【 摘 要 】

The article considers the problem of processing polymeric waste on roller machines with the possibility of further use as reinforcing elements of composite materials. The aim of the study is to develop a rational design of the device to ensure the qualitative splitting of amorphous-crystalline polymers with minimal energy costs. A mathematical model of the deformation process of polymeric material between the gear rolls is developed, and analytical dependences of the value of the relative deformation of the material compression are obtained depending on the design parameters of the gear rolls. As a result of the research, the optimal values of the diameter of the toothed rolls, the tooth heights and the profile angle of the teeth for the processing of the most common polymeric materials (polyethylene, polyethylene terephthalate, polypropylene) are proposed. The developed recommendations can be used for manufacturing energy-efficient processing equipment.
