to compensate for the inconsistent mixing along with
4. The variable dampness would confuse the nozzleman
adding and subtracting water as well to compensate for
Thus, there was no coordination between the gunman
and nozzleman keeping the mixture predampened properly.
Customers said hydro-mix nozzles do work with lower
volume applications, but as they increased material flow,
the extra water introduced into the mixture would ball up
the material into clumps and plug the nozzle on exit. They
referred to this problem as a “snot ball” effect. Initially there
would be a good flow of material but then there would be
a slow buildup in the hose and nozzle that would eventually
break loose and blow out in the form of a big snot ball. This
process would always repeat itself during the shoot.
Canusa Equipment’s customers wanted something that
would do a better and more efficient job than the existing
equipment. The company developed a machine to address
their concerns that has exceeded their expectations. Predampening
dry material properly controls the dust around
the machine, improves visibility for the nozzleman, reduces
equipment wear, and reduces static electricity. A major
benefit in productivity is reducing the amount of rebound
with better hydration of the dry materials.
Not only will the
PDM-1 predampener do all this with dry-mix materials,
but it can also be adjusted for wet-mix applications.
When a jobsite engineer requests certain parts of the
project to be done with the dry process, and a different
section to be shot wet, the PDM-1 predampener can do
and correctly. Performance, consis
