Retsch 04182-01, 04182-09, 04182-11 Data Sheet

Tech Info

Selection Guide for Retsch® Mixer Jar Mills

Model 04182-01 is mainly used for the
size reduction of small amounts of
sample.

Model 04182-09, with higher energy, can
pulverize samples finer and faster, with
optimum reproducibility. Its convenient
self-locking clamp allows the use of large
jars up to 50 mL.

Table of Guidelines

Grinding jar filling levels—guidelines for sample volume and ball charge. In addition to the instrument settings, the filling level of the
jar is also of crucial importance for the success of the grinding process in mixer mills. A jar filling should consist of about

1

and

⁄3 ball charge. The remaining third is the free jar volume that is necessary for the free movement of the balls. Exceptions to this
are voluminous materials, such as wool, leaves, grasses. In these cases a material filling level of 70 to 80% is necessary. The following
table provides guidelines.
