High performance pulp processing equipment design

纸浆和造纸行业及相关供应商行业是加拿大最大的净出口和具有战略重要性的行业之一，正面临着能源成本上升、加元升值和来自低成本南方生产商的竞争的极端挑战。纸浆筛网和碎浆机是将木材加工成纸的关键设备，加拿大是世界上最大的筛筒和转子生产国之一。这项研究旨在开发高性能的纸浆筛分和再碎浆设备，以支持加拿大纸浆和造纸工业以及这些系统的供应商高级纤维技术公司。其中一个项目将专注于通过开发经过实验室和中试实验验证的先进计算设计工具来开发轻便、可靠、高效的筛分滚筒。第二个项目将侧重于了解限制屏幕容量的屏幕失明机制。通过这一理解，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碎浆机，它可以显著降低打包和回收纸浆的能耗。

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.
