5.2 Brief description of the functional units
(Item numbers refer to diagram on previous page)
The TrueBlend meters and mixes free-flowing plastic granulate (regrind and
natural material) and additives. The unit mixes four to six materials, depending on
model and configuration.
For example, the unit has four material hoppers [2] with mounting flanges for one
hopper loader
4
[1] each. All components are dispensed by pneumatic vertical
cone valves [4] and are fed to the weigh bin [13], which is mounted on a load
cell [11]. The pneumatic cylinder [12] opens the weigh bin.
The mixture (batch) [5] falls into the mixing chamber [10] and is mixed by an elec-
trically powered mixer [8]. The mixing chamber holds three batches. After mixing
the batch [9] the mixing chamber is emptied by the pneumatic discharge slide
gate (remote mount) [7]. Approximately one batch remains in the mixing chamber
to ensure that the next batch can be optimally mixed.
The operation of the TrueBlend is by a PLC controller. The controller receives a
signal to feed material from the capacitive level sensor [6] in the mixing chamber
(see also 9.5.1 Adjust or replace level sensor).
