Operating Instructions Sample Divider Model 8 / Model 32 | Revision 6
1Introduction
1.1 Intendend use
The Sample Divider Model 8 / 32 is used for dividing up samples of grain-like crops (agricultural seed) into
eight or thirty-two sub-samples. The division procedure is used for achieving representative sub-samples.
The Sample Divider is used for the preparation of homogeneous interlaboratory samples. Also for the
preparation of internal control samples needed for regular comparison measurements. The sample is
completely distributed, resulting in no excess amount. Due to the large number of passed openings during
the passage of the sample, the Sample Divider achieves a very good statistical distribution of the different
sample components.
The Sample Divider is designed as a portable machine with a power plug for interiors. The device may not
be used as a production machine or put into continuous operation.
Private use of the machine is prohibited.
NOTICEThe Sample Divider Model 8 / 32 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 Sample Divider is allowed to be operated only if it is ensured that all the safety
devices are functional and the system in which this machine is installed complies with
the EU directives.
The Sample Divider is not suitable for the division of
•flour, dust and grit
•liquid, sticky and oily products
•objects made of metal, stone, concrete, plastic or other foreign components
The samples to be used for the correct operation of the Sample Divider 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.
1.2 Design characteristics of hazard warnings
The Pfeuffer GmbH Operating Instructions contain information which must be observed for the sake of
your personal safety and to avoid damage to property. Information concerning your personal safety is
shown by means of a triangle. Note the following categories of hazard warnings and explanation of
symbols:

There is no provision for adjusting the speed.
7.2 Division of samples
Place one collecting tray under each of the outlet tubes at the intended points.
Switch on the Sample Divider using the ON operating switch.
Pour the sample into the infeed funnel in one movement.
Once the entire sample has run through, set the operating switch to OFF.
Empty the collecting trays.
Repeat the process with a new sample.
When dividing maize, it will be necessary to use an agitator. You can obtain this from
Pfeuffer GmbH, see chapter 11.
NOTICEMake sure that no objects drop into the infeed funnel!
These could damage the Sample Divider when the dividing process starts.

Dividing time
The distributor arm of the Sample Divider turns at a speed of 40 rpm (revolutions per minute) in the
dividing process. This means one rotation takes about 1.5 seconds (s). In each rotation, the eight outlets
are passed over/loaded once.
In order to obtain a representative partial sample, it should consist of at least 40 individual samples. This
means the following minimum dividing time must be observed for the various models:
The Pfeuffer GmbH recommends a dividing time of at least 60 seconds.
The time taken for each product to pass through can be influenced by the funnel outlet. The following
accessories are available for this:
Pass-through time depending on the product
Standard funnel Ø 48 mm
approx. 12 kg/min
Funnel Ø 30 mm:
approx. 8 kg/min
Insert for funnel passage Ø 25 mm
approx. 4 kg/min
Insert for funnel passage Ø 20 mm
approx. 2 kg/min
For the item numbers of the inserts to reduce the outlets on the funnel with Ø 30 mm,
refer to chapter 11.
8Maintenance and cleaning
The chapter maintenance and cleaning is intended for skilled personnel only.
NOTICE Opening the housing and inappropriate operation will invalidate the warranty.
In order to guarantee a failure-free operation of the Sample Divider, it is absolutely necessary that the
machine is regularly cleaned and maintained.
DANGER
Touching live parts can be fatal!
It is essential to comply with the switch-off procedure prior to cleaning, maintenance
or repair work! (see chapter 2.8)
During all work that is required, wear personal protective equipment according to the company
health and safety regulations.
Pay attention to local statutory accident prevention regulations!

8.4 General maintenance instructions
Maintenance is a part of servicing and refers to the scheduled cleaning, checking and replacement of
wearing parts. The aim of maintenance is to maintain the full functionality of the instrument over its
lifetime.
The Sample Divider should therefore be checked for wear and tear at regular intervals. The inspection
intervals depend on the frequency of use and the ambient conditions to which the Sample Divider is
exposed. Only through regular checks (visual inspection) can damage to the instrument caused during use
be detected early and reliably.

A function of all assemblies in setting or manual mode.
