5.3. Installation of the SONO-MIX MINI inside a Screw Conveyor
The installation of the SONO-MIX MINI inside a screw conveyor ensures optimum conditions
concerning material flow and material density, because the measured material is not loose but is
condensed by the screw.
The SONO-MIX MINI can be installed along the screw conveyor. It is recommended to attain a
mounting angle with a limit value of 30°, to ensure that enough material lies above the probe´s surface.
Optionally the spiral conveyor can be cutted, so that a plug formation ensures that enough materials lies
above the probes´s surface. It is also possible to install the probe at the end of the screw conveyor,
where it is also ensured that enough material, in a backlog with a relative constant density lies above
the probe´s surface.
It is recommended to use
measurement mode CF
if the spiral is cutted out of if the probe is installed at
the end of the screw conveyor.
Furthermore it is possible to install the SONO-MIX MINI in the middle of the screw conveyor without a
cut out of the spiral. Here it is necessary to set appropriate filter algorithms, because the metal of the
spiral has an influence of the measurement. The appropriate parameters have to be found, dependent
on screw velocity.
It is recommended to use
measurement mode CK
if the probe is installed in the middle of the screw
conveyor without a cut out of the spiral.
5.3.1. Installation of the SONO-MIX MINI in a mobile Mixer Truck
When installed the SONO-MIX MINI in a screw conveyor inside a mobile mixer truck, it is possible to
measure sand moisture very precise. So a reliable recipe accuracy is guaranteed.
