Wear or damage to the grinding set
No filling or insufficient filling quantity
– Increased wear or damage to the grinding set is possible if the grinding set
is operated without filling or with insufficient filling qantity.
• The grinding set must be filled to at least 1/3 of the nominal volume.
4.3 Feed Grain Size
In addition to the instrument settings, the filling level of the grinding jar is also of crucial
importance for a successful grinding process in the Vibratory Disc Mill of Retsch GmbH. The
table indicates approximate values for the recommended amount of sample as a function of the
grinding set used. A median filling (sample quantity) results in best grinding efficiency and
increases the life time of the grinding sets.
