Nov. 3, 2009 – A growing number of specialized biomass applications require short-fiber thin
wood chips. These include the wood
pellet industry, co-firing with coal, and certain gasification processes.
Peterson's 5900 chipper and 5000H model delimber-debarker chipper can
now be readily adapted to produce uniform chips as short as 0.25 inches (6 to 7
mm) and 0.08 inches (2 mm) thick.

Wood chips need to be a consistent thickness for uniform process control in a
digester or dryer. Short fiber
length is especially important if the chips will be further reduced in a
hammermill. If low bark and ash
are a requirement, the Peterson 5000H can achieve less than 1% bark content in
many conditions. The Peterson 4800
stand-alone flail debarker can also be paired with the 5900 disc chipper for
low bark applications.
