Most of the significant changes were made to the pocket, knife and knife-holding assembly where the chips are formed and cut and the maintenance and wear costs are incurred.
After substantial design analysis and in-field testing, Morbark has introduced its new Advantage 3 high performance chipping drum, which improves chip-quality in large volume wood chipping equipment and reduces recurring wear-part and maintenance costs approximately 70 percent, to just a fraction of the cost of conventional chipping drums, according to the manufacturer.
Most of the significant changes were made to the pocket, knife and knife-holding assembly where the chips are formed and cut and the maintenance and wear costs are incurred. The new design includes increased clamping force and more durable knives with increased number of possible sharpening occurrences — with extended time and production in between each sharpening. To increase momentum and drum performance, changes also were made to the drum shaft to reduce stress and increase durability.
“Morbark has led the market for whole tree chippers since we introduced the first whole tree chipper in 1969,” said John Foote, Morbark’s vice president of sales and marketing. “Chip quality has increasingly become more important in biomass fuel chips. We have responded with a high performance drum designed for high quality fuel chip that can still fill a chip van in a matter of minutes.”
The Advantage 3 drum is distinguished from other drums in that it creates more uniform chips, reduces operating and maintenance costs and comes with a three year warranty.
The Advantage 3 drum is available on all new Morbark drum chippers and can be ordered as a retrofit to any existing Morbark drum chipper.
