Technical specifications
Machine type designation: PM100/PM200
Intended use
Retsch ball mills are used to grind and mix materials that are soft,
medium hard to extremely hard, brittle or fibrous. Dry and wet
grinding is possible, grinding with solvents is permissible, although
in this case it is essential to observe the supplementary instructions
given in the chapter "Wet grinding with easily inflammable
materials". Minerals, ores, alloys, chemicals, glass, ceramics,
vegetable matter, soil, slurry, domestic and industrial waste
and many other substances can be comminuted simply, quickly
and without loss. The ball mills are successfully deployed in
virtually all fields of industry and research, particularly where
there are high requirements on cleanliness, speed, fineness and
reproducibility.
Only type "C" grinding bowls may be used.
In the PM100 1x of 50-500ml, 2x50ml, 2x25ml and 2x12ml can be
stacked.
In the PM200 the 12ml and 25ml grinding bowls can be stacked but
the 50ml and 125ml are not stackable.
They are not designed as production machines, but rather as
laboratory devices intended for single-shift, 8-hour operation.
Do not make any modifications to the machine and only use
Retsch approved spares and accessories.
The conformity to the European guidelines declared by
Retsch will otherwise lose its validity.
It will furthermore lead to the loss of all warranty claims.
Maximum feed volume
PM100 = up to 300ml, depending on the grinding bowl volume.
PM200 = up to 2x50ml, depending on the grinding bowl volume.
Maximum feed grain size
PM100 up to <10 mm, but dependent on the material
PM200 up to <4 mm, but dependent on the material
Drive output
750 W / power draw approx. 1250 W
Emissions
Noise levels PM100:
Noise measured in accordance with DIN 45635-31-01-KL3
The noise levels are basically influenced by the speed of the
machine, the size of the grinding bowl and the diameter of
the grinding balls used.
Workplace related emission value L
pAeq
= up to 85 dB(A)
