In a zig-zag channel, an upward air flow separates light (film, dust, label) and heavy (flake) material by density difference.
A zig-zag separator generates an upward air flow within a vertical zig-zag channel. Light items (film, label, dust) are carried upward by the air, while heavy items (flake, rigid plastic) fall down. This achieves a clean separation based on density difference.
The zig-zag separator is a classifier that works with an upward air flow; it separates light materials such as dust, labels and film fragments from heavy flake. It mostly works after crushing or washing, complementing mechanical screening units such as the star screen and the ballistic separator.
