Henan Hongke Heavy Machinery Co., Ltd. recently commissioned a Φ 1.8×35m rotary kiln for sludge treatment in Fushun, Liaoning. The system has been running smoothly, and the customer is happy. Here's the story.
What the Customer Needed
This customer runs a sludge treatment facility. They handle wet, sticky sludge from local industrial and municipal sources. Their old setup couldn't keep up—equipment clogged, disposal costs kept rising, and emissions were hard to control.
They needed:
A kiln that could handle wet, sticky sludge without constant clogs
Significant volume reduction
Emissions that meet environmental rules
24/7 operation with minimal downtime
Brand-new equipment—no used or refurbished machines
Why They Chose Us
They talked to several suppliers. Here's why they picked us:
We know sludge – it's not like lime or cement; it sticks and varies
We built it for their material – sized for their moisture, their organic content, their target
We supplied the whole line – kiln, burner, dust collection, controls, everything
We stay after commissioning – spare parts, technical help, maintenance advice
What We Supplied
A complete sludge treatment line built around a Φ 1.8×35m rotary kiln.
| Key Spec | Value |
|---|---|
| Diameter | 1.8 m |
| Length | 35 m |
| Application | Sludge treatment |
| Temp | Up to 1,200°C (zoned control) |
| Drive | Heavy-duty gear with backup |
The system includes:
Controlled feed system
Φ 1.8×35m rotary kiln with refractory lining
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 | Wet sludge enters through a controlled feeder |
| Drying | Material heats up – moisture evaporates |
| Calcination | Organics burn off at high temperature |
| Discharge | Treated material exits the kiln |
| 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 treatment, no hot spots.
The Results – Running Steady
The system has been running since commissioning. Here's how it's doing:
| What We Checked | How It Performed |
|---|---|
| Operational stability | Continuous, minimal interruptions |
| Volume reduction | Significant reduction achieved |
| Emissions | Within regulatory limits |
| Product quality | Meets disposal and reuse requirements |
| Customer feedback | Positive – system works as expected |
What the Customer Says
"The kiln has been running smoothly since startup. It handles our sludge without the sticking and clogging we had before. Emissions are under control, and we're finally meeting our treatment targets." — Operations Manager, Fushun
What the Customer Got
| Benefit | Why It Matters |
|---|---|
| Reliable operation | Continuous processing, less downtime |
| Consistent treatment | Uniform results, batch after batch |
| Environmental compliance | Emissions under control |
| Lower disposal costs | Less volume means lower transport and landfill fees |
| Full support | Commissioning, spare parts, technical help |
| Brand-new reliability | No hidden wear, full service life ahead |
Building Long-Term Partnerships
A successful commissioning is just the start. Our commitment to the Fushun customer continues:
Technical support – process advice and troubleshooting
Spare parts – critical components ready to ship
Maintenance guidance – help with preventive maintenance planning
Future cooperation – ready to support growth as their business expands
We're not just a supplier. We're a partner.
