Influence of the type of operating body of knife crushers on energy costs and quality of grinding of plastic waste

Abstract

It is considered the influence of the cutting elements on the quality and energy consumption of processing used PET packaging by cutting. In the course of research, an analytical review of the state of the issue on the basis of modern scientific literature and simulation modeling of the cutting process plastic on machines with working elements of three types: rotor with three knives, rotor with five knives and rotor with saws. It is established that one of the types of cutting element – rotor with five knives, is more rational than others, because it has less load on the working parts and less time is spending on chopping.
