High performance pulp processing equipment design

纸浆和造纸行业及其相关供应商行业是加拿大最大的净出口行业之一，具有重要的战略意义，目前正面临着能源成本上升、加元高企以及来自低成本南方生产商的竞争的严峻挑战。纸浆筛选机和再碎浆机是木材加工成纸的关键单元操作，加拿大是世界上最大的筛筒和转子生产商之一。本研究旨在开发高性能纸浆筛选和再制浆设备，以支持加拿大纸浆和造纸工业以及这些系统的供应商Advanced Fiber Technologies Inc.。其中一个项目将侧重于通过开发先进的计算设计工具，开发一种经过实验室和中试实验验证的轻质、可靠、高效的筛筒。第二个项目将侧重于了解限制屏幕容量的屏幕致盲机制。通过这种理解，我们将开发具有更大容量的新气缸设计。第三个项目的重点是开发一种高性能的再碎浆机，大大降低了拆浆打包和回收纸浆所需的能源。

The pulp and paper industry and associated supplier industries one of the largest net export, strategically important industries in Canada that is facing extreme challenges from higher energy costs, high Canadian dollar and competition from low cost southern producers. Pulp screens and repulpers are key unit operations in the processing of wood into paper and Canada is one of the largest producers of screen cylinders and rotors in the world. This research is aimed at the development of high performance pulp screening and repulping equipment in support of both the Canadian pulp and paper industry as well as the supplier of these systems, Advanced Fiber Technologies Inc. One project will focus on the development of a lightweight, reliable, highly efficient screen cylinder through the development of advanced computational design tools validated through laboratory and pilot experiments. The second project will focus on understanding the mechanisms of screen blinding that limit the capacity of the screen. Through this understanding we will develop new cylinder designs with increased capacity. The third project focuses on the development of a high performance repulper that significantly reduces the energy required to deflake baled and recycled pulp.
