2.4.4 Weights
2.4.5 Determining the mesh widths
Choosing the correct sieve mesh width is critical for performance and sifting quality.
Choose the mesh widths for the sieve deck according to the following formula:
MW = desired grain size of throughs / 0.8
Select the closest standard mesh width.
Application limit: 2 mm (smallest possible mesh width).
