WEIGH SCALE BLENDER®
MAGUIRE PRODUCTS, INC.
Turning on Material Type Outputs
This controller can control up to TWELVE (12) components; 1 through 9 and A, B, and C.
You must "TURN ON" the COMPONENT outputs that you are going to use. Components that are TURNED OFF are not part
of ANY routines. A component becomes TURNED ON when it is set to a MATERIAL TYPE.
Material Type Definitions
Material TYPES are REGRIND, NATURAL, and ADDITIVE.
The WEIGH SCALE BLENDER handles each TYPE DIFFERENTLY. Settings have different meanings for each TYPE.
To enter SETTINGS correctly, you MUST UNDERSTAND how different materials are handled based on their TYPE.
So PLEASE read this page CAREFULLY.
Material TYPES are explained here.
How to set them is explained on the next page.
REGRIND
(PERCENT OF MIX)
Components designated REGRIND will be added as a PERCENT of the ENTIRE MIX of material. For example, If component
1 is designated as REGRIND and is set for 20.0 percent, then for every 100 pounds of blend, 20 pounds will be this
component.
NATURAL
(RATIO TO EACH OTHER)
Components designated NATURAL will be added in the proportion that you specify them to each other. Their actual
percentage of the mix will depend on how much Regrind is specified and how much Additive is specified. For example, if
components 2 and 3 are both designated NATURAL and are set for 10 and 40 respectively, then the RATIO of component 2 to
component 3 will always be 10 to 40 or 1 to 4.
If no Regrind or Additives are specified, the mix will be:
Component 2, NATURAL, SET= 10, 20.0 percent of mix,
Component 3, NATURAL, SET= 40, 80.0 percent of mix.
The RATIO of 1 to 4 is maintained.
If component 1 is specified as REGRIND at 20 percent, the mix is then
ADDITIVE
Component 1, REGRIND, SET= 20, 20 percent of mix,
Component 2, NATURAL, SET= 10, 16.0 percent of mix,
Component 3, NATURAL, SET= 40, 64.0 percent of mix.
Components 2 and 3 are still held at a 1 to 4 ratio.
(PERCENT OF ALL NATURALS)
Components designated ADDITIVE will be added as a percentage of all the NATURALS added together. For example: If
component 5 is an ADDITIVE at 5 percent, then the above example now looks like this:
Component 1, REGRIND, SET= 20, 20 percent,
Component 2, NATURAL, SET= 10, 15.2 percent,
Component 3, NATURAL, SET= 40, 61.0 percent,
Component 4, ADDITIVE, SET= 05.0, 3.8 percent.
The REGRIND is still 20 percent of the MIX.
The NATURALS are still at a RATIO of 1 to 4, although they have been reduced to make room for the Additive.
The ADDITIVE is 5 percent of the NATURALS added together (5% of 76.2).
WHY do we do it this way? Because this is how most plastic processors think of these components. REGRIND is generally
only added when available, and then as a limited percentage of the entire mix.
NATURALS are generally blended at a RATIO to one another. ADDITIVES are most often only intended to be added to the
entire NATURAL portion of the mix, because regrind generally already contains these additives.
