Henan Hongke Heavy Machinery Co., Ltd. is pleased to announce the successful trial run of a Φ 2.0×20m rotary dryer production line for sludge drying at a customer site in Shandong Province, China. This is a brand-new installation—not a refurbishment, not an upgrade of old equipment—delivered as a complete, engineered drying solution.
Project Background: Sludge Drying in Shandong
Shandong Province is one of China's largest industrial and agricultural regions, with a strong presence in chemicals, petrochemicals, papermaking, and municipal wastewater treatment. These sectors generate significant volumes of sludge—a wet, sticky byproduct that requires effective dewatering and drying before disposal, reuse, or further processing.
Our customer in Shandong operates a sludge treatment facility. They handle sludge from local industrial and municipal sources. Their existing drying equipment was struggling—output moisture was inconsistent, throughput was too low, and maintenance costs were climbing.
They came to us with clear requirements:
Consistent drying performance – stable output moisture content
High throughput – matching their production targets
Reliable continuous operation – 24/7 production with minimal downtime
Environmental compliance – dust and odor control
Brand-new equipment – no used or refurbished machinery
Complete line – not just a dryer, but the full system
Why This Customer Chose Henan Hongke Machinery
After evaluating several suppliers, the customer selected Henan Hongke Heavy Machinery for several compelling reasons:
1. Experience with Sludge Drying
Sludge is not an easy material. It's wet, it sticks to equipment, and it varies in composition. We demonstrated our understanding of these challenges and our ability to design a dryer that handles them reliably.
2. Custom-Engineered for Their Sludge
We don't sell generic dryers. Our engineering team designed this Φ 2.0×20m dryer 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 dryer. We delivered a complete production line, built from the ground up.
4. One-Stop Solution
We supplied the full scope—feed system, rotary dryer, heating system, 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 drying line built around a Φ 2.0×20m rotary dryer.
| Key Specification | Value |
|---|---|
| Dryer diameter | 2.0 meters |
| Dryer length | 20 meters |
| Application | Sludge drying |
| Heating method | Direct or indirect (configured to customer requirements) |
| Drive system | Heavy-duty gear drive with variable frequency control |
| Sealing system | Advanced seals for dust and odor containment |
| Control | PLC-based with temperature and moisture monitoring |
The system includes:
Controlled feed system for consistent material entry
Φ 2.0×20m rotary dryer with custom internal flights for sludge
Heating system with precise temperature control
Dust collection system (cyclone + bag filter)
Discharge and conveying system
PLC-based controls with full data logging
How the Sludge Drying Process Works
| Stage | What Happens |
|---|---|
| Feed | Wet sludge enters through a controlled feed system |
| Drying | Material is tumbled through the hot gas stream; moisture evaporates |
| Discharge | Dried sludge exits at the lower end with target moisture content |
| Dust control | Exhaust gas passes through cyclone and bag filter |
The rotary dryer operates on a simple principle: the drum rotates slowly, and internal lifting flights shower the sludge through the hot gas stream. This ensures uniform contact between the material and the drying air—consistent moisture removal without hot spots or over-drying.
Trial Run Results: Performance Confirmed
The trial run was completed successfully. Key results:
| Performance Metric | Result |
|---|---|
| Output moisture content | Consistent, meeting customer specifications |
| Throughput | Achieved target capacity |
| Operational stability | Continuous operation with minimal interruptions |
| Dust emissions | Within regulatory limits |
| System integration | All components working together as designed |
| Customer feedback | Positive—system performs as expected |
The system is now ready for continuous production.
