Continuous Loss-in-Weight Blenders Chapter 3: Installation 28
3-5 Overall Installation (Summary)
This installation procedure should be used as a general guideline for the proper installation
steps required to install the continuous loss-in-weight blending system.
1. Visually inspect the extruder or blender mounting location for obstructions.
2. Remove the material supply hopper on the extruder flange.
3. Carefully lift blender into place above the mounting flange on the extruder and fasten
the blender to the flange using the extruder flange bolts.
Note: Always lift the blender from the eyebolts on the top plate.
4. Mount the weigh hoppers that were shipped in boxes on the crate, to their respective
load cells (Don’t forget the plastic dust cover on the bottom of the weigh hopper).
Align the discharge tube on the weigh hopper to be centered in the lower frame
opening over the feeder assembly. Use caution in tightening the bolts. Adjust the
gap to 0.040”.
5. Hook the manual mode level sensor bracket over the lower mass flow weigh hopper
on the bottom of the blender. Ensure that the cord is not binding on anything that
would affect the accuracy of the weigh hopper.
6. Check the wiring from the load cells to the control panel.
7. Ensure that the motor power cords are connected to each of the metering unit motors.
Note: Ensure that the augers on the blender metering units are not bent or damaged
in shipping before starting the unit.
8. Connect the control power to the motor control panel.
9. Connect the compressed air piping to the inlet fitting on the top of the blender top
frame. Ensure that the air supply is regulated to a maximum of 60 PSI.
Note: Ensure that the compressed air is regulated to 60 PSI max.
