Intended use
Use:
The A 11 basic analysis mill is a batch mill that allows for two different grinding
procedures.
The grinding container is airtight. This means that the loss of ground material is
equivalent to practically zero.
Impact milling:
For usage with hard, brittle grinding material, dried material or material that is brittle
because of cold (for example grain, coffee, etc.).
Here the grinding material is reduced by means of a beating rotor. The grinding mate-
rial is thus broken. The granularity of the final product is determined by the duration
of the grinding, the level to which the container is filled and the physical properties
of the material being processed.
Cutting milling:
For usage with soft, fibrous grinding material (for example hay, paper, etc.).
Here the grinding material is cut by means of a rotating blade. In this case as well,
the granularity of the final product is determined by the duration of the grinding, the
level to which the container is filled and the physical properties of the material being
processed. Using the cutting method makes it possible to introduce less energy into
the grinding material, which results in less heating up. In this case as well, because of
the closed design, the loss of ground material is equivalent to practically zero.
Range of use:
Indoor environments similar to that a laboratory of research, teaching, trade or
industry.
The safety of the user cannot be guaranteed:
› if the device is operated with accessories that are not supplied or recommended by
the manufacturer.
› if the device is operated improperly or contrary to the manufacture’s specifications.
› if the device or the printed circuit board are modified by third parties.
Power supply / switching off the device:
› The voltage stated on the type plate must correspond to the power voltage.
› The device can only be disconnected from the power supply by pulling out the pow-
er plug or the connector plug.
› The socket for the power cord must be easily accessible.
Disposal instructions:
› The device, accessories and packaging must be disposed of in accordance with
local and national regulations.
Maintenance:
CAUTION
› The device must only be opened by trained specialists, even during repair. The de-
vice must be unplugged from the power supply before opening. Live parts inside
the device may still be live for some time after unplugging from the power supply.
› Beware of the sharp edged cutter in particular when changing grinding tool and when
cleaning. Always wear your personal protective equipment (protective gloves, etc.).
› The grinding pot, grinding tool and rotor shaft may be hot after long grinding cy-
cles. Allow the mill to cool down before cleaning or before changing grinding tool.
› Before removing the grinding beaker, switch off the mill and wait until the motor
stops. Risk posed by trailing crushing elements (beaters or cutters).
› Always switch off the device and disconnect the plug before cleaning or replac-
ing parts.
