Wet Grinding (Grinding in Suspension)
When grinding in suspension, you can add auxiliary substances in liquid
form with a high boiling point and low vapour pressure.
Flammable liquids with a boiling point <100°C should not be used.
4.4 Clamping the Grinding Bowls
The following tests should be performed before the grinding bowls are clamped
in the machine:
Check the cork disc for damage.
Replace cork discs that are black and flattened.
The flat Teflon seal (for sealing between the lid and the bowl) must
not be damaged or dirty.
Replace severely deformed flat Teflon seals.
Check the rubber disc for damage.
Replace rubber discs that are flattened and project laterally beyond
the pressure piece.
The plane surfaces of the counter plate and of the clamp clip must
not be dirty.
The surfaces of the lid and of the bowl on which the flat Teflon seal
rests must be clean.
Clamping
Place the sealing ring and the lid on the bowl.
Insert the grinding bowl in the pot mounting on the cork disc. Do not tilt it.
Screw the spindle down fully until the rubber disc of the pressure piece rests
flat on the lid.
Tighten the spindle by hand.
Screw the counter plate down fully until it rests flat on the clamp clip.
Tighten the counter plate by hand.
After a few minutes of grinding, and in the cooling phases, check that the
spindle and the counter plate are secure.
