A Brief Tutorial On Machine Vibration

A brief tutorial on machine vibration by victor wowk, p.E.Machine dynamics, inc.The purpose of this tutorial is to provide sufficient knowledge to understand machine vibration diagnosis.You may be tasked with solving a vibration problem, or you may be overseeing someone else and you need to understand the process.

Vibration switches and transmitters are 4-20ma low cost and gives you 247 protection, measuring, trending, alarm, trip settings, time delays and can operate via wifi or installation of vibration transmitters from critical machines to control room panel meters up to 1000 ft away.

Ball level inside the mill.The load level and composition by percentage volume of total mill volume may be determined through the use of mill noise see figure 14, process data and software based on appropriate algorithms.This method of determining mill load composition, together with the software developed, has.

Automated Sag Mill Speed Control Using On Contact

Off of multiple bearing pressure load cells on each mill.Speed control was initially desired to be controlled via a primary variable from a sound measuring system consisting of an array of microphones designed to measure noise and ball impact.However the microphone array based system was abandoned for the following reasons 1.

A ball mill, which is used to finely grind materials, causes high levels of vibration and sound during grinding operations.The vibration and sound of mills provide significant information about the internal conditions and can be used to estimate the status of the ground material.
