Bandit Produces Bio-Sawdust

Bandit Industries, Inc. has developed technology that allows a ¼ in. minus sawdust-type material, known as bio-sawdust, to be produced from debarked roundwood in a single pass. Benefits of this new system include greater fuel efficiency, higher production levels in pellet mills, and the potential for expansion into biofuel and bioelectricity production, according to the company.

Because the process used to produce bio-sawdust is a cutting action, far less energy is consumed in producing the fine material. When using a diesel-powered Beast, up to three tons of material can be produced per gallon of diesel fuel consumed.

Additionally, the wood fibers are cut, not fractured. Pellet operations report that this type of material packs much more efficiently into the pellet dies, yielding greater production. Pellet operations in British Columbia receiving material from the Beast are reporting a 10% to 12% increase in production at the pellet mills when running material from the Beast.

The cutterbody is shaped like a sawtooth on a chain saw, which enables the chipping system to make a precise, regulated cut. The material entering the Beast is also controlled by the infeed system, which forwards material to the cutting system at the exact speed required to produce the desired chip length. When producing bio-sawdust, the chipping operation generally yields better than 95% acceptable material (¼ in,-minus) in one pass.
