Henan Hongke Heavy Machinery Co., Ltd. is pleased to announce that a 120-ton-per-day sludge incineration rotary kiln production line has been successfully commissioned and is now in operation at a customer site in Jiujiang, Jiangxi Province, China. This is a brand-new installation—not a refurbishment, not an upgrade of old equipment.
Project Background: Sludge Treatment in Jiujiang
Jiujiang, located along the Yangtze River in northern Jiangxi Province, has a strong industrial base that includes petrochemicals, chemicals, and manufacturing. These industries generate significant volumes of industrial and municipal sludge that require safe, effective treatment.
Our customer operates a waste treatment facility in Jiujiang. They handle sludge from local industrial and municipal sources—material that is wet, variable in composition, and challenging to process. Their existing treatment methods were struggling to keep up with growing volumes, and disposal costs were rising.
They needed a reliable thermal treatment system that could:
Handle wet, sticky sludge consistently
Reduce sludge volume significantly
Meet strict environmental emission standards
Operate continuously with minimal downtime
Be brand-new—not a used or refurbished unit
Include the complete line—not just the kiln
Why This Customer Chose Henan Hongke Machinery
After evaluating several suppliers, the customer selected Henan Hongke Heavy Machinery for several reasons:
1. Experience with Sludge Processing
Sludge is not an easy material. It's wet, it sticks to equipment, and it varies from batch to batch. We demonstrated our understanding of these challenges and our ability to design a kiln that handles them reliably.
2. Custom-Engineered for Their Sludge
We don't sell generic kilns. Our engineering team designed this 120 TPD line around the customer's specific sludge characteristics—moisture content, organic fraction, and target throughput.
3. Complete, Brand-New System
The customer wanted a purpose-built system, not a refurbished unit or a repurposed cement kiln. We delivered a complete production line, built from the ground up.
4. One-Stop Solution
We supplied the full scope—feed system, kiln, burner, dust collection, discharge, and controls. The customer didn't have to coordinate multiple suppliers.
5. Long-Term Support
The customer wanted a partner who would be there after commissioning. We provide spare parts, technical advice, and ongoing service.
What We Supplied
A complete sludge incineration line designed for 120 tons per day.
| Key Specification | Value |
|---|---|
| Capacity | 120 tons per day |
| Application | Sludge incineration / thermal treatment |
| Kiln type | Rotary kiln with refractory lining |
| Operating temperature | Up to 1,200°C (adjustable by zone) |
| Drive system | Heavy-duty gear drive with auxiliary motor |
| Sealing system | Labyrinth seals with air purge |
| Control | PLC-based with temperature monitoring |
The system includes:
Controlled feed system for consistent material entry
Rotary kiln with high-alumina refractory lining
Multi-fuel burner (gas or pulverized coal)
Secondary combustion chamber for complete gas burnout
Dust collection system (cyclone + bag filter)
Discharge and cooling system
PLC-based controls with full data logging
How the Sludge Incineration Process Works
| Stage | What Happens |
|---|---|
| Feed | Wet sludge enters through a controlled feed system |
| Drying | Material is heated; moisture evaporates |
| Incineration | Organic content is destroyed at high temperature |
| Discharge | Treated material exits the kiln |
| Gas treatment | Exhaust gases pass through secondary combustion and dust collection before release |
The rotary kiln operates on a simple principle: the drum rotates slowly, and internal lifting flights shower the material through the hot gas stream. This ensures uniform contact between the sludge and the heat source—consistent treatment without hot spots or incomplete processing.
Actual Results: Now in Production
The system has been successfully commissioned and is now in production. Key results:
| Performance Metric | Result |
|---|---|
| Production capacity | 120 TPD achieved and sustained |
| Operational stability | Continuous operation with minimal interruptions |
| Volume reduction | Significant reduction achieved |
| Emission compliance | Dust and gas emissions within regulatory limits |
| Product quality | Treated material meets disposal requirements |
| Customer feedback | Positive—system performs as expected |
The customer has expressed satisfaction with the system's performance and reliability.
Customer Feedback
