design principle of the LRK machin e is almost identical to the LR machine, however the
main frame had been essentially reinforced for industrial applications. It was obvious
from the beginning on that they LRK machines will be used in many different fields,
therefore two different cuttin gsystems had been developed.
To increase the efficiency on a single shaft shredder makes it necessary to adapt the cutting system to the input material. This is similar to the 4 shaft shredder where different cutting blades are available to meet the requirements.
Most of the other single shaft shredder manufacturers have only one system available with some minor variations in number and size of the cutters. Our new concept consists of two different cutting systems to gain significant higher capacities at most of the materials.
|System: USS Rotor|
|Milling action of the rotor, each revolution creates overlapping and consequently some advance. Inclinded to improve the material flow with less power efforts. With all 4 edges flattened, moving in a circular motion along with inner suface of the screen to increase the wear resisitance and the efficiency. Other manufacturers: sharp edges with just one line moving along the screen surface|
|System: SKS Rotor|
|The goal was to develope a rotor special design to prevent winding of material around the rotor (especially foils). The new chamber rotor with the adjacent chamger bars clears the material off from the rotor. Carpet and big bag grinding where our competitors still have significant problems is now possible. The output material is of uniform size due to the precise cutting sequence in the chamber, the material escapes easily through the screen holes.|
|Rotor Cooling System|
of the rotor is necessary when following materials are continoulsy grinded.
- PVC soft melting point < 80 degrees Celcius
For following materials rotor cooling is not required
- Plastic lumbs
High rotor temperature will cause thermal expansion of the rotor. The gap between the cutting knives and cutting bars will be therefore consequently altered.
Why have not all of the 1 shaft shredder manufacturers
implemented rotor-cooling systems?
