Henan Hongke Heavy Machinery Co., Ltd. just finished installing a Φ 2.8×30m rotary kiln for iron powder calcination in Qingdao, Shandong. The system is ready to run. Here's the story.
What the Customer Needed
This customer makes iron powder for powder metallurgy, magnets, and welding electrodes. They needed a new calcination line—their old equipment couldn't deliver consistent quality or meet their throughput targets.
They needed:
Consistent product quality – stable chemical and physical properties
24/7 operation – reliable, continuous production
Precise temperature control – critical for iron powder
Dust control – meets environmental rules
Brand-new equipment – no used machines
A complete line – not just a kiln
Why They Chose Us
They looked at several suppliers. Here's why they picked us:
We know metal powder processing – precise temps, atmosphere control
We built it for their material – sized for their powder, their moisture, their target
We supplied the whole line – kiln, burner, dust collection, controls, everything
We stay after installation – spare parts, technical help, maintenance advice
What We Supplied
A complete calcination line built around a Φ 2.8×30m rotary kiln.
| Key Spec | Value |
|---|---|
| Diameter | 2.8 m |
| Length | 30 m |
| Application | Iron powder calcination |
| Temp | Up to 1,100°C (zoned control) |
| Drive | Heavy-duty gear with backup |
The system includes:
Controlled feed system
Φ 2.8×30m rotary kiln with high-alumina refractory
Multi-fuel burner (gas or coal)
Dust collector (cyclone + bag filter)
Discharge and cooling system
PLC controls with temperature monitoring
How It Works – Simple and Effective
| Stage | What Happens |
|---|---|
| Feed | Iron powder enters through a controlled feeder |
| Heating | Material heats up as it moves through the kiln |
| Calcination | At high temp, impurities are removed and properties develop |
| Discharge | Calcined product exits at the lower end |
| Gas treatment | Exhaust goes through dust collection before release |
The drum rotates slowly. Internal flights lift and shower the material through the hot gas stream. Uniform contact, consistent calcination, no hot spots.
Installation Results – Completed
| What We Checked | Result |
|---|---|
| Installation | Completed on schedule |
| Mechanical alignment | Verified to spec |
| No-load testing | Smooth, normal bearing temps |
| System integration | All components connected and tested |
| Operational readiness | Ready for commissioning |
What the Customer Got
| Benefit | Why It Matters |
|---|---|
| Consistent product quality | Stable chemical and physical properties |
| Reliable operation | Built for continuous production, less downtime |
| Precise temperature control | Multi-zone monitoring for optimal calcination |
| Environmental compliance | Dust under control |
| Lower operating costs | Optimized fuel use, less maintenance |
| Full support | Installation, commissioning, spare parts, technical help |
| Brand-new reliability | No hidden wear, full service life ahead |
