1Introduction
Intendend use1.1
The laboratory mill MILOMAT is used to mill agricultural cereals. The impact mill is perfect for pre-
crushing and fine crushing from soft to medium-hard products. Even dry and tough samples can be
milled without difficulties.
The milling material is used for the moisture determination with the Pfeuffer moisture meter HE 60 and
HE 90.
The outlet nozzle of the MILOMAT is therefore adapted to the measuring cells of these two moisture
meters. The MILOMAT should only be operated with a measuring cell under the outlet nozzle. During
the milling process, strong air flows and heating are avoided in order not to influence the actual
moisture content. The MILOMAT is therefore used for the sample preparation and to be seen as
accessory for the moisture meter.
The MILOMAT is designed as a portable machine with a power plug for interiors. The laboratory mill
may not be used as a production machine or put into continuous operation.
Private use of the MILOMAT laboratory mill is prohibited.
NOTE The MILOMAT laboratory mill was designed solely for the aforementioned purpose.
Using it for any other purpose or
modifying it without the written consent of the
Pfeuffer GmbH is not considered to be in compliance with the intended use.
The Pfeuffer GmbH shall not be liable for the resulting damage. Damage caused by
such an unintended use is at the sole risk of the operator.
The MILOMAT
is allowed to be operated only if it is ensured that all the safety
devices are functional.
The MILOMAT may not be used for milling material containing solid and massive
objects made of metal, stone, concrete, plastic or other foreign components.
The MILOMAT is not suitable for liquid and sticky products.
The samples to be used for the correct operation of the MILOMAT are provided by
the operator.
The operator bears sole responsibility for the proper handling of these materials and
the associated dangers.
Hazard notes and instructions for disposal must be provided by the operator.
Intended use includes also the compliance with the Instruction Manual and User´s Guide as well as the
maintenance and servicing conditions, as specified in these Operating Instructions.
These Operating Instructions do not relieve the operating company of the obligation to develop and to
apply independent health and/or safety regulations or safe working processes which are aimed at the
requirements of the overall machine, as well as the obligation to monitor their compliance.

The laboratory mill MILOMAT is an impact mill for agricultural cereals. Fill a measuring beaker (0.02 l,
accessory moisture meter HE 60/90) with the cleaned sample. Place the contents in the filling hopper.
The product trickles into the milling chamber by rotating the dosing knob. The product is smashed
between a standing and a rotating metal pin collar (impact effect). The milling material falls into the
bottom part of the measuring cell of the moisture meter HE 60/90 via the outlet nozzle.
For precise information about operation, refer to chapter 7.
For detailed information on the product quantity and the measuring method, please refer
to the respective Operating Instructions of the moisture meter HE 60/90.

Milling process of inhomogeneous milling material with a sample dividing cup (option)7.3
The sample dividing cup is used to increase the measuring accuracy by using a larger sample quantity.
We recommend the use of the sample dividing cup especially for sample preparation for the moisture
determination of humid maize.
For products where a moisture balance has already taken place (through storage), there is no
improvement for the measurement result.
Figure 13: Sample dividing cup
Instead of one measuring beaker, mill for maize two
measuring beaker (2 x 0.02 l) of the sample.
Then divide the sample halfway through the sample
dividing cup.
This results in an average pattern.
Pull out the separating sheet completely.
Place instead of the bottom part of the measuring
cell the sample dividing cup under the outlet of the
MILOMAT.
Push the outlet nozzle downwards.
Carry out
the milling process with two filled
measuring beaker, as described in chapter 7.2.
Push the outlet nozzle upwards after the milling
process has finished.
Figure 14: Place the sample dividing cup under outlet
Remove the sample dividing cup.
Mix the sample thoroughly with the stirring rod.
Straighten the sample surface by gently shaking.
Insert the separating sheet into
the guide of the
sample dividing cup. This divides the sample into
two equally sized halves.
Then fill in the sample into the bottom part of the
measuring cell and carry out a measurement in
