7. Using a vacuum cleaner or air hose, clean out all the hoppers that have been emptied.
Always start at the uppermost part of the blender and work downward to prevent dust and
pellets from falling into an already cleaned area.
WARNING! The auger metering assemblies on Auger blenders can be removed after the
hoppers above them have been drained.
8. Clean the weigh hopper and mixer assemblies on the blender using a vacuum cleaner. The
mixer agitator is removable for cleaning if desired.
9. Reinstall any metering units that were removed from the blender during clean out.
10. Reinstall the weigh hopper using care to center the hopper on the load cells on the weigh
hopper bracket.
11. Load the blender with new material.
12. Restart the unit with the new recipe.
DANGER! Always disconnect and lockout all electrical power and pneumatic (i.e.
compressed air) sources prior to servicing or cleaning any product, including all
Slide Gate/Auger blending systems. Failure to do so may result in serious injury
or death.
4-3 Shut-down
The Slide Gate Gravimetric Blender can be stopped in one of two ways:
1. To immediately stop the blender, the operator can touch “Abort Current Batch.” This will
cause the blender to stop making the current batch immediately. Obviously, if the blender is
stopped in this method then the current batch will not be completed properly.
2. If you would like to complete the current batch of material before shutting down, then you
can wait until the Inventory Shutdown value is reached. The blender will finish the current
batch of material to the specifications set in the Setup portion of this manual. It will then
stop and display that the inventory value has been reached. Additionally, it will flash an
alarm and wait for operator attention. An example of this screen is shown below:
