Quantitative indicators of economic reliability analysis press-granulator with a fixed matrix

Purpose. Determine the main quantitative indicators for the economic analysis of the reliability of the pellet mill with a fixed matrix. Methods. Methods of grouping, system analysis, synthesis, scientific generalizations and the method of argumentation were used. Results. It is indicated that the main quantitative indicators for the economic analysis of machine reliability are: the cost of measures to increase reliability, the economic effect of increasing reliability and the payback period of measures to increase reliability. Equations are given for determining the payback period of measures to increase reliability and operating costs with increasing reliability. The conditions of economic feasibility of work to increase the level of reliability are determined. Conclusions. The calculations show that the annual economic effect of increasing the reliability of the pelletizer is 175.82 thousand UAH/year. Reliability enhancement measures reduce operating costs by 18.7% and payback periods are 2.55 years. Keywords: livestock, pellet press, reliability, efficient use, economic feasibility.
