Heavy parts separation
In the heavy parts separation step, No Canary ensures that the coarse, heavy components — primarily metal and housing parts — are separated from the shredded battery material. To explain it clearly: we separate the heavy chunks (such as screws, cell housings, copper/aluminum pieces) from the light, fine components (powder and foil). Early on in the recycling process, we extract all the material that can later be recycled as scrap metal, while at the same time protecting the rest of the process from these coarse parts.
With heavy particle separation, No Canary offers a separate plant section that improves the quality of the end products and increases the efficiency of the plant. We isolate valuable metal parts (which can be resold directly) and reduce the load on the fine processing stage – making the plant more economical and safer.
We supply a modular separation unit that is connected after the pre-module (shredding/drying). This unit usually consists of a zigzag separator and downstream sorting units. First, the mixed material (dry granulate from the shredder) is fed into a vertical zigzag channel through which an air stream flows from bottom to top. This zigzag sifting separates the heavy fraction (heavy parts) from the light fraction by means of air classification: heavy particles (> approx. 5 mm, e.g., metal pieces, dense plastic parts) fall downwards, while lighter particles and films are discharged upwards.
We offer this stage complete with blower, channel, and screw conveyors/chutes for the separated streams. The discharged heavy fraction (typically 5–10 mm pieces of steel, copper, aluminum, hard plastic) can then be further broken down using magnetic separators and eddy current separators: Ferromagnetic components (steel, iron) are removed by a magnetic belt, while the remaining non-ferrous metals (mainly aluminum and copper pieces) are separated from non-conductive plastics by the eddy current separator.
