ONE CASE OF VIBRATION DIAGNOSTICS OF RVM-45 VIBRATION MILLS AT A SINTEZ-PKZH LLC PLANT

Abstract

The article describes the course of vibration measurements at a particular metallurgical plant, one of the workshops of which is equipped with vibration mills, from the formulation of the problem to the analysis of the results. The problem lies in the low quality of the floor on which four RVM-45 vibratory mills of the RVM-45/131.01 design are located, causing periodic loads and vibrations. The paper presents the results of vibration tests obtained through measurements at various points in the room during the startup, operation and shutdown of mills. The studies were carried out using a measuring device “Vibran-2.1”. The reason for the occurrence of progressive vibration caused by the intearactive operation of vibration mills RVM-45 is revealed. Ways to reduce the overall level of vibration in the room with the simultaneous operation of all mechanisms are proposed.
