Henan Hongke Heavy Machinery Co., Ltd. is proud to share the success of a recently completed 300-ton-per-day lime rotary kiln project in Heshun County, Shanxi Province, China. This is a modern, high-efficiency system that is already delivering real results for our customer.
Why This Customer Chose Us
Our customer in Heshun is a well-established industrial operator serving the steel, calcium carbide, and building materials sectors in northern China. Demand for high-quality lime was growing fast, but their old production methods couldn't keep up.
They needed a reliable partner who could:
Deliver consistent, high-quality lime – meeting reactivity specs for steelmaking and chemicals
Reduce fuel costs – their old equipment was wasting energy
Meet environmental standards – dust emissions had to be controlled
Run 24/7 with minimal downtime – no excuses
After evaluating several suppliers, they chose Henan Hongke Heavy Machinery because we offered a complete, custom-engineered solution—not just a machine, but a system designed for their specific needs and site conditions.
What We Supplied
A complete lime production line built around a Φ 3.3×60m rotary kiln.
| Key Feature | Specification |
|---|---|
| Kiln size | 3.3 m diameter × 60 m length |
| Capacity | 300 tons per day |
| Operating temperature | 950–1,250°C |
| Fuel | Coal, gas, or mixed fuels |
The system includes:
Vertical preheater – captures waste heat, preheats limestone to ~900°C, cuts fuel use by ~30%
Φ 3.3×60m rotary kiln – main calcination unit with high-alumina refractory lining
Vertical cooler – quenches lime fast, preserves reactivity, recovers heat
Multi-channel burner – runs on coal, gas, or mixed fuels
Multi-stage dust collector – cyclone + bag filter, emissions under 30–50 mg/Nm³
PLC/DCS automation – monitors temperature, feed rate, speed, and emissions automatically
How It Works – Simple and Reliable
| Stage | What Happens |
|---|---|
| Preheat | Limestone heated to ~900°C using waste gas from the kiln |
| Calcination | 1,100–1,250°C in the kiln – limestone turns to quicklime |
| Cooling | Lime cooled from 1,100°C to <100°C – locks in reactivity |
| Dust control | Gases cleaned before they leave the stack |
Why This Kiln Is the Right Choice
| Feature | Why It Matters |
|---|---|
| 60m length | More residence time – complete calcination every time |
| Preheater | Saves ~30% on fuel – lower operating costs |
| Fast cooler | Keeps lime reactive – higher value for customers |
| Advanced seals | Less heat loss, less dust – cleaner operation |
| Automation | Consistent quality, less manual work |
What the Customer Has Achieved
Once fully operational, this 300 TPD lime plant delivers:
| Benefit | Value |
|---|---|
| 300 tons/day capacity | Meets growing demand from local industries |
| High-quality lime (reactivity ≥320ml) | Satisfies steelmaking and chemical specs |
| ~30% fuel savings | Preheater technology cuts energy costs |
| 24/7 reliability | Designed for continuous operation |
| Clean operation | Emissions meet national standards |
| Lower labor costs | Automation reduces manual intervention |
