Safety instructions – summarised, part 1
We exclude any claims for damages of any kind for injury to persons and damage to equipment arising from non-observance
of the following safety instructions.
Do not make any alterations to the machine and use only spare parts and accessories approved by Retsch. Otherwise the
Declaration of Conformity to the European directives declared by Retsch will lose its validity.
Furthermore this will lead to loss of any kind of guarantee claims.
The rings used could otherwise become damaged.
Please keep the packing material for the duration of the guarantee period, since if you have a complaint and the equipment
is returned in inadequate packing your guarantee claim is at risk.
The RS200 must not be knocked, shaken or thrown during transport. Otherwise the electronic and mechanical components
can be damaged.
If the RS200 is subjected to high temperature variations (e.g. during air transport) it must be protected against condensed
water. Otherwise there may be damage to the electronic components.
If the supplied items are incomplete and/or there is transport damage you must inform the transporter and Retsch GmbH
immediately (within 24 hrs). Later complaints may possibly be no longer considered.
If the temperature drops below or exceeds ambient temperature the electrical and mechanical components can become
damaged and performance data can change to an unknown extent.
At high atmospheric humidity the electrical and mechanical components can become damaged and performance data can
change to an unknown extent.
If the values on the type plate are not observed the electrical and mechanical components can become damaged.
Electrical connection should be carried out only by a qualified electrician. Danger through current surge.
The serial interface cables must not be longer than 2.5 m.
If the cables are longer this can result in disturbances during transmission of data.
Never start the RS200 without the clamped milling set.
Mechanical components can become damaged through high unbalance.
If the values on the type plate are not observed the electrical and mechanical components can become damaged.
The emergency unlocking device must never be operated when the machine is running – only when the machine is at a
standstill and is disconnected from the mains supply.
Danger of injury through unbraked after-running of the drive.
Never start the RS200 without the clamped milling set.
Mechanical components can become damaged through high unbalance.
Please take necessary measures, depending on the dangerous nature of your milling material, in order to avoid danger to
persons.
When removing and opening hot milling cups it is essential to wear protective gloves.
Danger of burning the hands.
Rub the rubber gasket in the clamping plate from time to time with talcum powder and do not leave the milling set in the
RS200 after milling.
Strongly heated milling sets can stick together with the rubber of the clamping plate and are very difficult to remove.
The filling quantity of the milling set must not exceed 1/3 of the nominal volume.
The rings used could otherwise become damaged.
Safety instructions
Use according to the intended purpose
Milling cup nominal volume
The filling quantity of the milling sets must be more than1/3 of the nominal volume.

Safety instructions – summarised, part 2
Before starting the machine ensure that the milling set is clamped.
The milling set can be ejected. Danger of injury and damage to the equipment.
When using easily flammable materials it is essential to observe the section „Wet milling of easily flammable materials”.
Danger of explosion.
If the filling level of the milling set is too high or too low the milling result will be impaired and this can cause damage
(increased abrasion) to the milling set.
Please take necessary measures, depending on the dangerous nature of your milling material, to avoid danger to persons.
When removing and opening hot milling cups it is essential to wear protective gloves.
Danger of burning the hands.
Do not subject milling cups with ceramic inserts to rapidly changing temperature differences when rinsing.
The ceramic units can crack through sudden temperature changes.
Before using easily flammable materials as millling auxiliary agents it is essential to specify in writing the
explosion protection documentation of the EC-directive, according to article 118 and 118a, as laid d own in
directive 89/391/EEC.
Do not clean the RS200 with running water.
Danger to life through current surge.
Use only a cloth moistened with water.
Solvents are not permitted.
Easy running of roller 1 on the closing pin is necessary for reliable closing via the automatic closing mechanism of the RS200.
These operating instructions do not include repair instructions. For your own safety repairs should be carried out only by
Retsch GmbH, an authorised agent or service technicians.

Technical data
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.
The rings used could otherwise become damaged.
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.
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.
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.

Emissions
Noise characteristic values of RS200:
Noise measurement according to DIN 45635-31-01-KL3
The noise characteristic values are influenced mainly by the
machine speed, material to be milled and the milling set.
Workplace-related emission value L
pAeq
= up to 84 dB(A)
Noise power level LWA = 99 dB(A)
Conditions of measurement:
Milling set : 250 ml steel with ring (90/125) and Puk (65)
Milling material : 100g cement clinker, grain size <2mm,
6 milling aid tablets C20
Speed : 1450 min-1
