Get accurate blends, better mixing, faster material changes and
increased profits with Conair's TrueBlend Series Blenders. Steepsided component hoppers allow material to flow evenly and freely
through vertical dispense valves into the weigh chamber. Efficient
mixing assures full integration of all recipe ingredients. The fully
enclosed cabinet design assures no pellet spillage and clean operation. Standard convenient features such as wide access doors
on each main material compartment, a hinged access door and
removable components in the mixing chamber reduce downtime
during cleanout.

The TrueBlend TB250 series blenders
offer processors with medium-sized extruders or large tonnage injection molding machines a superior way to blend
color and additives centrally or at the
throat of the processing machine.
The blender dispenses up to six materials
(depending on model) from material
compartments into a common weigh
chamber. The control determines the correct weight of each ingredient based on
setpoints entered on the touch screen
display. Up to 50 recipes can be entered
and stored in the control.
Unique fast-acting "no stick" vertical
valves control the amount of material dispensed. All dispense valves use two-way
air cylinders assuring positive operation.
Choose between four component or six
component blender models. Options include an integrated blender/loader control feature, addition of a flow control
valve for central blending applications
and material compartment drainports.

Precision Additive feature is also available for additives. The microprocessor control automatically calibrates after every cycle and compensates for variations in
dispense method, resin bulk density or particle geometry.
