General
The MM 200 is an ultramodern, high performance product
from Retsch GmbH.
Owing to the large selection of accessories the laboratory
oscillation mill, type MM 200, is a machine with many
different application possibilities, mainly in the chemical and
pharmaceutical sectors, in mineralogical and biological
applications etc, as well as in industrial laboratories and in
research.
The milling process
Clamp the machine filled with material to be milled, together with
the milling ball(s) in the milling cup holder as described.
Close the hood.
Set the milling parameters.
Start the MM 200.
Do not open the hood during the milling process.
Although the milling cups are brought to a standstill immediately
by the built-in brake, the milling process can no longer be
continued with the remaining running time.
The MM 200 must be restarted and the initial parameters are then
again available.
In order to guarantee quiet running of the MM 200 we recommend
that milling cups with the same mass as far as possible are
clamped in both milling positions.
Do not open the plexiglass hood during the milling process.
Although the milling cups are brought to a standstill immediately
by the built-in brake, the milling process can no longer be
continued with the remaining running time.
The MM 200 must be restarted and the initial parameters are then
again available.
