Today, mechanical engineering is one of the dynamically developing sectors of the economy of Kazakhstan. Any production process involving machines imposes requirements for reliability and durability to ensure stable and trouble-free operation of technological processes. In this regard, ensuring the operational characteristics of machines for a long time is a key factor when choosing a manufacturer. The quality of the materials used in the production of machines significantly affects the service life and operational characteristics of machines. The wear of machine parts is one of the main causes of breakdowns and accidents. The financial costs of car repair items are quite large. To date, the wear control of the mixer elements, removable elements of the blades is carried out only visually and replacement occurs without a system, after complete abrasion or breakage. Since these elements are not always available in the warehouse of the enterprise, downtime of equipment can take a considerable time. Modeling of the wear process of mixer elements in the matlab program allowed us to develop a simulation model using the vibroacoustic control method. Analysis and processing of vibration signals is carried out using standard programs. The developed algorithm of the process of monitoring the wear of the mixer elements allows you to form a library of signals and noises, comparing them with the reference values of the signals, to determine the degree of wear of the mixer elements. The algorithm can be implemented on standard hardware and software devices. Keywords: Mixer, wear, model, control, matlab, management.
