DynaYield II Chip Conditioners by Jeffrey Rader Brand

DynaYield™ Chip Conditioners are designed to gently fissure over-thick wood chips with the least fines and pins generation of any thickness reduction machine.


Chip Conditioners are commonly used in chemical pulping processes and the thermo-mechanical pulping process (TMP). The DynaYield Chip Conditioner primarily consists of two rolls with specially-designed, textured stainless steel segments providing the surface for conditioning, fissuring and treating the oversized and over-thick wood chips.

Advantages and Benefits:

  • With normal oversize wood, the conditioner typically generates less than 1% fines and 3% pins, versus Chip Slicers generating between 2%-8% fines and up to 15% pins
  • Reduced maintenance costs
  • Due to reduction in wear parts in contact with material and due to low speed action of the conditioning process, the wear is significantly less than in other forms of overs processing
  • Centralized lubrication
  • Temperature control in hot and cold ambient environments
  • Easy access for segment maintenance
  • No knives to change; no wear bars to rotate; no gauge plates to adjust and replace
  • Can handle small portions of tramp without going offline
Technical Data
  • 90-degree segments are held in place with special Grade-8 fasteners
  • Driven by an AGMA Class II shaft-mounted reducer
  • All control enclosures are NEMA 4 to provide all-weather protection
