Applications
VOLLRATH-Dispersers are mainly
used to disperse pigment,fillers
and other powders into liquids or pastes. The large agglomerates
being broken down and the solid particles wetted out.
Principle
The principle of the VOLLRATH
High Speed Disperser is to use
a specially shaped toothed disc
at a very high peripheral tip
speed. This ensures that large
stress forces break down the
agglomerates into the liquid or
paste suspension.
High performance and efficiency
The high power density, the large seed range and the constant
power of the variable speed frequency inverter drive gives the
VOLLRATH-Disperser excellent efficiency and maximum flexibility,
along with the built-in overload control, which ensures safe and easy processing of all products.
Optimisation
To create maximum shear rate at the premix stage the product is normally worked into a high viscosity
liquid or paste, before adding the rest of the liquid, which had been held back.
The following options can be supplied by VOLLRATH to optimise the processing:
– Higher viscosity products are best processed with the Disperser-Suction-Disc to move the whole batch
–
efficiently.
– Other types and sizes of disc can also be used to suit the particular product to be processed.
– Wall and bottom scraping systems can be added – when the Dispersers are used with a wall and bottom
– scraper, highly viscous products can be easily processed.
– Vessels can be fitted with heating or cooling jackets.
– Dispersers with conical vessels are normally supplied when a large variation in batch sizes or the
whole
– process has to take place in one vessel.
– VOLLRATH can also supply Disperser of special execution that can be developed with the customer.
– Universal - Mixing - Dispersers with up to three mixing systems, like the Type VDMP, can be supplied
for a
– wide range of products.
Laboratory and Trials
The VOLLRATH-Laboratory and demonstration room is available for trials to ensure correct selection of
equipment to suit customer’s particular requirements.
An adaptation of formulation can be necessary to reach optimal results.
Explosion-proof protection (ATEX)
Dispersers can be supplied according to EC Directive 94/9/EG
(ATEX)
for use in all zones including zone O. Notified body (PTB)
certificates
are available where required.
Vacuum-Dispersers
The option “vacuum” is available for the
most VOLLRATH-Dispersers.
Construction and Service
All VOLLRATH-Dispersers are solidly built
and designed to give a trouble free long
service life.
Universal-Mixing-Disperser
The “VOLLRATH-Mixing-Disperser” is a universal device
ideal for the
processing of higher viscosity products with
scraper, disperser and
mixer.
Using all three elements; the slow speed rotor to incorporate
the
ingredients into the batch; the high speed disperser to
break down
and disperse powders into the liquid; the
anchor with wall and bottom
scrapers to clear the vessel
surfaces of product and feed the product
into the working
areas of the mixer and disperser.
This ensures a quick and homogeneous processing.
Using just the
rotor
and anchor, and if required with the disperser running slowly more
more delicate additions
to the process can be added without damaging them.
Higher viscosity products up to approximately 700,000 mPas including adhesives, fillers, sealing compounds,
foundry coatings, decorative plasters, masonry paints, primers and dispersion paints, can be
easily processed
with the “VOLLRATH-Mixing-Disperser”.
