Technical data Target group: Operating authority, operator Machine type designation: MM 200 Use according to the intended purpose This machine is not designed as a production machine. It is a laboratory machine intended for 8 hour single-shift operation with a 30% on-period. The MM 200 is suitable for milling and homogenising soft, fibrous, hard and brittle materials in the wet and dry state. The MM 200 is designed for very small quantities of approx. 0.5 to 8 ml.
Protective equipment The milling chamber of the laboratory mill MM 200 is enclosed by a strong covering hood. Starting the machine is possible only with the hood closed. Emissions Noise characteristic values : The noise characteristic values are also influenced by the properties of the material to be milled. Example 1: Intensity of sound LWA = 71.
Protective systems IP30 Rated power: 100 Watt Machine dimensions Height: Width: Depth: 266 mm up to approx. 524 mm with hood opened 371 mm 461 mm Weight: approx. 26 kg without milling cups Required floor space 400 mm x 500 mm; no safety distance required.
Transport and installation Target group: operating authority, transporter, operators Packing Packing is adapted to the transport route and conforms to generally applicable packaging guidelines. Please keep the packing material for the duration of the guarantee period since if there is a complaint and the machine is returned with inadequate packing your guarantee claim will be at risk. Transport The MM 200 must not be knocked, shaken or thrown during transport.
Conditions for the place of installation Ambient temperature: 5°C to 40°C If the ambient temperature drops below or exceeds these values the electronic and mechanical components can become damaged and performance data are changed to an unknown extent. Atmospheric humidity: Maximum relative humidity 80% at temperatures up to 31°C, decreasing linearly down to 50% relative humidity at 40°C.
Electrical connection The voltage and frequency for the MM 200 are given on the type plate. Ensure that these values correspond to the available power supply system. Connect the MM 200 to the power supply system using the supplied connection cable. Protection by external fusing is to be used when connecting the mains cable to the power supply, according to the regulations at the place of installation. The voltage supply of the MM 200 must be fitted with a fault-current circuit breaker (FI switch).

PROG Calls the stored programmes SET Stores the set milling parameters Frequency display The frequency can be set continuously from 03.0 to 25.0 Hz here. Frequency – minus button In the on mode and in the operating mode: Reduction of the set frequency by 0.1 oscillations per second.
Inserting / replacing the milling cups Place the milling cup filled with the material to be milled and the milling balls between the rubber supports GA of the clamping device and clamp the cups firmly. Fig.1/2 HD First turn the adjusting nut SM as far as possible counterclockwise so that the cup can be clamped afterwards. Then turn the handwheel HD clockwise until the milling cup is firmly clamped. Turn the adjusting nut SM clockwise in order to secure the handwheel against becoming loose.
Setting the milling time • Switch on the MM 200 with switch D Preselect time: • Set required milling time with + / - buttons N+ and Neinstellen. • Short pressing of N+ or N– adjusts the time by one second or one minute. When pressed for longer the display runs continuously without a pause. N- N+ If 99.0 minutes is exceeded the display L shows 0.10 seconds again. Setting the frequency Preselect frequency: • Set the frequency with + / - buttons M+ and M-.

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.
Milling of materials which can cause a fire or explosion in the MM 200 is prohibited. Please take any necessary measures to prevent danger to persons, depending on the dangerous nature of your sample. Please note that the properties, and therefore the dangerous nature of your sample, can change during the milling process. Safety instructions for handling liquid nitrogen When handling liquid nitrogen always wear protective goggles and protective gloves.
Safety functions and fault displays Safety functions F01 F01 - Overloading In order to avoid overloading of the drive motor and resulting endangerment to the user the MM 200 is fitted with a load monitoring device. In case of overloading the monitoring function switches the machine off in good time. At the end of the cooling time it is only necessary to switch the machine off and on again in order to be able to operate it normally again.
Cleaning Do not clean the MM 200 with running water. Danger to life through current surge Use only a cloth moistened with water.
