Condition: new, GENERAL Typical of the single-shaft shredders in the ZIS series are their voluminous grinding chambers, the stability of which is ensured by their welded steel construction. The rotor diameter is also generously dimensioned at 457 mm. The rotor widths are 1200, 1500 and 2000 mm. The ZIS series retains all the advantages of the ZSS series: drive via an oversized gearbox, reversible blades, screwed blade holders, robust, external bearings, hydraulic screen basket, easy handling and technically sophisticated control systems. Isdpfoghgdvsx Ag Uoht APPLICATIONS The ZIS series was primarily developed for large-volume hollow bodies: IBCs, garbage cans, pallets, rain barrels, etc. The machine can also be used universally for countless applications in the plastics and wood industries. Like all Zerma shredders, the machines in the ZIS series can also be equipped with various wear options. ADVANTAGES 35% larger grinding chamber volume compared to the ZSS series Internal hydraulic slide Increased slide speed in the return movement Compact dimensions Knife holders screwed into rotor pockets
