Z Series Vertical Shredders are mostly recommended for applications processing pre-shredded metal scrap from twin shaft shredding systems. These machines aggressively size reduce and densify pre-shredded material whilst liberating the various different fractions, allowing for better separations and reduced transportation costs.

The breakers in the upper part of the chamber smash the material until it is small enough to enter the gap between the milling rings and chamber liners. When the material enters the second stage the milling rings impact, grind and roll the material into clean, dense nuggets. When milled into small enough pieces, the balled-up material falls into the lower chamber and is ejected by the discharge paddles. The three above stages create a product which is both clean and of high bulk density suitable for transportation.
