Henan Hongke Heavy Machinery Co., Ltd. recently commissioned a Φ 1.2×22m electric-heated rotary kiln for spent battery recycling in Xiangtan, Hunan. The system is running well. Here's the story.
What the Customer Needed
This customer recycles spent lithium-ion batteries. They recover valuable metals—lithium, cobalt, nickel, manganese—through thermal treatment. Their old setup couldn't deliver consistent results, and they needed tighter control over temperature and atmosphere.
They needed:
Consistent thermal treatment – stable results for downstream recovery
Electric heating – no combustion gases, precise temperature control
Atmosphere control – inert gas capability to protect materials
24/7 operation – reliable, continuous production
Emission control – safe, clean processing
Brand-new equipment – no used machines
A complete line – not just a kiln
Why They Chose Us
They looked at several suppliers. Here's why they picked us:
We know electric-heated kilns – clean operation, precise control, no fuel contamination
We built it for their material – sized for spent battery components
We supplied the whole line – kiln, heating system, atmosphere control, exhaust treatment, controls
We stay after commissioning – spare parts, technical help, maintenance advice
What We Supplied
A complete battery recycling line built around a Φ 1.2×22m electric-heated rotary kiln.
| Key Spec | Value |
|---|---|
| Diameter | 1.2 m |
| Length | 22 m |
| Application | Spent battery recycling |
| Heating | Electric (resistance or induction) |
| Temp | Up to 800–1,000°C |
| Atmosphere | Inert or controlled |
| Drive | Variable frequency control |
The system includes:
Controlled feed system
Φ 1.2×22m electric-heated kiln with refractory lining
Multi-zone electric heating system
Atmosphere control (inert gas capability)
Discharge and cooling system
Exhaust gas treatment
PLC controls with data logging
How It Works – Simple and Clean
| Stage | What Happens |
|---|---|
| Feed | Spent battery materials enter through a controlled feeder |
| Heating | Electric heating raises temperature in controlled zones |
| Thermal treatment | Organics are removed; metals are prepared for recovery |
| Discharge | Treated material exits for downstream processing |
| Gas treatment | Exhaust goes through treatment before release |
Electric heating means no combustion gases, no fuel contamination, and precise temperature control. Inert gas can be used to prevent oxidation—a real advantage for battery materials.
The Results – Running Well
The system has been running since commissioning. Here's how it's doing:
| What We Checked | How It Performed |
|---|---|
| Operational stability | Continuous, minimal interruptions |
| Temperature control | Precise setpoints maintained |
| Product quality | Meets downstream recovery requirements |
| Emissions | Within regulatory limits |
| Customer feedback | Positive – system works as expected |
What the Customer Says
"The electric-heated kiln gives us the control we need. No combustion gases, precise temperatures, and atmosphere control is a real advantage. It's been running steady since startup." — Operations Manager, Xiangtan
What the Customer Got
| Benefit | Why It Matters |
|---|---|
| Clean operation | No combustion gases or fuel contamination |
| Precise temperature control | Multi-zone monitoring for optimal treatment |
| Atmosphere control | Inert gas protects sensitive materials |
| Reliable operation | Built for continuous production, less downtime |
| Environmental compliance | Exhaust treatment meets regulations |
| 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 Xiangtan 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.
