Henan Hongke Heavy Machinery Co., Ltd. is pleased to announce the successful installation and commissioning of a rotary dryer for sand processing at a customer site in Russia. This is a brand-new installation—not a refurbishment, not an upgrade of old equipment—delivered as a complete, engineered drying solution.
Project Background: Sand Drying in Russia
Russia's construction and building materials sector requires large volumes of dried sand for concrete production, asphalt mixing, and dry mortar manufacturing. However, Russia's climate presents unique challenges—high moisture content in raw sand, freezing temperatures in winter, and variable material conditions throughout the year.
Our customer, a building materials producer in Russia, needed a reliable drying system that could handle their sand consistently—regardless of the season. Their existing equipment was struggling to meet production targets, and the quality of dried sand was inconsistent.
They came to us with clear requirements:
Consistent drying performance – stable output moisture content, year-round
Reliable cold-weather operation – designed for Russian winters
High throughput – matching their production targets
Environmental compliance – dust control meeting Russian standards
Brand-new equipment – no used or refurbished machinery
Complete system – not just a dryer, but a fully integrated line
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 Cold-Climate Drying
Russia's winters are harsh. Equipment that works in mild climates often fails in sub-zero temperatures. We demonstrated our understanding of cold-weather challenges—material freezing, moisture migration, and thermal efficiency—and designed a system to handle them.
2. Custom-Engineered for Their Sand
We don't sell generic dryers. Our engineering team analyzed the customer's sand characteristics—particle size, initial moisture, and flow properties—before designing the dryer. The internal structure was optimized for their specific material.
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 sand drying system built around a rotary dryer.
| Key Specification | Value |
|---|---|
| Application | Sand drying |
| Dryer type | Rotary dryer with lifting flights |
| Heating method | Direct or indirect (configured to customer requirements) |
| Operating temperature | Adjustable by material and moisture |
| Drive system | Heavy-duty gear drive with variable frequency control |
| Sealing system | Advanced seals for cold-weather operation |
| Control | PLC-based with temperature and moisture monitoring |
The system includes:
Controlled feed system for consistent material entry
Rotary dryer with custom internal flights for sand
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 Sand Drying Process Works
| Stage | What Happens |
|---|---|
| Feed | Wet sand enters through a controlled feed system |
| Drying | Material is tumbled through the hot gas stream; moisture evaporates |
| Discharge | Dried sand 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 sand through the hot gas stream. This ensures uniform contact between the sand particles and the drying air—consistent moisture removal without hot spots or over-drying.
Commissioning Results: Performance Confirmed
The installation and commissioning were 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 |
| Cold-weather performance | Stable operation in sub-zero conditions |
| Customer feedback | Positive—system performs as expected |
The customer has expressed satisfaction with the system's performance and reliability.
