Henan Hongke Heavy Machinery Co., Ltd. just finished a brand-new Φ 1.8×40m lime rotary kiln production line for a customer in Jiangxi, China. This is a completely fresh install – not a rebuild, not a patch-up job.
What the Customer Needed
Local industries in Jiangxi – steel, chemicals, building materials – all need good-quality lime. But supply wasn't keeping up. Our customer needed a reliable kiln that could produce consistent lime, day in and day out, without burning through fuel or causing dust problems.
They wanted a purpose-built system, not a recycled cement kiln. And they wanted a partner who could deliver the whole thing – not just the kiln, but everything around it.
What We Delivered
A complete lime production line built around a Φ 1.8×40m rotary kiln.
| Key Spec | Value |
|---|---|
| Diameter | 1.8 m |
| Length | 40 m |
| Temp | Up to 1,250°C |
| Drive | Heavy-duty gear + backup motor |
The full package includes:
Vertical preheater (cuts fuel by ~30%)
Φ 1.8×40m rotary kiln
Vertical cooler (preserves reactivity)
Multi-channel burner (coal or gas)
Dust collector (cyclone + bag filter)
PLC controls with real-time monitoring
How It Works – Simple and Straightforward
| Stage | What Happens |
|---|---|
| Preheat | Limestone heated to ~900°C using waste heat |
| Calcination | 1,100–1,250°C in the kiln – limestone turns to lime |
| Cooling | Lime cooled fast – reactivity locked in |
| Dust control | Gases cleaned before they leave the stack |
The kiln rotates and gently tumbles the material – ensures every particle gets evenly heated. No hot spots, no under-calcined product.
What the Customer Gets
| Benefit | Why It Matters |
|---|---|
| Consistent lime quality | Meets steel and chemical specs |
| ~30% fuel savings | Preheater pays for itself |
| Clean operation | Emissions under control |
| 24/7 reliability | Built to run non-stop |
| Brand-new equipment | No hidden wear, full warranty |
