Up to 17 fractions (16 test sieves plus collecting pan with a height of 25 mm), 9 fractions (8 test
sieves plus collecting pan with a height of 40 mm or 50 mm), or 7 fractions (6 test sieves plus
collecting pan with a height of 65 mm) can be clamped.
NOTICE
A high number of test sieves can significantly increase the total weight of the load
(sieve stack and sample material). Make sure not to exceed the maximum payload of 20 kg.
Different sieve clamping units and lids are available for the test sieves.
The following sieve clamping units are available for test sieves with an outer diameter of
305 mm (12") and 400 mm:
"standard"
Ø 305 mm
"comfort"
Ø 305 mm
"standard"
Ø 400 mm

Types of the sieve clamping unit
For test sieves with outer diameters of 100
– 203 mm smaller clamping lids must be used. For
further information please contact your supplier or get in touch with Retsch GmbH directly.
5.1 Sieve Clamping Unit "standard"
Screw one hexagonal nut (
G
) on the lower end of each of the threaded rods (
A
).
Screw both threaded rods (
A
) into the designated threaded holes (
SB
) in the sieve plate (
ST
)
and lock them with the hexagonal nuts (
G
).
Firmly tighten the hexagonal nuts (
G
) by means of a 19 mm open-end wrench.
Place the desired
including the sample material centrally on the sieve plate (
ST
).
Lay the clamping lid "standard" (
D
) over the threaded rods (
A
) onto the top test sieve. The
clamping lid "standard" is orientated so that the peripheral edge surrounds the test sieves.
Slide the fixing nut (
B
) in an inclined position of 10° down the threaded rod (
A
) onto the
clamping lid.
Align the fixing nuts (
B
) vertically so that the thread engages and tighten the fixing nuts
hand-tight.
