New Buck, Split-Valve Technology, Test Station Available
------------------------------------------------------------
Columbia, MD -Niro Inc. announced today that it will have a
Buck Test Station available from its office in Columbia, MD.
This unit allows users to test various products for containment
levels in their own facilities, or if preferred tests can be
conducted at Niro's Maryland facilities. The Buck Test Station
has the following features:
-Mobile (can be shipped to customer's facility)
-All valves size 8"
-Valve rated for pressures up to 4.5 psig
-Maintains seal against +29 inches of vacuum
-Valves manufactured of 316L stainless steel
-Containers also manufactured of 316L stainless steel
-Available with EPDM elastomers - Kalrez available on special order
-Valves have pneumatic actuators
-Results can be used in design to scale new systems up or down
Buck split-valve technology allows containers to maintain a
dust-tight seal while connecting with (and disconnecting from)
intermediate bulk containers and various process equipment
such as mills, dryers, blenders, presses, and compactors. The
design eliminates contamination of the product or leakage of
material that might endanger operators to less than 1 microgram/m3.
Buck technology is offered in North America by Niro Inc.
Niro Inc. is an international company specializing in the
manufacture of equipment for the production of materials in powder,
granulate, agglomerate, or tablet form. Niro products include
spray dryers and coolers, flash dryers, continuous and batch
fluid bed processors, rotary presses, evaporators, filtration
systems, homogenizers, mixers & one-pot processors, IBCs and
powder handling equipment, docking systems & valves, and
packaging systems.

Bead Mill with Particle Sizes Clearly Below One Micron
------------------------------------------------------------
New Standards in Wet Grinding
The dispersion and wet grinding of materials with a low
viscosity are among the most expensive process operations in
the production of fine chemicals. The ZR120 bead mill now
allows to achieve particle sizes which are clearly below one
micron.
The quality requirements that solids-containing materials used
in the chemical industry must meet have risen enormously over
the past few years. Many product characteristics such as the
transparency or color strength of coatings or the rheology of
suspensions greatly depend on the size of the particles these
products contain. The average particle size demanded is often
in the range of a few hundred nanometers. To optimally utilize
the solid matter, a narrow particle size distribution is
often required.
Small grinding media
In order to efficiently obtain particle sizes in the submicron
range, the trend towards using micro-grinding media (diameter
between 0.2 and 0.6 millimeters) has become widely accepted
over the past years. But to date, the application of
micro-grinding media has proved to be a problem whenever high
recirculation rates were required for size reduction processes
based on the recirculation mode of operation. The screens
commonly used for separating the fine grinding media may easily
clog, and the drag forces acting on the grinding media lead to
an uncontrollable pressure buildup and energy input. In
developing the ZR120 centrifugal mill, these problems were
elegantly solved by applying a moving screen and by separating
the grinding media from the product stream in a centrifugal
field.
Recirculation mode
Being mixed systems, bead mills will always have a relatively
wide retention time distribution. Narrower distributions can
be achieved by applying a pass-through mode of operation using
slot mills with low back-mixing and media of higher viscosity
(e.g. with concentrates on the Buhler K-series machines).
However, with micro-grinding media, low-viscosity media must
be used. Due to the recirculation mode of operation, the
retention time distribution of the mill will then lose its
significance as the number of passes increases. The higher
the recirculation rate in this process, the sooner the
necessary number of passes will be achieved that are necessary
for obtaining a narrow particle size distribution.
Wet grinding
To obtain an optimal wet grinding process using bead mills,
two central requirements must be met, which it has only been
possible to combine inadequately up to now: The application
of small grinding media for obtaining particle sizes in the
submicron range, and the recirculation mode of operation
with high recirculation rates for achieving a narrow particle
size distribution. The new ZR120 centrifugal mill has been
systematically developed by Buhler for wet grinding in the
recirculation mode. With about six liters of grinding media,
it allows recirculation rates as high as five cubic meters
per hour. Unlike other processes, more than two thirds of
the installed power of 45 kilowatts are used for size
reduction.
Innovative process zone
In a rotating drum, a centrifugal field is generated which
is 150 times stronger than the gravitational field of the
earth. This provides an elegant solution to the grinding
media separation problem. The intensity of the grinding
media contacts can now for the first time ever be selected
in the ZR120 independently of the throughput rate and
product viscosity via the bead pressure. Throughout the
production process, it is maintained at a constant value
by an automatic torque control system with the aid of a
fully automatic, busenabled control system. This allows
the energy input and recirculation time to be optimally
matched to the quality requirements of the end product.
The ZR120 is suitable for processing both solvent-based
coatings such as printing inks, automobile and industrial
paints and water-based suspensions of fine chemicals or
textile dyes.

Ross Introduces New Planetary Mixer Blades
------------------------------------------------------------
Bogard Lagman, Executive Vice President, today announced the
introduction of an entirely new blade design for the company's
line of Double Planetary Mixers. The new design is designated
as the "HV Blade and is available for all sizes.
The new HV Blade enhances the capability of the Planetary Mixer.
It enables the mixing of ultra-high viscosity formulations.
Products having this viscosity previously required a high
horsepower double arm mixer. The new Blade has many advantages
including the following:
-Capable of mixing products up to 10,000,000 cps.
-Assists in the rapid incorporation of light and difficult to
wet solids such as fumed silica.
-Cleans the walls and bottom of the vessel during the mix cycle.
-Easy to clean between batches and color changes
The "DPM" Model is available with a new range of optional
features including sanitary designs, special benches, and vacuum
and pressure sealing options. This mixer is equipped with
special start under load protection.
Ross Mixing, Blending, Drying and Dispersion equipment is
manufactured on five continents and is marketed worldwide. In
the USA Ross operates five plants.
