Retsch AS 200 - Technical Data; Degree of Protection; Emissions and Noise Levels

Technical Data
11
3 Technical Data
3.1 Degree of Protection
 IP54 (IP20 in the area of the sieve carrier passage)
3.2 Emissions
CAUTION
C4.0011
Possibility of acoustic signals not being heard
Loud sieving noises
 Possible acoustic alarms and voice communication might not be heard.
• Consider the volume of the sieving noise in relation to other acoustic
signals in the work environment. Additional visual signals may be
used.
CAUTION
C5.0017
Hearing damage
A high sound level may be generated depending on the type of material, the
number of sieves, the sieving aid used, the amplitude set and the duration of the
sieving
 Excessive noise in terms of level and duration can cause impairments or
permanent damage to hearing.
• Ensure suitable noise protection measures are taken or wear ear
protection.
Sound parameters:
The sound parameters are also influenced by the set amplitude, the number of test sieves and
the properties of the sample material.
Example 1:
Number of test sieves:
5
Amplitude:
1.5 mm
Feed material:
Quartz sand (< 1 mm)
Sieve clamping unit:
"comfort"
At these operating conditions, the workplace related equivalent continuous sound level
L
eq
= 51.2 dB(A).
Example 2:
Number of test sieves:
5
Amplitude:
3 mm
Feed material:
Quartz sand (< 1 mm)
Sieve clamping unit:
"comfort"
At these operating conditions, the workplace related equivalent continuous sound level
L
eq
= 61.6 dB(A).
