ROTAP SIEVE SHAKER
RO-TAP® RX-29 AND RX-30 MODELS
The industry standard in test sieve shakers, the original W.S. Tyler Ro-Tap® has a unique two-dimensional operation: a horizontal, circular motion, and a vertical tapping motion.
This special action allows material particles to stratify and “seek” critical openings in the test media. This unit provides the
most accurate and consistent particle analysis testing and requires minimal maintenance.
The RX-29 is designed for testing with 8-inch diameter test
sieves. The RX-30 model is designed for testing with 12 in. diameter test sieves.
Each unit is test run and serialized prior to shipment and features a 99-minute digital timer/clock with a tolerance of .1
seconds.
SPECIFICATIONS:
Oscillations per Minute 278 ± 10
Oscillations Displacement 1-1/8 in. x 7/16 in.
Taps per Minute 150 ± 10
Dimensions 28 in. wide x 21 in. deep x 25 in. high
(71 cm x 54 cm x 64 cm)
Weight 180 lbs. (82 kg)
Testing Applications RX-29: 2 in. through US #635 mesh (20 μm)
RX-30: 4 in. through US #500 mesh (25 μm)
RO-TAP® RX-94 MODEL
The RX-94 Test Sieve Shaker utilizes the same traditional design as the RX-29 model. In addition, the unit features a
cavity that allows for two “stacks” of 8 in. or 200 mm diameter test sieves.
This allows for twice the processing capacity in nominally the same time required to complete one test. The RX-94 model is designed for use with 8 in. or 200 mm diameter test sieves only and feature a newly designed easy lock
clamping system.
Each unit is test run and serialized prior to shipment and
features a 99-minute digital timer with a tolerance of .1 seconds.

Taps Per Minute 150 ± 10
Dimensions:
30 in. wide x 27 deep x 26 in. high

The newly designed Rotap E Test sieve shaker stands out with its simple and quick operation. Two specific regulated
amplitudes for coarse or fine material
can be selected by the user. Sieving
begins immediately once the timer is set
and an amplitude has been selected.
The Ro-Tap E is recommended as
a basic machine for standard sieve
analysis.
The Ro-Tap E Premium unit is one of two
new W.S. Tyler Sieve Shaker offerings.
This machine is our most quiet design
ever with the improved dampening
system. The control panel allows users to
self select the amplitude and interval of
the sieving motions.
The extra large display offers operators
an excellent overview of the settings
and is user-friendly. The new Ro-Tap E
Premium unit is ideally suited for users
who demand precision and reproducible
sieve analysis.
The Ro-Tap E Premium Remote offers
a separate control unit for wet sieve
analysis. The design and function of
the lid has been specifically developed
for tests where water needs to be used
to assist in the particle separation.
The wide-spreading spray diffuser
is integrated into the cover, offering
improved handling. The cover includes
an inspection glass which allows
observation during the sieving process.
Designed to be used in coarse testing
applications, the affordable RX-812
coarse sieve shaker has the unique
capability of using both 8 in. and 12 in.
diameter test sieves, simply by using
the quick-change adapters provided.
The RX-812 has a quiet operation and
utilizes an effective action that gives
consistent accurate results. The RX-812
is recommended for use with test sieves
100 mesh and coarser.
