There are less expensive plastic blades
available. Based upon in plant trials, the patented scoop
design makes the difference between an adequate blade and
a high performance blade. If it doesn't have 9 scoops on
each side then it's not the Polyblade.
How can it possibly work better than
metal blades with teeth?
The teeth are there to promote
axial flow, not grind. When spinning at high speeds these
teeth create a wall around the flat surface or shear zone
of the blade forming a barrier that slows the speed of the
liquid as it turns axially and flow up the side wall of
the tank which is the main shear zone. The teeth absorb
some of the energy which is why they can wear. They can
also bend and break which further inhibits shear from occurring.
The Norblade is designed with an end to end radial scoop
that propels the liquid as it leaves the flat surface of
the blade thus increasing velocity and promoting shear.
The pumping power is so efficient that the blade is able
to effective move the liquid at slower speeds during the
powder additions. The improved process time for incorporation of powders significantly
cuts down on overall batch time.
of the major coatings companies in the US are using the
Polyblade for safety, improved production times or abrasion
resistance. It may sound too good to be true. Sometimes
it is. Most times it isn't. Give us a call. We'd like to
get you started on your trial.
