This set of equipment is currently located in Gansu Province, China.It was previously used mainly for the production of ceramsite sand.The refractory bricks inside the rotary kiln have been completely removed.The kiln is without a kiln head cover and kiln tail cover; both covers were damaged during the removal of refractory bricks by a small excavator and are no longer usable.All other accessories are in good condition.According to infrared flaw detection, the wear on the tyres and supporting rollers is relatively minor and can be re-machined on a lathe if required.The motor and reducer can run normally when powered on.The ovality of the kiln shell meets the Chinese national standards.
Equipment Overview:
• Equipment Type: Rotary kiln for production of lightweight aggregates (expanded clay aggregate, LWA)
• Condition: Second-hand / used equipment
• Location: Gansu Province, China
• Primary Application: Previously used for production of lightweight aggregate sand

When considering the purchase of this second-hand rotary kiln, the following technical aspects should be carefully assessed:
1. Kiln Shell Integrity – Check for cracks, corrosion, and uniformity of the shell. Ensure ovality and structural tolerances meet operational requirements.
2. Riding Rings and Support Rollers – Inspect wear patterns. Minor wear may be corrected via lathe machining. Verify alignment and rotation smoothness.
3. Refractory Lining – The kiln is currently without refractory bricks. Determine the cost and availability of replacement lining materials and installation labor.
4. Kiln Head and Tail Hoods – Missing and damaged. Replacement or reconstruction will be required for full operational use.
5. Drive System – Test motor, gearbox, and coupling for smooth operation under load. Confirm electrical compatibility with local power supply.
6. Temperature Control & Burners – Assess condition of burners, thermocouples, and control instruments if planning kiln firing.
7. Fuel Adaptability – Ensure kiln can accommodate the intended fuel type (coal, gas, oil) or modifications are feasible.
8. Installation & Transport – The kiln is large (147.64 ft × 7.22 ft). Plan for specialized transport, lifting, and foundation construction.
9. Historical Maintenance Records – Review past repairs and operational history to estimate remaining service life and potential hidden costs.
10.Regulatory Compliance & Safety – Ensure kiln operation complies with local safety, emissions, and industrial standards; consider retrofitting safety devices if required.
