Abstract
Abstract Successful development of road-construction machinery requires continuous improvement of existing and the introduction of new materials in the production of machine parts. The production of machine parts from polymer composite materials based on various types of binders containing dispersed and fibrous fillers is of a great interest to researchers. Polymeric composite materials consist of two or more components that differ in chemical composition, physical and mechanical characteristics. The main purpose of the filler is reinforcement, i.e. hardening of the material and imparting the required special properties, for example containing fibrous fillers. We took natural flax as fibrous filler in experimental studies. The paper attempts to study the intensity and quality of the grinding technological process depending on the time and frequency of rotation of the mechanism, the factors that influence it, the relationships and the laws of the technological grinding process in drum-type mixers, and increasing the efficiency of grinding material, reducing dynamic stresses.
