Henan Hongke Heavy Machinery Co., Ltd. just completed installation and commissioning of a rotary dryer for sand in Russia. The system is now running. Here's the story.
What the Customer Needed
This customer produces building materials in Russia. They need dry sand for concrete and asphalt—but Russian winters are tough on equipment. Their old dryer couldn't keep up, and output moisture was all over the place.
They needed:
Consistent drying – stable moisture, year-round
Cold-weather reliability – works in sub-zero temperatures
High throughput – meets production targets
Dust control – meets environmental rules
Brand-new equipment – no used machines
A complete system – not just a dryer
Why They Chose Us
They talked to several suppliers. Here's why they picked us:
We know cold climates – freezing material, moisture migration, thermal efficiency
We built it for their sand – sized for their particles, their moisture, 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 sand drying system built around a rotary dryer.
| Key Spec | Value |
|---|---|
| Application | Sand drying |
| Dryer type | Rotary dryer with lifting flights |
| Heating | Direct or indirect (configured to needs) |
| Drive | Heavy-duty gear with variable frequency |
| Seals | Advanced – designed for cold weather |
| Control | PLC with temperature and moisture monitoring |
The system includes:
Controlled feed system
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 sand enters through a controlled feeder |
| Drying | Material tumbles through hot gas – moisture evaporates |
| Discharge | Dry sand exits at the lower end |
| Dust control | Exhaust goes through cyclone and bag filter |
The drum rotates slowly. Internal flights lift and shower the sand through the hot gas stream. Uniform contact, consistent drying, 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 |
|---|---|
| Output moisture | Consistent, meets spec |
| Throughput | Target capacity achieved |
| Operational stability | Continuous, minimal interruptions |
| Dust emissions | Within regulatory limits |
| Cold-weather performance | Stable in sub-zero conditions |
| Customer feedback | Positive – works as expected |
What the Customer Says
"The dryer runs smooth. No clogging like before, and the output moisture is consistent—even in winter. Dust control works, and we're hitting our targets." — Operations Manager, Russia
What the Customer Got
| Benefit | Why It Matters |
|---|---|
| Consistent product quality | Stable moisture, batch after batch |
| Cold-weather reliability | Designed for Russian winters |
| High throughput | Meets production targets |
| Environmental compliance | Dust 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 |
Building Long-Term Partnerships
A successful commissioning is just the start. Our commitment to the Russian 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.
