2 Distribution auger
2.1 Height adjustment
Depending on the material, the height of
the distribution auger (1) – measured
from its lower edge – should be at least
50 mm (2 inches) above the height of
the material layer.
Example: Layer height 10 cm
Adjustment: 15 cm from
the ground
An incorrect height adjustment can re-
sult in the following problems:
- Auger too high:
Too much material in front of the screed; material overflow. When operating with
larger widths, demixing and traction problems may occur.
- Auger too low:
Not enough material that can be precompacted by the auger. Irregularities resulting
from this cannot be completely compensated for by the screed (wavy surface).
In addition, increased auger segment wear occurs.
