SAMPLE DIVIDING
RT 6.5 – RT 75 SAMPLE SPLITTERS
SAMPLE DIVIDING
RETSCH sample splitters are used for the simple
dividing and reduction of bulk materials of all
kinds.
Sample Splitters are ideal for the on-site reduction of sample material. They are easy to use,
easy to clean and do not need an electrical
power supply.
In every dividing operation, the feed material is
halved. This process can be repeated as many
times as necessary, as a function of grain size,
until the quantity needed for transport or
examination purposes has been obtained. The
feed grain size up to a maximum of 50 mm
and the feed quantities depend on the relevant
type.
ADVANTAGES
Dividing without major expenditure of time
Simple and quick to clean
Usable in the laboratory and on site
Dividing process to DIN 51701, Part 4
High-precision manual dividing process
Inexpensive

SAMPLE DIVIDING
RETSCH SAMPLE SPLITTERS
ARE AVAILABLE IN 6 SIZES.
The choice of unit will depend on the feed size
and sample quantity. Because of the volume of
the two collecting dishes, in the smaller types
RT 6.5 and 12.5 the maximum feed quantity is
about 5 litres and in the larger types RT 25 –
75 about 16 litres.
Fraction of max. grain size
Grain size factor
Depending on the grain size, material and grain
size distribution, the opening width of the passages should be 1.5 – 3.5 times greater than
the diameter of the largest grain (grain size
factor).

With sample splitters the feed material is poured
with one of the dishes evenly distributed into
the dividing head. The material runs through
the alternately arranged passages in the opposite direction into the two collecting dishes
standing under the dividing head outlets. With
every operation the feed sample is halved. This
can be repeated as many times as necessary
until the required dividing quantity has been
obtained. The dividing head of the types
RT 6.5 and 12.5 is made of stainless steel, the
stand is of painted sheet steel and the collecting dishes of tin plate.
In the types RT 25, 37.5, 50 and 75, the dividing head, frame and collecting dishes are of
hot-dip galvanized sheet steel. Thanks to the
open design, the sample splitters are especially
easy to clean.
