Designed
as a high speed, high shear mixer and emulsifier for continuous
processing, the DynaShear sets the standard for
what in-line mechanical mixers should provide. It is constructed
completely of 316SS (internals, housing, shafting and
base), it's unique dual stage axial and radial heads provide
greater throughput and flow, and the shear rates generated
insure droplet and particle size reduction down to 3-5
microns with excellent distribution.
Some processors are using
DynaShear for a single pass continuous mix after powder
addition upstream, while others have found maximum results
after recirculating back through a batch reactor for a
3 to 5 minute total blend time.

How
It Works
The performance
and success of high shear in-line mixers can be measured
in droplet size (particle size) reduction, particle size
distribution and flow / processing rates under varying
viscosity conditions. The DynaShear excels in all of these
characteristics when compared to competitive in-line mixers.
A
single pass through the DynaShear provides product
quality typical of multiple passes within conventional
mixers!
|
|
The DynaShear
is the first in-line mixer featuring a dual stage, tandem
head design combining the benefits of both an axial and
a radial stage
creating excellent shear and flow
characteristics.
Primary Axial Stage:
The
axial stage consists of a high flow rotor feeding into
a stator with multiple small ports, forcing material between
their faces and out through the ports. This mechanical
and hydraulic action causes a tremendous shearing action
and "pre-mixes" the material prior to the secondary
stage.
