Focus on Your Daily Grind Gear THIS exhaustive round-up of biomass chippers and grinders is a handy “keeper” reference for anyone in, or thinking of getting into this side of the supply chain. It is a mix of information from Timber Harvesting magazine (used with permission) and infor- mation collected by Canadian Biomass magazine, with all information provided by the equipment suppliers. The Acrowoood DEAL Processor provides classifi cation and cleaning as a single step process. ACROWOOD’S REAL DEAL Regardless of the raw fuel source, the Acrowood DEAL Processor is an ideal choice for biomass fuel handling and can be used in either a recovery or main infeed cen- ter format accepting, classifying and cleaning the wood rich diet in a single step. The coarse primary fraction, typically large wood chunks, stumps and logs, stay above the DEAL Processor rotor array where they are cleaned by the abrader tips and the intense tumbling action, while the secondary fl ow fraction is quickly expelled thru the rotor array interface opening to a collection conveyor. The primary fl ow spills over an adjustable discharge gate, goes thru a reduc- tion process, and onto the boiler fuel accepts conveyor. Secondary stream is dependent upon the streamʼs composition. If the material is heavy to mineral, dirt and inorganic, then the stream may be composted to provide a soil supplement, used for landfi ll cover, returned to the forest floor, etc. Where the secondary stream has a high percentage of useable wood fiber with relatively low tramp materials, it can be directed past the chipper or hog and into the boiler accepts conveyor. If the stream has a high percentage of useable fiber but is contaminated with tramp or mineral components, then it can be further refi ned by rotary deck screen- ing and destoning to recover the useable wood fiber component. Only the Acrowood DEAL Processor provides the classification and cleaning as- pect as a single step process. Enhanced by a default metering function to ensure smooth delivery of coarse clean fi bre to down stream processes, these heavy duty units provide long term performance with minimum maintenance requirements. www.acrowood.com The Bandit 3590 is a 750-hp whole-tree chipper introduced in 2007. BANDIT GOES FOR FUEL Anticipating an increase in demand for woody biomass, two years ago Bandit Industries began developing new products to expand its line of fuel wood harvesting machines. The model 3090, a 24 in diameter capacity unit with a large 34 x 30 in opening, has a larger drum, larger chipper opening and a more powerful feed system that includes a drag chain infeed conveyor. With a 630 hp engine, this chipper can fill a 45 ft trailer in less than 20 minutes. Models 3590 and 3590XL, our newest and largest whole tree chippers, were introduced in 2007. The 3590 is a 30 in diameter capacity unit with 700 hp. In CanadianBIOMASS 23
