Gravimetric Batch Blenders w/Mitsubishi Control Chapter 4: Operation 64
5. If you want to catch the color, use a small plastic pail or chute to collect the material
from the slide gate assembly. Reach up inside the blender to the color slide gate and
push it open. At this point, there should be no air pressure on the blender, and the
slide gate should move easily. Drain the color out in the bucket. Blend and Reclaim
normally provides a JIT (Just in time) approach to the minor ingredients, so that a
minimum amount of material is held in the blender so that color changes can be made
easily.
6. If any other ingredients need to be changed for the next recipe, simply drain the
larger hoppers with the drain tubes provided on the side of the hoppers. When the
material level is below the drain tube, open the slide gate manually to dump the rest
of the material. If you wish to speed the emptying process, material can be manually
drained out of the slide gate assembly into a dump chute or bucket, while draining
from the drain tube.
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.
Note: 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.
WARNING! 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.
