Henan Hongke Heavy Machinery Co., Ltd. is pleased to announce the successful shipment of a Φ 1.8×12m electromagnetic heating rotary dryer for gypsum processing to a customer 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: Gypsum Drying in Russia
Russia has abundant gypsum reserves and a growing construction materials sector. Gypsum is used in plasterboard, drywall, cement additives, and agricultural soil conditioners. Before it can be used, raw gypsum must be dried to remove moisture—typically from 10–20% down to below 1%—while preserving its chemical properties.
Our customer in Russia operates in the building materials sector. They needed a reliable drying system that could handle gypsum consistently while meeting strict quality standards. Their existing equipment could not deliver the required output moisture or throughput.
They came to us with clear requirements:
Consistent drying performance – stable output moisture content
Electromagnetic heating – clean, efficient, precise temperature control
Reliable cold-weather operation – designed for Russian winters
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. Electromagnetic Heating Technology
Electromagnetic heating offers significant advantages over conventional combustion-based drying:
Higher thermal efficiency – heat is generated directly in the dryer shell
Precise temperature control – ±1–5°C accuracy for consistent product quality
No combustion gases – clean operation, no contamination
Compact footprint – no burner system or fuel handling equipment
We demonstrated our expertise in this technology and its suitability for gypsum drying.
2. Experience with Cold-Climate Drying
Russia's winters are harsh. Equipment that works in mild climates often fails in sub-zero temperatures. We designed this system with cold-weather operation in mind—from material handling to thermal efficiency.
3. Custom-Engineered for Their Gypsum
We don't sell generic dryers. Our engineering team analyzed the customer's gypsum characteristics—particle size, initial moisture, and thermal behavior—before designing the dryer.
4. 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.
5. One-Stop Solution
We supplied the full scope—feed system, rotary dryer, electromagnetic heating system, dust collection, discharge, and controls. The customer didn't have to coordinate multiple suppliers.
6. Long-Term Support
The customer wanted a partner who would be there after delivery. We provide spare parts, technical advice, and ongoing service.

How the Electromagnetic Heating Dryer Works
| Stage | What Happens |
|---|---|
| Feed | Wet gypsum enters through a controlled feed system |
| Heating | Electromagnetic coils induce eddy currents in the dryer shell, generating heat directly |
| Drying | Material is tumbled through the heated drum; moisture evaporates |
| Discharge | Dried gypsum exits at the lower end with target moisture content |
| Dust control | Exhaust gas passes through cyclone and bag filter |
The electromagnetic heating system works on a simple principle: alternating current through induction coils creates a magnetic field, which induces eddy currents in the metallic dryer shell. The shell itself becomes the heat source, transferring thermal energy to the gypsum through conduction and radiation. No combustion, no flue gases, no wasted heat.
