Second-hand Lithium Carbonate Rotary Kiln

1. Equipment Overview

The second-hand lithium carbonate rotary kiln is the core calcination equipment for lithium salt production. It is mainly applied to high-temperature roasting, crystal transformation and acidification reaction of lithium ores such as spodumene and lepidolite, serving as essential heavy-duty equipment in the new energy lithium battery material industry chain.

2. Core Application & Process

- High-temperature phase transformation roasting: Heat spodumene to 900~1200℃ to complete crystal form conversion, with a material conversion rate over 98%.

- Acidification roasting: The roasted ore powder reacts with concentrated sulfuric acid at 250~300℃ to produce soluble lithium sulfate.

- Applicable raw materials: Spodumene, lepidolite, petalite and other lithium concentrates.

3. Common Specifications (Secondary Market)

- Small test type: Φ0.6×6m ~ Φ1.2×12m

- Medium-scale production type: Φ2.5×40m ~ Φ3.2×50m

- Large production line type: Φ4.2×60m ~ Φ5.0×90m

- Heating methods: Natural gas firing, coal firing, electric heating.

4. Price Range (2026)

- Small electric heating kiln: 10,000~50,000 RMB

- Medium gas/coal-fired kiln: 300,000~800,000 RMB (price varies by equipment condition and service life)

- Large complete production line kiln: 1,000,000~3,000,000 RMB (complete supporting facilities included)

- Pricing standard: Calculated by weight at 4,500~5,000 RMB per ton or priced as a complete set.

5. Advantages of Second-hand Equipment

- Cost-effective: The purchase cost is 40%~70% lower than new equipment.

- Fast commissioning: Sufficient spot supply and short installation cycle for rapid production launch.

- Stable performance: Well-maintained second-hand units deliver operational performance close to new equipment.

6. Key Selection Criteria

1. Lining: Inspect abrasion, shedding and ring formation of refractory bricks and castables.

2. Transmission system: Check operating conditions of supporting rollers, gears, reducers and motors.

3. Sealing performance: Ensure reliable sealing at kiln head and tail to prevent air leakage and heat loss.

4. Control system: Verify intact functions of temperature control, frequency conversion and monitoring instruments.

5. Brand & Origin: Prioritize formal manufacturer products with reliable quality.

7. Main Equipment Sources

- Phased-out equipment from lithium salt and lithium battery enterprises due to technological upgrading, shutdown or industrial restructuring.

- Idle equipment from mining, metallurgy and chemical processing enterprises.
