What’s the benefit?
The Twin Roll Shredder (TRS):
- Jaw-like knife design with serrated edges ensures power efficient shredding.
- Is equipped with two torque switches to prevent damage should a hard object (e.g. a tool) accidentally be dropped into it.
- Is bolted together, which makes it easy to inspect for service and maintenance purposes and for replacement of spare parts. Each individual knife can easily be replaced.
- With its low height the TRS is easily fitted into the process line.
- Provides a unique self-cleaning action.
- Has a solid design and very reliable performance.
- Has low maintenance costs and low noise level.

What does it do?
The Twin Roll Shredder (TRS) is designed for shredding of soft and medium-hard materials – dry or slightly wet and semi-sticky. For materials such as wood chips, waste wood, cardboard, plastics, coal, electro-scrap and some metal waste like milling waste.
The Twin Roll Shredder can be used as a primary, secondary or even tertiary crusher.
How does it do it?
The TRS consists of an inlet opening, two counter-rotating roll shafts each with independent gear driven motors and a base frame. The material is by gravity fed through a hopper or duct into the top inlet opening, from where it is drawn into the shredding zone, by the two counter-rotating roll shafts. The twin rolls can be controlled individually or synchronously.
To ensure that the particles exiting the shredding zone are small enough a sieve is placed underneath the roll shafts. If a particle cannot exit through the sieve, it is forced back into the inlet of the counter-rotating rollers for further shredding.
The design ensures a unique self-cleaning action.
