Definitions for Today
Capacity• Tons per hour –
important, but ….
Net tons per shift/hour is more important
Pellet Quality• PDI - Pellet Durability
Index Standard K-State tumble
method or Holman
It is understood that pellet quality is a broader term than just PDI

What is the normal relationship between Tons per Hour and Pellet Quality?
As Tons per hour increase ……
………..Pellet Quality decreases
(More energy input per ton improves pellet quality)

Current Methods to…
Increase Capacity are:• Increase/improve
conditioning • Formula changes• Die Spec (thickness,
open area, etc.)• Less down time
Improve Pellet Quality are: • Increase/improve
conditioning • Formula Changes• Thicker die• Slow down pellet mill

How can we optimize both Pellet Quality and Net tons/Shift?
Roll SpeedMeasurement(with lineator)

Roll Speed Measurement
![Page 9: Optimizing Pellet Quality and Capacity with new Technology · • Conditioning, formulas, die spec’s, etc. are all major components on optimizing pellet quality and capacity •](https://reader030.vdocuments.mx/reader030/viewer/2022040600/5e89afeef9fe117d732a0368/html5/thumbnails/9.jpg)
Why should we measure Roll Speed?
• Make changes before choke occurs
• See if one roll needs adjustment
• Decrease jog or down time – Increase production time
![Page 10: Optimizing Pellet Quality and Capacity with new Technology · • Conditioning, formulas, die spec’s, etc. are all major components on optimizing pellet quality and capacity •](https://reader030.vdocuments.mx/reader030/viewer/2022040600/5e89afeef9fe117d732a0368/html5/thumbnails/10.jpg)
What can make a roll rotate too slowly or stop
• Increasing conditioning temperatures (moisture)
• Increasing feed rate
• Increasing distance between roll and die

Summary
• Goal is net tons/shift of good quality pellets
• Conditioning, formulas, die spec’s, etc. are all major components on optimizing pellet quality and capacity
• Roll Speed Measurement along with the lineator is another tool to further optimize pellet mill performance and feed mill production
