For a feed size of up to 6 cm as given, Model I will be sufficient. For samples up to 95 mm length, Model II is recommended.
15 minutes of grinding have been necessary to grinding the total sample amount. Model II with a bit wider jaws will need a bit less time compared to Model I.
The ground particles use to be mainly < 6 mm. Some pieces can be found which use to have a maximum length up to 8 mm.
Grinding chamber is almost free of residues. For cleaning, we recommend vacuuming with a soft brush. A grinding of higher amounts is still possible.
