DIGI-BLEND™ precisely
controls the blending of virgin and recycle materials to obtain
exact job specifications of the produced asphalt
mix. The system controls start/stop and rate for both liquid
asphalt and recycled material based on virgin aggregate flow.
It provides
full automatic or true manual (backup) operation which is totally
independent of the electronics. DIGI-BLEND™ is
compatible with plants having liquid asphalt meters that provide
industry standard
1000 PPG (pulse per gallon) output and belt scales that have
industry standard milli-amp outputs (4-20 or 0-20 ma).
DIGI-BLEND™ has single control
board design which provides control functions usually handled
by multiple circuit boards
in other systems. The single control board’s visual display
features help a qualified plant electrician determine if the
system is operating satisfactorily and provides clues as to
what other equipment may have caused plant malfunction. DIGI-BLEND™ design
concept also eliminates the requirement of a factory trained
technician to recalibrate the control board when a plant
is moved to a new location or if replacement is ever required.
DIGI-BLEND™ includes pre-wired operator panel, control
electronics and complete true manual backup.
