Henan Hongke Heavy Machinery Co., Ltd. recently installed a Φ 2.8×17.5m stainless steel rotary dryer for an alumina processing customer in Chizhou, Anhui. The system is now running. Here's the story.
What the Customer Needed
This customer makes high-purity alumina for ceramics and electronics. Purity is everything – even tiny contamination ruins the product. Their old drying setup couldn't guarantee that. They needed a dryer that could:
Keep the product clean – no rust, no contamination
Handle alumina's specific flow properties
Run continuously without frequent stops
Meet strict hygiene standards
They also wanted a partner they could trust – someone who wouldn't disappear after delivery.
What We Supplied
A complete drying system built around a Φ 2.8×17.5m stainless steel rotary dryer.
| Key Spec | Value |
|---|---|
| Diameter | 2.8 m |
| Length | 17.5 m |
| Material | Stainless steel (304 or 316L) |
| Capacity | Custom-engineered to their target |
| Drive | Variable frequency control |
The package includes:
Stainless steel shell – no rust, no contamination
Custom lifting flights – designed for alumina flow
Heating system with precise temperature control
Dust collector (cyclone + bag filter)
PLC controls with real-time monitoring
How It Works – Simple and Clean
| Stage | What Happens |
|---|---|
| Feed | Alumina enters through a sealed housing |
| Drying | Lifting flights shower material through hot gas – moisture evaporates |
| Discharge | Dry product comes out the lower end |
| Dust control | Exhaust gas goes through cyclone and bag filter – fines are captured |
No hot spots. No contamination. Just consistent, clean drying.
What the Customer Got
| Benefit | Why It Matters |
|---|---|
| Purity protection | Stainless steel stops rust and corrosion |
| Consistent quality | Uniform drying, batch after batch |
| Corrosion resistance | Outperforms carbon steel in chemical environments |
| 24/7 reliability | Built for continuous production |
| Ongoing support | We don't disappear after installation |
