X = 39.75 mm opening width
The accuracyof this calculation depends on the maximum particle size. The finer
the feed quantity, the more precise the calculation.
Determine the minimum opening width.
The minimum opening width must correspond to at least three times the maximum
particle size .
Example :
Particle size = 8 mm
Minimum opening width= 3 x 8 = 24 mm
Formula:
X
min
= 3 x d
max
If the opening width is narrower, a distortion of the sub-sample can be expected.
5.15.2 Determining the minimum opening width
The minimum opening width must correspond to at least three times the maximum
particle size.
Example :
Particle size = 8 mm
Minimum opening width= 3 x 8 = 24 mm
Formula:
X
min
= 3 x d
max
If the opening width is narrower, a distortion of the sub-sample can be expected in
this case.
