Copper Wire Granulator

So the Guidetti machine has a zig zag feature? I have yet to personally see their machines in action but all of the videos I've seen do not have this feature. It's a feature that allows larger granules to exit the machine after leaving the granulator. The material that is still attached to insulation and finer wire is sent on to the turbo for further processing and then onto the seperation board. In the end, there are three products: the larger granules of copper from the zig zag, the finer copper from the seperation table and the fluff. If there are other machines with this feature, I'd be very interested in learning more about them. Do you know where I could find more info? Thanks Rewire.
