| Overview |
 |
| The new Zerma ZSS single shaft
shredders have been developed as extremely rugged machines suitable for
heavy duty applications. They can be used to grind various materials such as
lumps, large hollow parts, film, fiber and paper down to a final particle
size of 20 mm. The ZSS series of single shaft shredders comes with numerous
features, innovative controls and different choices of rotors specifically
designed for various material types. All shredders operate at a low speed,
thus operating at lower noise levels. A newly developed and patented ram
feeder is only one of the unique features of the Zerma shredder product
line. |

| Technical details |
|
 |
|
Hydraulic ram construction
The ZSS series shredders benefit from sturdy ram construction incorporating
heavy duty guide bearings and universal couplings for reliable operation.
Serrated ram plate
All ZSS machines feature a serrated ram plate as standard, to allow easy
processing of large awkward pieces such as large purgings blocks and
pallets. |
|
 |
|
Outboard bearings
The heavy duty outboard bearings mounted on the ZSS shredders minimize the
risk of contamination and make a rotor change easier. An optional water
cooling system for the rotor and bearings can be installed as well.
Feed hoppers
Feed hoppers of the ZSS machines can be tailored to suit various
applications. However, the standard hopper is of a suitable design to allow
bulk feeding via tipping skip as well as manual feeding of large bulky barts.
Bulk feeding hopper will customize production as the feeding ram will always
have material in to the rotor. As the machine is fully automatic it is not
possible to over-feed the machine. |
|
 |
|
Cutter blocks
The rotors in the ZSS shredder are equipped with, square cutter blocks.
These cutters make light work of the heaviest pieces.
Importantly, the design allows efficient cutting of material, rather than
hammering and reduces heat built-up and degradation of material. The cutter
blocks have four corners so they can be easily turned once corner has worn
away.
Different rotor designs available
The ZSS shredder can be equipped with different rotor design. The
flexibility of design facilitates processing of all types of materials. The
rotors can be modified to suit special applications. For example hard facing
of the rotor for abrasive applications. |

| Rotor options |
|
| The ZSS single shaft series is available with
three different rotor choices to tailor the machine to your application. |
|
 |
|
|
|
The ZSS A-rotor choices is very well suited for light materials such as
cardboard, paper, wood as well as food. The rotor features are jagged rotor
design with knife holders welded into place for a very aggressive behaviour. |
|
 |
|
|
The ZSS B-rotor has been especially developed to have a real cut opposed to
traditional shredder rotors as well as minimizing the risk of winding. These
properties make it perfect choice for film and fiber applications.
The rotor has a staggered design, the knifes are bolted into rotor segments.
The design of the rotor makes it less prone to distortion. |
|
|
 |
|
|
|
The ZSS C-rotor is the most versatile rotor available for the ZSS machines,
it can be used for the almost everything from hollow parts to large
materials. The removable knive holders and knifes make it easy to maintain
and service. |
