The Forest Engineering Research Institute of Canada (FERIC) evaluated wood chip recovery and productivity at Weyerhaeuser Company Limited's pulp mill in Prince Albert, Saskatchewan. Frozen and unfrozen hardwood and softwood logs were debarked and shipped over a range of butt diameters and lengths. This report summarizes the chip recovery, quality, and productivity, and provides recommendations on how the operation and chip recovery can be improved.
The Forest Engineering Research Institute of Canada (FERIC) evaluated wood chip recovery, quality, and productivity when ring-debarking and chipping deciduous stems over a range of butt diameters in both unfrozen and frozen conditions in northern Alberta.
FERIC undertook a study in central Alberta to compare debarking and chipping of small-diameter logs at a woodroom chipping operation and at a portable in-woods chipping operation. FERIC evaluated whether chip recovery and quality, and chipping productivity, are affected by changes in stem size, log condition (unfrozen versus frozen), and debarking and chipping method. Net operational costs were also examined.
The Forest Engineering Research Institute of Canada (FERIC) monitored and evaluated an enhanced bucking trial. The recovery of veneer bolts, stud sawlogs, pulpwood, and hog fuel manufactured from measured short logs were compared to those revcovered from enhance-bucked long logs. This report also presents productivity and cost information.
The Forest Engineering Research Institute of Canada (FERIC) undertook a study at a woodroom chipping operation in central Alberta to evaluate the recovery and quality of chips produced from 3.5-m short logs. This report describes the chipping operation, and summarizes the chip recovery and quality, and chipping productivity.
The Forest Engineering Research Institute of Canada (FERIC) evaluated the recovery, quality, and cost of aspen chips produced from an in-woods operation near Peace River, Alberta. The analysis included chips from unfrozen and frozen stems of different butt and top diameters. FERIC also identified factors that would be affected when changing the location of the chipping operation from the woodroom to the harvesting site.
