MIKRONS� Multi Shaft High Speed Disperser
MIKRONS® Dual-Range can be employed to work
on high pigment concentrations which gives rise to finer and faster
dispersions eliminating conventional milling on many products.
One motor and variable speed drive powers both shafts.  The
disperser blade is a disc impeller available in stainless steel.
The heavy-duty impeller is a 3 blade open impeller. This machine
is equipped with an adjustable vessel holder that holds the vessel
in position during mixing. Vacuum designs are also available.
These machines will increase productivity and versatility of high
viscosity batch processing. They are suitable for mixing and dispersing
materials with high viscosity in excess of 100,000 cps that tend
to stick to the wall of the mixing vessel. The high speed blade
will disperse the materials at a tip speed of 5200 feet per minute,
while the large open type impeller, rotating in the range of 300
to 1300 feet per minute, will keep the high viscous materials
flowing. This system produces swift dispersions in applications
from paste inks to coatings, plastisols, adhesives, caulking compounds,
and specialty chemicals.
Disperser-Homogenizer: No matter how viscous
or resistant the mix materials are, our customers are assured
to get a smooth and homogenous product in the minimal time with
high thermal efficiency. Ideal for use in the chemical, plastics,
paint, rubber, pharmaceutical, and food processing industries.
Three stages of Operation: A broad choice of
impellers on three different shafts handles viscosities greater
than one million centipoise. A typical combination includes a
low-speed MIKRONS® impeller, an efficient MIKRONS® auger
blade, and a high-speed MIKRONS® impeller-disc, or a MIKRONS®
rotor/stator.
 1. Mixer:
a slow speed open impeller with three risers starts the batch
moving and continually forces it into the thinner high speed blades.
Risers usually have scrapers to clean the tank walls increase
heating and cooling efficiently.
2. Dispersion - a high-speed disc with
sharp teeth breaks up agglomerates or masses when they hit the
disc or each other in the intense zone of attrition.
3. Homogenizing - a high-speed rotor-stator
further separates the batch into smaller droplets of mutually
incompatible material and forces them into a mixture.
Efficient & Versatile - The impellers are lowered
and raised hydraulically. For convenience in discharging the product,
the entire mixing chamber can be elevated hydraulically. A hydraulic
power supply and controls for operating the lift are located in
a separate chamber. Chamber capacity, motor horsepower, shaft
speeds, impeller combinations, and construction materials can
be selected to meet customer application.
