Air Knife Separator
The Carrier air knife system provides an effective, efficient means of separating heavy metal, stone, plastics,
paper and other debris from aluminum beverage container (UBC) scrap or other low-density materials.
- Process is intended to reduce residual contaminant build-up in the recycled alloy, reduce furnace melt
loss, and recover other recyclable materials from the aluminum such as lead, copper, paper, plastic, etc.
- The principle involves air separation of lighter materials from heavier free-falling materials. A vibratory
feeder is used to transport the material over a high-velocity air knife or curtain. The vibrating action
causes finer, heavier materials to migrate to the bottom of the conveyed bed, where they fall through the
air curtain and are collected below. Aluminum and lighter materials are blown across into a separation hopper,
where the aluminum falls out onto a collection belt. Dust, paper, plastic and other lighter materials are
collected in an exhaust system consisting of a cyclone and/or after-filter.
- The concept provides a 95% efficient means of cleaning the aluminum scrap and recovery of contaminants
with very low energy consumption and low front-end capital expense.
- Designed to process shredded UBC or whole cans.
- Standard systems for 15,000, 30,000, and 45,000 PPH.
- Also removes plastics, paper, and loose dirt from the UBC scrap.
- Operation places no moving parts in contact with material.
- Design of system minimizes loss of UBC scrap.
- Adjustable nozzle assembly for fine-tuning in the field.
- Laboratory system available for demonstration and testing on actual product.
