In bachelor thesis We focused on the status and analysis of chipping machines working mechanisms as it comes from the title of the thesis. In the introduction We explained the terms such as biomass or dendromass which are directly related to chipping mechanisms as well as the products created after processing. Next, We focused on utilization of these mechanisms, what their technical paramteres (e.g. performance, weight, etc.) are, their classification, driving mechanisms and construction. The form of my bachelor thesis is theoretical, focused mainly on the comparision of chipping machines available on the market.
