Generator
(set of rotor / stator)
In order to configure a machine
to meet a variety of application needs, IKA offers
a wide selection of rotors and stators (generators)
for all machines. Different generator designs provide
a combination of varying levels of dispersing energy.
In addition, they are also designed to accommodate
materials of different viscosities and initial particle
size. In-line rotor-stator (generators) are designed
differently than those for batch machines because
there is less of a requirement for pumping, as there
is in batch mixing.
It is important to note that the differences between
the coarse, medium, fine and other generators is not
only the number of rotor and stator teeth rows. There
is also a significant difference in the geometry from
one generator to the next. The number of slots, width
of the slots, and other geometric features will also
change to define the performance of the generator.
The
following are examples of generator designations,
and a description of the generator and typical applications:
It is normal practice to specify a generator for an
application based on prior experience. In most cases,
the machine is configured for a specific application,
so it is important to have an understanding of the
product. When it is uncertain if a generator configuration
will perform according to expectations, it is always
recommended that a trial or test is performed in the
laboratory. IKA encourages customers to utilize our
facilities, and a complete line of trial machines
are available for testing at the customer’s
facility.

2P
(axial fins pumping rotor) |
Coarse
stator |
|
Moderate
shear for general purpose blending and homogenizing
processes. Coarse Stator combined with pump
fins pumping rotor (2P): A coarse stator is
used with a specially designed rotor that provides
high throughput, designated “P”.
This generator will provide throughputs up to
four times higher than any of the other generators.
The generator produces moderate shear, and a
high pumping effect. It is often used in place
of a pump, or to assist a pump for improved
flow. This generator is also used in multiple-stage
machines to assist in the flow of high viscosity
fluids.
Typical application: Miscible liquids, large
agglomarates, high circulation rates, and shaer
sensitives process fluids. |
Coarse rotor and stator: |

2G
rotor (coarse) |
stator
(coarse) |
|
Coarse
(2G): Impacting, shredding, dissolving, and
coarse fragmentation. It serves especially for
pre-crushing of coarse-grained suspensions as
well as for shredding and impacting of resins.
|
Medium rotor and stator: |
|
 |
4M
rotor (medium) |
stator
(medium) |
|
Medium
(4M): Impacting, pigment dispersion, solution
acceleration, and fine fragmentation. It is
a universal-mixing tool for emulsions and suspensions,
especially in the field of pigment processing,
and is preferably used in the low viscosity
range. |
Fine rotor
and stator: |
|
 |
6F
rotor (fine) |
stator
(fine) |
|
Fine
(6F): Impacting, reaction acceleration, solution
acceleration, and very fine fragmentation. Especially
suitable for micro-emulsions and suspensions,
which are commonly used in lotions, creams,
or inhales. Mainly used for the low viscosity
range, or in connection with a feeding pump. |

provides highest Quality: Automated
machinery guarantees the precision manufacturing required
by IKA’s standards.
|
 |
The
distances between the rotor and the stator
are from 0.25 to 0.8 mm. IKA machines allow
this small of a gap because of precision
machining and high quality standards for
all IKA machines. All IKA generators are
machined on computerized numerical control
machines.

All IKA products go through a series of demanding
quality control checks. Every product that goes through
our doors has exceeded our quality standards and carries
the IKA® Guarantee.
