General Operation

The general operation of the Slide Gate/Auger blending system is as follows: Once the system is properly installed and set up, the system will be ready for operation. Please see the Installation and Setup chapter in this manual for further information.

Once the Slide Gate/Auger blending system is powered on, the unit will display the recipe screen (the recipe format should be in “Quickset” recipe mode). Pressing the highlighted box next to the feeder number, the operator can enter a valid recipe or use a previously stored recipe from the recipe book.

1.The blender is started by turning system on or material dropping below level switch in mix chamber.

2.Metering gates are opened (or auger motors are turned on) to meter material into the weigh hopper in the programmed order.

3.Each component is weighed, then the batch is dumped into the mix chamber (provided the mixer “High level” switch is not covered).

4.The material is mixed in the mix chamber and flows into the processing machine.

5.The optional slide gate below the mixer may control the flow of material to the molding machine or extruder.

Quick Start Procedure

New Recipes

1.Calibrate the weigh hopper before running the blender (This will improve inventory accuracy.). See page 45 for calibration instructions.

2.Ensure that all ingredient supply hoppers to be used are filled with material. Virgin material should be loaded into hopper #1 and regrind into hopper #3.

Note: Hopper #3 on some models is equipped with an oversized square gate to assist in the feeding of the regrind material.

3.Enter the recipe menu on the touch screen by turning on the pendant controller (It will automatically default to this screen), and enter the blend recipe desired following the steps listed below:

a.Touch the box (labeled 1-6) that shows the hopper you want to change.

b.Touch the “Touch Here to CHANGE” button.

c.Enter in the new value (0 to 999.99) and hit the enter button (arrow).

d.Touch “Done”.

e.After you have entered the new values for all hoppers (1-6), then push the “Accept New Recipe” button and the recipe will be entered.
