Design of the crusher for plastic and rubber waste produced in automotive industry

Abstract

According to European Tyre&Rubber Manufacturers' Association (ETRMA), there are about 1 billion cars all over the world. If the interest in cars does not change, the number of cars is going to be increased and in 2030 there is going to be more than 2 billion cars in the world - regardless of whether they will be powered by a petrol engine or a completely different one at that time. Based on the studies, we focused on the design of the crusher whose task is to effectively recover plastic and rubber waste from used cars. The paper describes the stress - strain analysis of the cutting device of the crusher using a defined material for its production. The basic parameters of the crusher were investigated for a determined final cutting force. Based on the cutting force and the designed crusher, a finite element analysis (FEM) was performed confirming the correctness of the selected material for the production of the crusher for the processing waste materials. The basic parameters of the crusher were observed for determination of the final cutting force.
