Fast and powerful grinding for unlimited applications
RETSCH ball mills are appropriate for a large vary of applications. Depending
on the model (planetary ball mill or mixer mill), they’ll be used for dry, wet
or cryogenic grinding. Mixing, homogenizing, cell disruption, mechanical
alloying and even colloidal grinding are any doable applications. Due to
their versatility they’ll be utilized in just about all sectors involved with the
mechanical treatment of solids in business and analysis.
Grinding jar attachment-easy and saf
The distinctive grinding jar attachment system of the MM four hundred permits fast,simple and safe clamping of the jars.
The automatic centering and precise placement of the grinding jars optimizes the reproducibility of the
grinding method. The self-locking device prevents the grinding jars from changing into loose throughout the
Cryogenic grinding-fast and economical
The Mixer Mill MM four hundred is ideally appropriate for cryogenic grinding.Sample material and grinding ball charge are placed within the screw-top
stainless steel grinding jars, that are then immersed in liquid nitrogen.After having cooled down sufficiently,
they are mounted within the quick-clamping device of the MM 400; this is the
grinding jars securely, even at very low temperatures.After a grinding time of solely a pair of – three minutes a very
homogenized sample is obtained.This procedure saves time and isparticularly economical attributable to the terribly low consumption of liquid nitrogen.
Controlled forces in single-station planetary ball mill
Planetary mills with one grinding station need a counterweight
for balancing functions. within the Ball Mill PM one hundred this counterweight are often
adjusted on an inclined guide rail. during this approach the various heights of the
centers of gravity of differently-sized grinding jars are often compensated in
order to avoid disturbing oscillations of the machine.
Any remaining vibrations are compensated by feet with some free movement
(Free-Force Compensation Sockets). This innovative FFCS technology is
based on the d’Alembert principle and permits terribly little circular movements of
the machine housing that lead to an automatic mass compensation. The
laboratory bench is simply subjected to minimal frictional forces generated in
In this approach the PM one hundred ensures
a quiet and safe operation with most compensation of vibrations even with the most important
pulverization forces within the grinding jars and so are often left on the bench unsupervised.
