cyclone and bag filter; fine particles are captured |
The drum rotates slowly, and the internal flights lift and shower the material through the hot gas stream. This ensures uniform contact between the alumina particles and the drying air—consistent moisture removal without hot spots .
What This Means for Our Customer
| Benefit | Value |
|---|---|
| Product purity | Stainless steel construction prevents contamination |
