Technical data
Machine type designation: RS200
Use according to the intended purpose
Retsch vibratory disc mills are used for rapid, loss-free, fine milling
of medium-hard, hard/brittle and hard/tough materials. Both dry
and wet milling operations can be carried out. Milling with solvents
is permitted. In this case, however, the supplementary notes in the
section „Wet milling with easily flammable materials“ must be
observed.
Soil samples, ores, coal, coke, corundum, metal oxides,
minerals, plant samples, slags, silicates, cement and many
other substances can be milled, easily, quickly and without loss.
These oscillating disc mills are used successfully in practically all
areas of industry and research, particularly where stringent
requirements are set on purity, quickness, fineness and
reproducibility.
They are not designed as production machines, but as laboratory
equipment, intended for 8-hour single shift operation.
Do not make any alterations to the machine and use only spare
parts and accessories approved by Retsch.
Otherwise the Declaration of Conformity with the European
directives declared by Retsch loses its validity. Furthermore this
will result in the loss of any kind of guarantee claims.
Milling cup – nominal volume
Special steel: 50 / 100 / 250 ml
Agate: 50 / 100 ml
Tungsten carbide: 50 / 100 ml
The filling quantity of the milling sets must be more than 1/3 of
the nominal volume.
The rings used could otherwise become damaged.
Maximum charged grain size
The maximum charged grain size depends on the milling cup
volume and the degree of hardness of the milling material.
Milling set 50 ml = max. grain size < 5mm
Milling set 100 ml = max. grain size <10mm
Milling set 250 ml = max. grain size <15mm
Driving power
1500 W
Motor speed
The speed is adjustable in the following range:
 700 - 1500 min -1
For agate sets adjustment of a speed greater than 700 min -1 is not
possible.
If no milling set is clamped in position the speed is also limited to
700 min
-1 .
