Henan Hongke Heavy Machinery Co., Ltd. is pleased to share an update on a Φ 1.2×22m electric-heated rotary kiln for spent battery recycling at a customer site in Xiangtan, Hunan Province, China. The system has been running smoothly since commissioning. This is a brand-new installation—not a refurbishment, not an upgrade of old equipment.
Project Background: Battery Recycling in Hunan
With the rapid growth of electric vehicles and consumer electronics, spent lithium-ion batteries have become one of the fastest-growing waste streams in China. Proper recycling is essential—not only to prevent environmental harm but also to recover valuable metals like lithium, cobalt, nickel, and manganese.
Hunan Province has become a major hub for battery recycling, with several facilities focused on secondary regeneration of battery materials. Our customer in Xiangtan operates in this sector, recovering valuable metals from spent batteries through thermal processing.
They came to us with clear requirements:
Consistent thermal treatment – stable results for downstream recovery
Electric heating – clean operation, precise temperature control
Reliable continuous operation – 24/7 production
Environmental compliance – emission control for safe processing
Brand-new equipment – no used or refurbished machinery
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 Electric-Heated Kilns
Electric heating offers advantages for battery recycling—no combustion gases, precise temperature control, and clean operation. We demonstrated our ability to design and build an electric-heated rotary kiln that meets these requirements.
2. Custom-Engineered for Their Material
We don't sell generic kilns. Our engineering team designed this Φ 1.2×22m kiln around the customer's specific feed material—spent battery components requiring controlled thermal treatment.
3. Complete, Brand-New System
The customer wanted a purpose-built system, not a refurbished unit or a repurposed kiln. We delivered a complete production line, built from the ground up.
4. One-Stop Solution
We supplied the full scope—feed system, kiln, heating system, atmosphere control, 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 battery recycling line built around a Φ 1.2×22m electric-heated rotary kiln.

Discharge and cooling system
Exhaust gas treatment system
PLC-based controls with full data logging
How the Battery Recycling Process Works
| Stage | What Happens |
|---|---|
| Feed | Spent battery materials enter through a controlled feed system |
| Heating | Electric heating raises material temperature in controlled zones |
| Thermal treatment | Organic components are removed; metals are prepared for recovery |
| Discharge | Treated material exits the kiln for downstream processing |
| Gas treatment | Exhaust gases pass through treatment before release |
Electric heating offers several advantages for battery recycling:
No combustion gases – clean operation, no contamination from fuel
Precise temperature control – exact setpoints for consistent results
Atmosphere control – inert gas can be used to prevent oxidation
Compact footprint – no burner system or fuel handling equipment
Actual Results: Stable Operation Confirmed
The system has been running smoothly since commissioning. Key results:
| Performance Metric | Result |
|---|---|
| Operational stability | Continuous operation with minimal interruptions |
| Temperature control | Precise setpoints maintained across zones |
| Product quality | Treated material meets downstream recovery requirements |
| Emission compliance | Exhaust treatment meeting regulatory standards |
| Customer feedback | Positive—system performs as expected |
The customer has expressed satisfaction with the system's performance and reliability.
