Gravimetric Batch Blenders w/Mitsubishi Control       Chapter 4: Operation

Feeder Clean Out 
Any feeder in the Slide Gate/Auger blending system can be emptied and refilled with a 
different material. To do a feeder clean out, the operator has to press the “Clean Out” icon 
key from the recipe screen (the first screen that appears on power up).   
This screen will allow you to Open or Close the Feeder, Weigh Hopper, Mixer Knife Gate, 
Empty the Entire Blender, Start or Stop the Mixer Motor, Test the Alarm Output, Find out the 
Mixer Proximity Status and monitor the Current Hopper Weight. 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
The dump valve opens as soon as the “Press to Open Feeder” key is pressed. This easy feeder 
clean out option also serves as a means for emptying a batch that is held in the weigh hopper 
if the “Press to Open Weigh Hopper” key is pressed when the blender is stopped. To 
open/close feeder numbers 2, 3, 4, 5 & 6 press the number next to “Press to Open Feeder” to 
select the feeder you desire to empty and the “Press to Close Feeder” key to close the dump 
valve.  Touch the “Done” key to return to the recipe menu. After entering a recipe, the 
operator will restart the blending system, putting it back in normal operation. 
Note:  Before starting Slide Gate/Auger blending systems, each ingredient hopper in 
the current recipe must contain material!  Virgin material must be loaded in 
hopper #1 and hopper #3 should only be used for regrind!! 
Once the operator initiates the run mode of operation, the blending system controller will 
begin monitoring the mixer high-level switch. Nothing will happen until the mixer high-level 
switch is uncovered. This tells the controller that the mixing chamber is capable of holding 
another batch of material. 
Once the mixer high-level switch is uncovered, and the weigh hopper has dumped, the system 
will meter the ingredients from the supply hoppers, through the metering units, into the weigh 
hopper. Each component will be metered individually to allow accurate weighing of the 
material. 
Each component is metered in the order specified by the “Metering Order” setup. See the 
Installation & Setup chapter for further details. 
Once the final ingredient specified in the recipe has been metered into the weigh hopper, the 
controller will take a final weight reading of the weigh hopper. This will start the “Dump 
Delay” timer. (See Page 50). Once the dump delay timer has timed out, the controller will 
activate the weigh hopper dump valve, initiating the weigh hopper dump cycle.
