Henan Hongke Heavy Machinery Co., Ltd. is pleased to announce that a Φ 3×36m rotary kiln production line for non-ferrous metal smelting has successfully passed acceptance at a customer site in Ganzhou, Jiangxi Province, China. This is a brand-new installation—not a refurbishment, not an upgrade of old equipment—delivered as a complete, engineered production line.
Project Background: Smelting in Ganzhou
Ganzhou is known as "the capital of rare earths" and is a major hub for non-ferrous metal smelting in southern China. The region processes tungsten, rare earths, and other metals, and local smelters require reliable thermal equipment for roasting, calcination, and smelting operations.
Our customer operates a non-ferrous metal smelting facility in Ganzhou. They needed a new rotary kiln line to handle their specific feed material and production targets. Their existing equipment was outdated and could not consistently meet quality or throughput requirements.
They came to us with clear needs:
Consistent product quality – stable smelting results
Reliable continuous operation – 24/7 production
Precise temperature control – critical for metal recovery
Environmental compliance – dust and gas emissions within regulations
Brand-new equipment – no used or refurbished machinery
A complete line – not just a kiln
Why This Customer Chose Henan Hongke Machinery
After evaluating several suppliers, the customer selected Henan Hongke Heavy Machinery for several reasons:
1. Experience with Non-Ferrous Smelting
Non-ferrous metal smelting involves high temperatures, aggressive materials, and precise process control. We demonstrated our understanding of these demands and our ability to design a kiln that meets them.
2. Custom-Engineered for Their Material
We don't sell generic kilns. Our engineering team designed this Φ 3×36m kiln around the customer's specific feed characteristics—including particle size, moisture, and chemical composition.
3. Complete, Brand-New System
The customer wanted a purpose-built system, not a refurbished unit or a repurposed cement kiln. We delivered a complete production line, built from the ground up.
4. One-Stop Solution
We supplied the full scope—feed system, kiln, burner, 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 acceptance. We provide spare parts, technical advice, and ongoing service.
What We Supplied
A complete non-ferrous smelting line built around a Φ 3×36m rotary kiln.
| Key Specification | Value |
|---|---|
| Kiln diameter | 3.0 meters |
| Kiln length | 36 meters |
| Application | Non-ferrous metal smelting/roasting |
| Operating temperature | Up to 1,300°C (adjustable) |
| Kiln inclination | 3–4% |
| Rotation speed | Variable frequency drive |
| Drive system | Heavy-duty gear drive with auxiliary motor |
| Sealing system | Labyrinth seals with air purge |
The system includes:
Controlled feed system for consistent material entry
Φ 3×36m rotary kiln with high-alumina refractory lining
Multi-fuel burner (gas or pulverized coal)
Dust collection system (cyclone + bag filter)
Discharge and cooling system
PLC-based controls with temperature monitoring and data logging
How the Smelting Process Works
| Stage | What Happens |
|---|---|
| Feed | Raw material enters through a controlled feed system |
| Heating | Material is gradually heated as it moves through the kiln |
| Reaction | At high temperature, chemical reactions occur—metals are reduced or roasted |
| Discharge | Processed material exits the kiln |
| Gas treatment | Exhaust gases pass through dust collection before release |
The rotary kiln operates on a simple principle: the drum rotates slowly, and internal lifting flights shower the material through the hot gas stream. This ensures uniform contact between the material and the heat source—consistent processing without hot spots.
Acceptance Results: Performance Confirmed
The system has successfully passed acceptance. Key results:
| Performance Metric | Result |
|---|---|
| Installation completion | On schedule |
| Mechanical testing | Smooth operation, normal bearing temperatures |
| Temperature control | Achieved setpoints within specified tolerance |
| Product quality | Met customer specifications |
| Emission compliance | Dust and gas emissions within regulatory limits |
| Acceptance | Passed—customer approved |
The customer has formally accepted the system and it is now in production.
