The Two Shaft Shredders of the ZRM series can be used to pre cut huge volumes of material on hand from film, scrap tires or drums. The Two Shaft Shredders of the ZRM series have a slow operating shredding shaft that is powered either electrically or hydraulically. These shafts work into each and ensure quick completion of the procedure. For a better material feeding, the two shredder shaft can incorporate a hydraulic feeding device. The advantages of this device are the automatic reversal of operation and extremely low costs on wear incurred on the system.
