UBC Aluminum Can Continuous Thermal Decoating Furnace in UAE | Global Case Reference | Henan Yushunxin Heavy Industry Technology (ENV)

ENV-UBC-5000 Turnkey Installation

Delivered, Commissioned & Environmental Tested by Henan Yushunxin (ENV)

Case Background & Scope

Project Implementation & Operational Delivery

In the industrial hub of Sharjah, UAE, a major secondary aluminum smelting foundry faced severe metal dross loss (16% to 18%) and excessive furnace smoke caused by direct charging of shredded used beverage cans (UBCs) containing organic lacquer and vinyl ink.

Henan Yushunxin Heavy Industry Technology (ENV) delivered and installed an industrial-grade continuous rotary thermal decoating kiln capable of processing 5,000 kg/h of shredded UBCs. Operating under micro-negative pressure with precise low-oxygen control (O₂ < 5%), the kiln heats the cans to 510°C, thoroughly vaporizing organic paint layers into high-temperature volatiles.

The volatilized gases are ducted into a secondary thermal afterburner (>850°C) to generate process heat for the kiln, reducing external fuel consumption by over 60%. The decoated aluminum emerges with zero residual carbon, enabling direct furnace melting with less than 0.6% oxidation loss.

Key Engineering & Commissioning Highlights:

✓ Continuous indirect rotary drum with internal flights ensures uniform tumbling without chip jamming.
✓ Vaporized coating gases supply over 60% of total thermal energy required by the kiln.
✓ Dual rare-earth magnetic drums eliminate ferrous tramp metals prior to thermal processing.
✓ Automated emergency water mist quenching and nitrogen purging protect against scrap over-temperature.
✓ Delivers shiny metallic furnace-ready feedstock that speeds up melting furnace cycle times by 35%.
