Abstract
The topic of this project is pelleting of wood, where the main focus is how the die design affects the pelleting process. The project provides a thorough review of the pelleting process, and presents results of published studies. The project is carried out with experimental work and includes two numerical models. The experiments provides an insight of how the pelleting material behaves when pressed into a die. The project is the first step in order to be able to simulate the pelleting process. A 1D and a 2D model have been set up, in order to simulate the pelleting load for dies with different inlet designs. With the 1D model it is possible to simulate pelleting loads for dies without an inlet. With the 2D model it is possible to perform simulations, that shows the correct tendencies of the pelleting load, when an inlet is added to the die.
