Newest,
Biggest TrueBlend™ Blenders from Conair
Mix as Many as Six Materials at Rates to 14,000
lbs/hr
Since
the recent introduction of the innovative Conair
TrueBlend™ gravimetric blenders, hundreds
of them have been sold. Now high-volume plastics
processors can realize the benefits of these powerful,
easy-to-use, leak-proof blenders. Ideal for large
extruders or central blending applications, the
new TB1800, TB2500 and TB3500 Series blenders
can process as many as six different natural,
regrind and additive materials at rates to 7000
lbs/hr, 10,000 lbs/hr and 14,000 lbs/hr respectively.
Throughputs rates this high position these blenders
among the largest available in the world.
The
new, larger models feature the fully enclosed
weighing and mixing section that makes
the TrueBlend unique in the industry. When the
full-length access door is closed, all pellets
are contained. Other features developed especially
for high rate applications include larger dispense
valves, steep-sided material bins and more aggressive
mixing. Flow- enhancement devices (vibrators and
augers) can be added when difficult-to-flow materials
are involved.
With
all ingredients contained and accounted for, the
Conair blenders can be accurate to within ±0.5%
of setpoint on colorant and additive weights.
No blender is more accurate. The standard microprocessor
control adjusts after every dispense cycle, compensating
automatically on the next weighed batch for normal
variations in dispensing, as well as for resin
bulk density and particle geometry. After ingredients
are dispensed and weighed, they are dumped into
a mixing chamber, which holds multiple batches
of material. These individual batches are mixed
for a set time, averaging out any specific batch-to-batch
differences before the blend finds its way to
the machine feed throat.
All
TrueBlend units come with an ultra-simple
control system that features a user interface
with an easy-to-read 5.7-inch LCD touch-screen
panel with full color graphics. All setpoints
are displayed simultaneously, so setup is quick
and easy. The user enters the percentages of the
blend on the touchscreen display and the blender
does the rest, automatically weighing the recipe
ingredients in the proper sequence and maintaining
the correct blend relationship. For very critical
low-volume materials, where variations of a pellet
or two can affect the accuracy of the blend, the
controls can be set to the Precision Additive™
mode, which gives priority to the weight of that
minor component. Then, dispense weights of natural
resin and all other ingredients are adjusted accordingly.
Up
to 50 recipes can be entered and stored in the
control for instant recall. Options include an
integrated blender/loader control feature.
