new blender-design concept
(photo, p. 32I-9) that is said
to " markedly " reduce the energy
requirements. The design
of the impellers causes
a continuous flow through
the vessel and divides it into
two zones; one of intense
back mixing and another
area of high shear intensity.
The solid is wetted in
the backmixing zone while
complete dispersion of the
product occurs in the shear
area with plug-flow characteristics,
which leads to consistent,
high product quality,

A large pressure filter is
now two times bigger
This company has scaled up
the proven Larox pressure
filtration (PF) technology
to larger scale. The Larox PF 180 series
filters (photo) are now 50% larger
than the previous model. The PF 180
is almost 9 m long, 9 m high and has
a maximum filtration area of up to
252 m2. Filtration cloth of the PF 180
is continuous with only one seam and
is 200 m long. The automation system
of the PF 180 has also been upgraded
with interactive self-diagnostic features,
user manuals and an electronic
spare-parts catalog with 3D images.

Large, rubber-lined bends for
transporting abrasives
Piping-bends up to ND 900 from rubber
incorporating a seamless, highly
abrasion-resistant inner rubber layer
(photo) completes the range of this
company's products. On display at the
company's stand will be a bend of dimension
ND 600. Rubber bends have
proven themselves in conveying applications
for highly abrasive suspensions
in the chemical industry, mining and
environmental areas. Rubber bends
provide a much higher lifetime under
chaffing conditions than bends made
of other materials, says the manufacCircle

turer. The process for fabricating these
bends allows for continuous configuring
of both the bend radius (from 1.6 
ND to 6  ND) and bend angle (from
15 to 105 deg.). Hall 9.0, Stand D22 -

Liquid jet pumps do more
than create a vacuum
This company has opened up new
fields of applications for liquid jet
pumps in which the pump is not only
used to generate a vacuum, but at the
same time to scrub gas and separate
dust (photo, p. 32I-11). In the new application
presented at Achema, HClladen
exhaust gas is extracted from a
tumbling dryer and scrubbed until the
exhaust meets TA-Luft requirements,
with simultaneous generation of a 50mbar
vacuum. The jet pump is made
of conductive polypropylene (PP) with
glass-fiber-reinforced plastic, and
is offered as a compact unit that includes:
a separator made of PP, motive
fluid pumps of perfluoroalkoxy (PFA)
and plate heat exchangers made of titanium.
