1.V0043
Damage to hearing
A greater sound level may occur depending on the type of material,
the sieve column and the set oscillation amplitude or sieve base
acceleration.
–
Excessive noise in terms of volume and duration can cause
impairments or permanent damage to hearing.
• Ensure there are suitable soundproofing measures or wear
hearing protection.

Noise characteristics:
The noise is measured in conformance to DIN 45635-031-01-KL3.
The noise characteristics depend on the set amplitude or sieve base acceleration,
the number of sieves mounted and the type of material being sieved.
Example 1):
Operating conditions:
Sieved material = quartz sand, grain size <1mm, 5 sieves
Amplitude = 1.1 mm
Sound-power/noise level = 69 dB (A)
Example 2):
Operating conditions:
Screening = quartz sand, grain size <1 mm, 5 sieves
Amplitude = 2.2 mm
Sound-power/noise level = 79 dB (A)
CAUTION
Damage to hearing
The level of noise can be high depending on the type of material, the
sieve stack used and the set amplitude and/or sieve base acceleration.
- Noise that is excessive in terms of level and duration can cause
impairments or permanent damage to hearing.
• Provide suitable sound proofing measures or wear hearing
protection.
