Industry Trends in Chip Storage and Handling, 2000 Pulping / Process & Product Quality Conference Proceedings
T. McDonald, A. Twaddle--A survey was conducted of US pulp and paper mills to characterize chip pile management trends. The survey was developed by members of the TAPPI Fiber Raw Material Supply Committee and mailed out in December of 1999. There were a total of 80 respondents to the survey. A typical mill was found to maintain one softwood and one hardwood chip pile, with maximum inventory of less than 25,000 green tons each. Chip transport to piles was most often via conveyors and recovery typically using dozers to a pit reclaim. Pile inventory method was dependent on mill size, but tended to be by visual inspection. Conversion of pile volume to weight was predominately through a constant factor of unknown origin. Important losses in chip quality varied by region, with brightness losses being the major concern in the West, fungal and size losses in the North, and by-product losses in the South.
