6 Using the device
6.1 Conducting a grinding operation
6.1.1 Parameters
Grinding duration 10 ... 30 min (average)
Amplitude 1 ... 2 mm (max.)
Feed quantity Max. 10 ml (particle feed size ≤ 5
mm)
6.1.2 Fitting and clamping the mortar
1. Move the clamping lever on the belt clamping device downwards
and insert the toothed belt through the holder from the inside to
the outside.
2. Place the mortar and the ball on the vibratory plate. The mortar
must be positioned in the round gap of the vibratory plate without
being wedged.
3. Unscrew the knurled knob on the toothed belt as far as possible.
4. Pour in the grinding stock.
5. Put on the clamping lid.
6. Attach the knurled knob to the lid
7. Lightly pull the toothed belt tight and move it upwards until its
teeth interlock with the teeth of the belt clamping device.
8. Move the clamping lever upwards.
Make sure that the teeth of the toothed belt interlock
with the teeth of the belt clamping device!
9. By turning the knurled knobs to the right, tighten the mortar
evenly until the toothed belts are tightly clamped!
If the two toothed belts are not evenly clamped, it is
possible that the grinding stock will escape from the
mortar.
Select an amplitude for grinding at which the ball vibrates. The best
grinding results can be achieved at a medium amplitude (1 mm to max. 2
mm), as the impact frequency of the grinding ball is then highest.
