Description, Care and Maintenance
Venturi Mixing Tee
The Venturi Mixing Tee (Fig8a.) is the very heart of this system and requires very little maintenance.
However M-750 parts may wear as a result of the application in time and require replacement. This wear
will become evident, when the operator notices a reduction in the vacuum that helps pull in the dry product
from the hopper. When mixing dry product, over time, you will see an accumulation of damp product inside
of the mixing tee around the nozzle. If this accumulation is left unattended, over time it will build to the point
of restricting the inlet of the mixing chamber. This situation is easily rendered, by using the wash wand to
“flush out the accumulation” and force it back into the fluid stream.
