Single shaft shredder
Single-shaft shredders are granulators with only one knife shaft.
They are used in the wood industry for processing wood waste and conditioning it into fuel . They have been adapted to other tasks in recent years and are also used to process plastic residues, substitute fuels, paper, nonwovens or electronic scrap.
Single-shaft shredders consist of a rotor which is provided with knife seats for holding rotor knives. These are usually reversible and interchangeable several times. The knife shaft works against a fixed knife block (stator).
Compared to other cutting mills with closed rotors and segmented knives, the single-shaft shredders cut with a lower peripheral speed and a large number of small cutting surfaces on the rotor and on the stator.
With good chip evacuation, the exact cut enables a low thermal load on the material to be shredded and a homogeneous grain size (depending on the machine from a few mm to a few 10 mm) with a low level of dust due to the process.
The shredding result depends on the size and arrangement of the blades, the shape of the blades and the rotor speed.
Parameters of large machines are, for example, a filling opening of about 2 × 2 m, a drive power of 75 kW and a knife shaft diameter of about 0.5 m at 80 / min:
