The TrueBlend Blender meters and mixes free-flowing plastic granulate (regrind and natural
material) and additives. The unit mixes four to six materials, depending on model and con-
figuration. The unit meters each ingredient into a gain-in-weight material batch hoppers
with mounting flanges for one hopper loader each. All components are dispensed by pneu-
matic vertical cone valves and are fed into the weigh bin, which is mounted on a load cell.
The pneumatic cylinder opens the weigh bin. The mixture (batch) falls into the mixing
chamber and is mixed and agitated by an electrically powered mixer into a homogeneous
state. The mixing chamber holds three batches. After mixing, the chamber is emptied by
the discharge slide gate into the injection or extrusion process.
Next, the vertical valves
dispense the pro-
grammed amount of
material into the weigh
bin.
The load cell deter-
mines when the batch
is complete, and the
pneumatic cylinder
drops the batch into
the mixing chamber.

Note
: After the slide gate discharges the mixture, approximately one batch remains in the mixing
chamber to ensure that the next batch can be optimally mixed.
