Henan Hongke Heavy Machinery Co., Ltd. just completed a successful trial run of a Φ 2.0×20m rotary dryer for sludge in Shandong, China. The system is ready to run. 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 dryer couldn't keep up—output moisture was inconsistent, throughput was too low, and maintenance costs kept climbing.
They needed:
Consistent drying – stable output moisture
High throughput – meets production targets
24/7 operation – reliable, minimal downtime
Dust and odor control – meets environmental rules
Brand-new equipment – no used machines
A complete line – not just a dryer
Why They Chose Us
They talked to several suppliers. Here's why they picked us:
We know sludge – it's wet, it sticks, it varies
We built it for their material – sized for their moisture, their organics, their target
We supplied the whole line – dryer, heating, dust collection, controls, everything
We stay after commissioning – spare parts, technical help, maintenance advice
What We Supplied
A complete sludge drying line built around a Φ 2.0×20m rotary dryer.
| Key Spec | Value |
|---|---|
| Diameter | 2.0 m |
| Length | 20 m |
| Application | Sludge drying |
| Heating | Direct or indirect (configured to needs) |
| Drive | Heavy-duty gear with variable frequency |
| Seals | Advanced – dust and odor containment |
| Control | PLC with temperature and moisture monitoring |
The system includes:
Controlled feed system
Φ 2.0×20m rotary dryer with custom internal flights
Heating system with precise temperature control
Dust collector (cyclone + bag filter)
Discharge and conveying
PLC controls with data logging
How It Works – Simple and Effective
| Stage | What Happens |
|---|---|
| Feed | Wet sludge enters through a controlled feeder |
| Drying | Material tumbles through hot gas – moisture evaporates |
| Discharge | Dry sludge exits at the lower end |
| Dust control | Exhaust goes through cyclone and bag filter |
The drum rotates slowly. Internal flights lift and shower the sludge through the hot gas stream. Uniform contact, consistent drying, no hot spots.
Trial Run Results – Passed
The trial run was completed successfully. Here's how it performed:
| What We Checked | Result |
|---|---|
| Output moisture | Consistent, meets spec |
| Throughput | Target capacity achieved |
| Operational stability | Continuous, minimal interruptions |
| Dust emissions | Within regulatory limits |
| System integration | All components working together |
| Customer feedback | Positive – works as expected |
What the Customer Says
"The dryer runs smooth. No sticking or clogging like before. Output moisture is consistent, and the dust control works. We're hitting our targets." — Operations Manager, Shandong
What the Customer Got
| Benefit | Why It Matters |
|---|---|
| Consistent product quality | Stable moisture, batch after batch |
| High throughput | Meets production targets |
| Reliable operation | Built for continuous production, less downtime |
| Environmental compliance | Dust and odor under control |
| Lower operating costs | Efficient drying, less fuel |
| Full support | Commissioning, spare parts, technical help |
| Brand-new reliability | No hidden wear, full service life ahead |
