•Push the handle of the door latch (F) backwards.
•Open the grinding chamber door (T).
•Pull the plunger (B) into the upper latching position.
•Place the feed hopper (R) on the device. (see diagram)
CAUTION
Until the feed hopper (R) is secured by two socket-head screws, there is a risk of it falling out of
the device.
•Release the detent pin bolt (D) on the plunger (B).
•Push the plunger downwards.
•Screw the two provided socket-head screws (S) through the hinge on the
feed hopper into the enclosure.
•At first, tighten the screws only slightly.
•Close the grinding chamber door.
•Pull the handle on the door latch (F) forwards until the mini detent pin (E)
engages.
•Adjust the feed hopper until the plunger can be moved upwards and
downwards easily without jamming.
•Tighten the two socket-head screws securely. (10 Nm)

4 Technical Data
4.1 Use of the Device for the Intended Purpose
Target group: Owners/managing operators, operators
Machine type designation: SM 200
This heavy-duty cutting mill serves to grind flexible, hard-ductile and fibrous products and
product mixtures in batches or continuously. It is fundamentally not designed for grinding wet or
moist materials. The special shape of the cutting tools in conjunction with the drive enables a
fast, efficient grinding without adversely affecting the material to be ground.
Special features
The new heavy-duty cutting mill is convincing in difficult size reduction tasks where other cutting
mills fail. The device allows a particularly effective preliminary size reduction of heterogeneous
material mixes, such as waste or electronic components. Analytical fineness is usually attained
in one step. The cutting mill is used successfully for a great variety of other materials also,
whereby the sample material is only heated to a very low temperature and so the mill is also
suitable for grinding temperature-sensitive materials.
The large selection of sieves, hoppers and collecting vessels allow adaptations to individual tasks.
- fast, gradual size reduction by 18 cutting plates arranged in a helical pattern
along the circumference of the rotor
- parallel section rotor
- cutting tools made of high-quality materials
- high level of operating convenience due to central lock and operator panel
- consistent operational reliability in all user-relevant equipment components
- versatility in use due to a variety of devices and a large number of
accessories
- powerful size reduction owing to a high-torque 2.2-KW motor
- optimised cutting effect by double-acting cutting bars
- very fast cleaning thanks to hinged enclosure with smooth surfaces and
push-fit rotor
- defined final fineness due to bottom sieves with aperture sizes 0.25 - 20 mm
NOTICE
Area of use of the machine
–This machine is a laboratory machine designed for 8-hour single-shift
operation.
•This machine may not be used as a production machine nor is it
intended for continuous operation.

4.2 Emissions
CAUTION
Damage to hearing
The level of noise can be high depending on the type of material,
the knife used, the speed set and the duration of the grinding
process.
- Noise that is excessive in terms of level and duration can cause
impaired or permanently damaged hearing.
•Ensure suitable sound-proofing measures or wear
hearing protection.
Noise measurementin accordance with DIN 45635-31-01-KL3.
Immission at 1-m spacing:
- approx. 66 dB (A) at idle speed
During size reduction, depending on the sample material:
- approx. 75 to 92 dB (A) with peaks of up to 98 dB
4.3 Degree of Protection
–IP54
4.4 Motor rotation speed
The rated speed of the motoris 1500 rpm.
4.5 Receptacle Volume
The receptacle volumeis < 5 l and is expandable by accessories to up to 26 l.
