Bachelor Assignment

One of the projects of the Professorship Polymer Engineering at the University of Applied Science Windesheim, is research into the recycling of passenger car tire rubber into a high-quality material. The aim of the thesis is to map the current devulcanization process which has a capacity of 2 kg per hour. And to develop scenarios of possible process setups that will be able to process 20-30 kg of rubber per hour. The final design is an automated process which consists of the following machines (in order): three dosing technologies, an automated tumble mixer, another dosing technology, a twin-screw extruder, a cooling calender, a single-screw extruder with a gear pump and strainer, other dosing technologies, a twin-screw extruder with sheeting die, transportation devices between the machines and finally an air extraction and filter unit with extraction hoods above the two twin-screw extruders.
