Infeed hopper

The machine is equipped with a large, central infeed hopper. In addition to standard solutions, customer-specific hoppers are also available.

Machine housing

The machine housing is designed as a highly robust, one-piece, welded steel construction. This allows the machine to absorb extremely high forces without difficulty.

Rotor with shearing tools

The material is shredded between two rotor shafts rotating in opposite directions towards the center. The shearing tools are specially positioned on the rotor shafts to ensure a high crushing performance.

Scrapers

The scrapers are attached to the side walls of the machine housing and reach in between the shearing discs. They prevent material from adhering to and building up on the rotating shear discs. If discs wear out, each one can be replaced individually. Every shaft is powered independently. The drive consists of a spur gear and an electric motor from well-known manufacturers. In case of an overload, the drive allows the shearing disc to be retracted by changing the direction of rotation.

Torque buffering

 As a standard feature, each drive unit is protected by large torque buffers. Every buffer unit consists of four solid rubber elements mounted to a robust welded steel structure.

Hydraulic Pusher Unit

A hydraulic pusher device is available as an option. It ensures continuous material infeed when processing low-density, light or bulky feed stock.

Frequency Inverter

The machine can optionally be equipped with an electronic frequency inverter. This allows the speed to be adapted to individual process conditions and prevents the generation of costly peak currents.

The shear shafts’ quick-change system consists of a specially designed quick coupling located between the shear shaft and the gearbox and a patented bearing shell bridge. The quick coupling is screw-fastened and makes shaft changing possible without having to disassemble the drive system. The bearing shell bridge can be easily removed. Once this is done, it is then possible to remove the shear shafts by lifting them up.

Two rotor shafts, which rotate in opposite directions towards the center and collect the input material, are enclosed in a heavy-duty housing. Each shaft is equipped with several high-precision cutting tools that function like scissors. There are gripping hooks at the tip of each tool that ensure fast and reliable material infeed. The hydraulic pressure unit can be used to assist as needed in individual cases. Scrapers are placed on the outside of the shaft to prevent material from sticking to the rotating cutting tools. The particle size of the end product greatly depends on the width of the selected cutting blade.
