A growing number of specialized biomass applications require short fiber thin wood micro chips. These include the wood pellet industry, co-milling with coal, and certain gasifica­tion processes. Peterson's popular 5900 chipper and 5000H delimber, debarker, chipper can now be readily adapted to produce uniform chips as short as 0.25 inches (6-7 mm) and 0.08 inches (2 mm) thick. If low bark and ash are a requirement, the Peterson 5000H can achieve less than 1% bark content in many conditions. The Peterson 4800E debarker can also be paired with the 5900 disc chipper for low bark applications.
