5-8-3 Mix Timer
The mix timer is the amount of time that the mix motor will mix the
material after it has entered the mixing section of the SGB blender. The
timer has a range of 1 to 999 seconds.
To set the value of the mix timer, the user must gain access to the Setup
Menu. After entering the Setup menu, the user must select “Mixer and
Dump Setup.”
Selecting “Mixing Time” from the “Mixer and Dump Setup” menu will
allow the operator to view the current time setting for the mix timer and
to adjust it as needed.
The mix timer is set to a default time of 10 seconds. This time can be
adjusted up or down depending on the amount of mixing needed for the
materials being blended.
It is recommended that the mix time be held to the minimum, as
segregation can occur from over-mixing if the material bulk density and
pellet configuration varies with materials in the particular blend being
processed.
5-8-4 Re-Mix Timer
In some applications, the SGB blender will require the use of the re-mix
timer. Some materials tend to separate if they are mixed too long. This is
possible when a processing machine is running at a rate significantly
below the capacity of the blender.
With external vibration, the heavier pellets will tend to flow to the bottom
of the mix chamber before the lighter material. This will occur even
though the mixer is in a static mode. By re-mixing occasionally, this
situation will be prevented.
The re-mix timer will start another mixing cycle if the blender has been
idling long enough for the re-mix timer to time out. The re-mix timer may
be set on the “Mixer and Dump Setup” screen from 1 to 999 seconds.
Setting the re-mix timer to zero will disable this function.
If the re-mix timer is disabled, the controller will run only a single, timed
