- 40 -
Using the device
The quantity of comminution material is based on the particle feed size and the grindability of the material. It is best to start with small quantities and increase them depending on the success of the comminution.
NOTICE!
When the sample bottle (32) is 2/3 full, stop the comminution. To do this, switch off the cutting mill (see
Ä Chapter 5.4 ‘Switching off’ on page 26) and the sample
exhaust system. Then empty the sample bottle (32).
If comminution has not stopped when the bottle is 2/3 full, the effectiveness of the classifier is impaired and material will gradually clog the filter of the sample exhaust system.
If the vortex of comminution material in the collection bottle slows down, this means that the air throughput or air flow rate has decreased: n grinding chamber is too full n the sieve has to be cleaned and / or n the filter of the exhaust system has to be cleaned.
NOTICE!
The fine material (fine dust) of the sample collects in the filter of the sample exhaust system. Clean the filter from time to time by vacuuming or blowing out.
The sample exhaust system is recommended especially in combination with the standard funnel (1) for bulk and long solids.
