street," says Legg.
While Legg and the City and
County of Denver have large crews
working in street maintenance,
there are usually only two people
operating the ProSizer® 3600 plant.
With a small team and limited
experience, operating the new
machine was unfamiliar territory.
The team began crushing in April of
2018 and quickly mastered running
the machine.
"The Prosizer® plant has been
very easy to learn and operate. The
crew was up and running with the
machine within two days of it being
set up," explains Legg.
Smallwood adds, "We began
operating this plant early this year
and the City and County of Denver
has stayed consistent in the 250300 tons per hour range...The City
needed a plant that could kind of
be a jump start that they wouldn't
have to run every day, all day, seven
days a week. They can keep up with
their aggregate demands, working
four, 10-hour shifts with minimal
issues."
"The heart of this operation is
the ProSizer® 3600 impactor plant,
manufactured by Astec Mobile
Screens. It's equipped with a 14'
vibrating grizzly feeder, a 2-bar,
36 x 46 horizontal shaft impactor,
two adjustable hydraulic aprons
and then the material is discharged
or fed into a 6 x 18, 2-deck high
frequency
screen,"
explains
Smallwood.
Legg also expands on the
impactor plant and its reliability
in processing RAP, "The plant fits
the RAP environment very well.
With the high angle screen, we get
very little blind over on the screens
