Overused urethane blade looks mean but
can be held without worry even by a child since points arc,
Our customers have told us that this is the most important
feature of our blade - it never gets sharp like metal blades..
Personnel will no longer get cut while changing the blade
or backing into the blade.
Even the most overused abused blade will still have flexible
edges that a child could hold without harm. It will be less
destructive on items which may fall into the batch preventing
it from splintering and flying into the face of the operator.
These blades are also bi-directional. They cannot be put on
backwards like other blades which can rip and fly off the
shaft or unscrew from the shaft while it is running.
Outlasts metal many times over. It
also outlasts other competitive polymer blades. Domestic companies
can take advantage of our 30 day free trial. If you don't
like the blade just return it.
Reduced Heat: Batches
will run cooler using the Norstone impeller which is important
with heat sensitive products. It will also reduce the amount
of algae formation in water systems.
Blade mounted with stiffening plates shown
after 15 months in a 40% Ti02 slurry.
The polymers are 100% organic. No metal contamination means
no discoloration or other imperfections caused by undesirable
metal in a product.
Improved Production Time:
These impellers do more work in less time because its third
dimension provides a high axial flow producing an aggressive
dispersing action. Because of this most applications require
a smaller diameter blade than is currently being used. It
speeds up production for faster batch turnaround.
These impellers initially cost more than a metal bade, however,
it has a low cost to wear ratio. In the long run these blades
cost less because there are fewer shutdowns for the operator
to change it as often and the batch production quality is
Double the blade's life with one quick turn. The following
edge on the blade will always wear first. Half way through
the life of the blade simply turn it over and the untouched
leading edge now becomes the new following edge.
