Development of a Method for Mechanical Strength Analysis of Pelletizing Machine

Özet

As the sources of fossil fuels are restricted and usage of them is resulted to GHGemission, it is necessary to use renewable energy sources as strong alternative for fossil fuel. Solidbiomass is one of these renewable energy sources in order to produce heat and electric. In orderto use solid biomass energy much more effectively it must be pelletized. Pelletizing is a mass andenergy densification for materials with low bulk density such as sawdust, straw and otherherbaceous energy crops. Pelletizing is a method of increasing the bulk density of biomass bymechanical pressure. The process assists to reduce transportation costs, provides better handlingand feeding of the biomass and efficient storage with less dust formation. In the industrial scale,pelletizing of biomass is done by means of cylindrical pelletizing machines. Generally, thesemachines are manufactured by small scale companies. Samll scale pelletizing machinemanufactures usully have not suffiicant knowlage and staff to run comprehensive mechanicalstrength analyses during machine design process. The objective of this study is to proper a simpleprogram for mechanical strength analysis for main parts of cylindrical pelletizing machines.
