vibration measurement at vertical mill

Vibration measurement, proximity probes. Instrumentation

Sep 06, 2020· The scale factor for proximity sensors is set at 200 mV/mill or 7.87 mV/micron (mV is peak to peak). For example: As per the table below, The Voltage at 40 mills (1.01 mm) is -7.49 V . The voltage at 50 mills (1.27 mm) is -9.48 V . Gap is 50 mill 40 mills = 10 mills. Scale factor = Change in voltage/ Change in gap

Vibration Measurement an overview ScienceDirect Topics

Meherwan P. Boyce, in Gas Turbine Engineering Handbook (Fourth Edition), 2012. Vibration Measurements. Vibration measurements as part of a performance test should be measuring the pk-pk amplitude at the bearings, and with the use of accelerometers mounted on the casing of the gas turbine, the forces generated by the entire rotor system. It is recommended that a minimum of two

Chatter in Machining: Milling & Lathe Vibration [ Easy Guide ]

Aug 20, 2019· A vibration in the tool leads to a wave in the workpiece, constant vibration creates a steady series of these waves. Now imagine what happens if you make a second pass over a surface that is already wavy from chatter–the forces on your cutter vary with the peaks and troughs of the waves.

Cause Analysis of Vibration of ATOX 50 Vertical Mill

In general, the ATOX50 vertical mill mainframe is 3500kw, because the material grindability of our factory is poor, and when it becomes worse, the ability of the vertical mill will be reduced and can only be forced to reduce the material operation, otherwise it will cause the vibration of the vertical mill

Causes And Treatment Of Vertical Mill Vibration

The material buffering capacity between the grinding disc and the grinding roller is insufficient, and it is easy to produce vibration. During the trial production of vertical mills, due to mechanical requirements requiring 70% feed, the feed is too small, which is one of the reasons for the large vibration of the vertical mill
