Henan Hongke Heavy Machinery Co., Ltd. recently delivered a Φ2.0×50m rotary kiln for lime production to a customer in Yunnan, China. The system runs at 100 tons per day. Here's the story.
The Situation: Old Kilns Were Costing Too Much
Our customer in Yunnan runs a lime production plant. They had old vertical kilns that were burning too much fuel, putting out inconsistent quality, and struggling with dust emissions. Operating costs were high, and they were losing customers who needed better lime.
They needed a modern, efficient system that could deliver 100 tons per day of consistent, high-quality quicklime — and keep costs under control.
What We Supplied
We designed a complete lime production line around a Φ2.0×50m rotary kiln.
| Key Spec | Value |
|---|---|
| Diameter | 2.0 m |
| Length | 50 m |
| Capacity | 100 tons/day |
| Operating temp | 950–1,250°C |
| Drive | Heavy-duty gear + backup motor |
The full package includes:
Vertical preheater – catches waste heat, preheats stone, cuts fuel use by ~30%
Φ2.0×50m rotary kiln – main calcination unit with high-alumina refractory lining
Vertical cooler – quenches lime fast, preserves reactivity, recovers heat
Dust collection – cyclone + bag filter keeps emissions under 30–50 mg/Nm³
PLC controls – monitors everything automatically, minimal operator input needed
Why This Kiln Works
| Feature | Benefit |
|---|---|
| 50m length | Enough time for complete burning |
| Preheater | Saves ~30% on fuel |
| Fast cooler | Keeps lime reactive — higher value |
| Good seals | Less heat loss, less dust |
| Automation | Consistent quality, less labor |
Results
Once running, this plant will give our customer:
100 tons per day of consistent, high-quality lime
Lower fuel bills — preheater saves energy
Lower labor costs — automated controls
Clean operation — meets environmental rules
More competitive product — better lime, lower cost
