This used Φ2.5m×50m rotary kiln is specially designed for hazardous aluminum ash treatment and resource recovery. It has a stable capacity of 80–120 tons per day with a calcination temperature range of 1100–1350℃, delivering high aluminum recovery rate and low energy consumption. Equipped with a cooler, flexible sealing, hydraulic rollers and automatic control system, the kiln is in good working condition with intact refractory lining. It can be installed and put into production quickly, making it a cost-effective choice for aluminum processing and hazardous waste recycling enterprises worldwide.

This Φ2.5m × 50m rotary kiln is purpose-built for the harmless disposal and resource recovery of hazardous aluminum ash. Previously installed at a licensed aluminum ash treatment facility in Hebei Province, the unit has been in stable operation for three years with regular professional maintenance, and all critical components have been inspected and replaced in line with industry standards. Having completed its production run, the kiln is now ready for on-site dismantling, as we have completed full repurchase procedures and can arrange professional dismantling, packing and shipment at any time. Proven in real-world aluminum ash processing applications, the kiln fully conforms to technical standards set by the International Aluminium Institute (IAI), with a diameter of 2.5m, length of 50m and an integrated single-pass cooler, delivering a design capacity of 80–100 TPD of aluminum ash. In actual operation, it consistently processed over 100 tons per day of both primary and secondary aluminum ash with stable performance, with the calcination temperature controllable within 1,100–1,350°C to ensure full decomposition of hazardous components such as fluorides and nitrides, achieving an aluminum recovery rate of over 85%. The treated residue fully complies with EU REACH and US EPA hazardous waste regulations, making it suitable for direct use in construction materials and refractory production. The kiln speed is adjustable from 0.1–1.5 rpm, with the main drive powered by a 55 kW motor supported by a 15 kW auxiliary motor to prevent material buildup during power outages, while graphite block flexible seals at the inlet and outlet keep air leakage below 5%, greatly improving thermal efficiency. The配套 cooler rapidly cools the discharge material from over 1,000°C to below 100°C for downstream handling, and the overall thermal efficiency is 18% higher than conventional rotary kilns of the same size, with fuel consumption as low as 120–150 Nm³ of natural gas (or equivalent fuel) per ton, well below the industry average. Designed for strict hazardous waste environmental compliance, the kiln is pre-equipped with connections for bag filtration, desulfurization, denitrification and activated carbon adsorption systems, with emissions during operation fully meeting China’s GB 25465-2010 standard and readily adaptable to meet EU, Southeast Asian and Middle Eastern environmental requirements. The kiln features a dual lining of high-alumina refractory bricks and wear-resistant castable, with the current remaining lining thickness at approximately 70% of the original, providing a service life of at least five more years without replacement and significantly lowering initial capital investment. The complete unit includes the main rotary kiln, single-tube cooler, kiln head burner, feeding system, hydraulic thrust roller assembly, full drive system, automated electrical control cabinet and a spare parts package valued at RMB 120,000, with all systems in good running condition and ready for immediate production after installation and commissioning without the need for additional core components. Priced at only 35–40% of a new equivalent unit, this kiln saves the buyer over USD 250,000 in upfront costs while eliminating commissioning risks and shortening project lead times. The kiln remains at its original site in Hebei, where on-site inspections or virtual video surveys can be arranged anytime, and full documentation including operation records, production data and environmental test reports is available. We support the full export process, including professional dismantling and packing, customs clearance documentation, international logistics coordination, on-site installation and commissioning, and operator training. To facilitate overseas customs clearance, we can provide CE Declaration of Conformity, material certificates and hazardous waste treatment equipment qualifications as required, and the control system supports bilingual Chinese-English operation with internationally standardized logic for easy use by foreign personnel. For aluminum processors, hazardous waste treatment operators and recycling enterprises, this well-proven kiln represents a highly cost-effective entry into aluminum ash resource utilization, shortening project timelines by at least three months compared to new equipment with full investment payback typically achieved within 6–8 months of production.
