Principles of Operation
In the KM static mixer, a patented helical mixing
element directs the flow of material radially
toward the pipe walls and back to the center.
Additional velocity reversal and flow division result
from combining alternating right and left hand
elements, increasing mixing efficiency. All material
is continuously and completely mixed, eliminating
radial gradients in temperature, velocity and
material composition.

Mixing Applications
Our static mixers provide precise blending and
dispersion of all flowable materials, without
utilizing moving parts. Mixing is achieved by
redirecting the flow patterns already present in
empty pipe. Kenics static mixers are currently
being used in numerous processing applications,
in order to reduce overall cost and significantly
