Scientific and Practical Ways of Increasing Operational Reliability and Productivity of Small Grain Grinders

Abstract

Seven different types of grain grinders were tested under production conditions. Grain grinders with vertical and horizontal cutting organs were selected for investment in mass and feed production. Their technical, economic parameters, and operational reliability were investigated. Based on the statistical evaluation of the operational reliability of grain grinders, the average statistical values of their readiness factor were calculated, which was Kp=0.8 for UHM-2.2, and 0.51 for HHUM-2.2. Meanwhile, it is established that the readiness factor of the machines and equipment used in animal husbandry and feed production should be no less than 0.94. All defects of nodes and machine parts were identified, also scientific and practical recommendations were made to eliminate and improve operational reliability. It has been established that in the case of identifying defects arising during the long-term operation of these grain grinders, eliminating them with appropriate methods, and finally improving their structure and function, it is possible to successfully organize their mass production and implementation in agriculture, particularly feed production.
