Abstract

The article presents the preliminary results of numerical simulations of the densification process of shredded waste wood. The purpose of the simulation was to evaluate the possibility of using the Drucker-Prager-Cap model in the field of modeling plastic deformation of shredded biomaterials. The experimental studies allowed the verification of numerical simulations. In the research, the stamp-cylinder assembly of a special construction was used, adapted for assembly on a strength machine. The tests carried out are to constitute guidelines for the construction of machinery and devices for compacting biomass.

Summary

Introduction

There is an emphasis on facilitating energy generation from renewable sources. The term biomass refers to all kinds of natural (organic) materials, which can be processed to generate energy. The majority of the biomass is processed before it can be utilized This process usually entails compaction to form pellet or briquette [2,3,4,5,6,7,8]. It calls for utilizing briquetting machines with sufficient efficiency [9, 10]. The possibility to design such a machine depends to a significant degree on the understanding of the compaction process of broken down organic materials which allows to model and analyze it
