The perfect conditions
All applications are different, but the goal is the same: we want to ensure that your shredder adds value to your operation. A WEIMA shredder makes it easier to transport, clean, sort, and/or reuse materials.

When it comes to scrap: Intelligent shredding turns waste into a resource.
The shredding process with ram, rotor, screen and material discharge

For decades we’ve been using shredding solutions to make “everything smaller.” With our wide spectrum of machine types, we are in a position to shred materials like plastic, paper, wood, cardboard, biomass, waste and secure documents.

Select your preferred drive type
Electromechanical drive
In most cases, single-shaft shredders are equipped with an electromechanical drive. The power is transmitted by means of a norm motor, the specially developed WEIMA WAP gear and a power belt. The speed is adjustable.

High-torque drive
The high-torque, multi-pole synchronous motor from Baumüller is produced in Germany and is characterized by its insensitivity to foreign objects. Without gears, the drive resists shocks and vibrations and thus has a particularly long service life – even when shredding challenging material streams.

Hydraulic drive
Hydraulic drives from Hägglunds / Bosch Rexroth have no gearbox and are therefore particularly insensitive to many impurities. Speed and torque can be adjusted without current peaks. The robust drive provides high torque at low kW power. The speed can be variably adjusted by means of a regulating pump.
Rotor and cutting technology: The optimum coordination of rotor, knives and counter knives is crucial for the shredding result. The selection of the components suitable for the material requires a high degree of experience.
No two applications are the same. But one thing remains: The rotor is the heart of a shredder. It is fitted with cutting knives and rotates between 30 and 400 revolutions per minute, depending on the material and machine.
Cutting knives come in many different sizes and shapes. They are either welded or screwed onto the rotor. Especially important: the exact adjustment of the cutting gap between the cutting knives and counter knives. This is where the actual shredding takes place – comparable to a (very large) pair of scissors.

Screens for material discharge
The screen fixed around the rotor defines the material size (grain size) to be achieved. As a rule, the larger the holes, the coarser the shredded material. WEIMA offers the following screen designs: Round hole, honeycomb, kidney, zig-zag.

Full speed ahead
For a rotor to turn, it must be driven by a power source. There are several possibilities for this. While a 170 kg rotor must be set in motion in a WL 4 shredder, a PreCut cutting shaft weighs a massive 7 tons. A real challenge for mechanics and electronics. In general, we distinguish between three types of drive: electromechanical, hydraulic and high-torque.
Did you know?
Enormous forces act on shredder gears. That's why WEIMA builds its robust WAP transmissions in Germany itself and doesn't buy in. This guarantees a long service life.

What use is a razor-sharp rotor and many kW of drive power if the material to be shredded does not reach it at all?
That is what the ram is for. Whether horizontal or swung – a perfectly adjusted ram significantly increases throughput.
Horizontal ram
By means of hydraulic pressure, the ram moves horizontally forwards and backwards. The movements can be controlled automatically, in cycles or manually. If required, this is done load-dependent. It is precisely guided by brass guide rails so that it does not jam. A shock valve at the rear end of the ram also absorbs shocks, making the system even more robust.

Wing ram
The material feed by means of swing technology makes the shredder particularly compact, simplifies maintenance and allows a more aggressive material feed. As an option, the swing ram can be equipped with an attachment, which further improves the feeding process.
"We must shred waste –
or our world will overflow."
Peter Rössler, company founder and visionary entrepreneur
Heavy duty machine design
WEIMA shredders for processing highly abrasive materials can be protected with various options to reduce wear and thus downtime and maintenance costs. The heavy wall thickness of the machine frame makes WEIMA shredders particularly robust. The rotor can be reinforced with Vautid, the screen with Creusabro. To protect the cutting knives against the impact of foreign objects, large knives with edge lengths of up to 130 mm x 130 mm can be selected. If the number of knives is small. Vautid can also protect knife holders.
Vautid weld-on for shredder rotor
To avoid increased wear of the rotor face plates, we recommend the installation of replaceable Creusabro wear plates on both sides. The cutting chamber can also be reinforced and optionally lined with exchangeable Creusabro plates. Wear protection does not stop at the screen, which defines the material size. For particularly high wear, we offer a screen reinforced with Creusabro with a wall thickness of approx. 20 mm.
Main shredder components in detail
Maximum ruggedness and high precision at the same time – everyday, WEIMA shredders all over the world prove that this is possible. The interaction between rotor, cutting knives, ram, screen and, of course, the best-fitting drive, define the individual cutting solution. You can count on the experience of several tens of thousands machines in the market and world-famous Swabian engineering for over four decades.
