6.5 Taking samples
Depending on the quantity of the ground material, be sure
to use both hands when taking out the grinding stock con‐
tainer. Hazard of tipping!
6.6 Final fineness
The final fineness that can be achieved depends on the selected gap
width (approx. 0.1 mm to approx. 12 mm). The gap width determines
just one dimension of the individual particles in the fine ground material.
For example, material breaking in platelet form may well contain greater
dimensions in one extension direction. Normally however, with this type
of material, the amount of samples with larger dimensions in this exten-
sion direction is also reduced significantly after a second grinding pass.
