Water addition after hammermill

  • Add water so it can soak
  • Create homogeneous moisture in each particle, especially after dryer
  • Controlled flow from hammermill
  • Conditioner model LL or LT for larger capacities

6

Moisture measured at inlet of ripening bin with online moisture analyzer

7

Stable moisture for stable process conditions

  • Optimizes pellet quality
  • Minimizes energy usage
  • Provides longer die and roller life

Ripening at retention vessel

Mixing bin or vertical bin:

•  Variations in moisture

•  Variations in product type

8

Vertical bin:

  • First in first out
  • Larger volume, longer retention time

Mixing bin:

  • Homogenizes the raw material
  • Limited retention time
