So it is a large synchronous motor coupled to a stub shaftcoupled to the pinon and it meshes with the bullgear that is on the outer circumference of the mill. Pinion speed is indeed 180. Bull gear tooth count is 241. I had a cage failure on one of the pinion bearing 2 years agoat that time
Very low frequency vibration normally comes from process control systems and is better analyzed using the mill DCS or a process database such as PI or Aspen. One other vibration analysis technique for identifying the root cause of the vibration is called synchronous time averaging (STA).
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis Advantages of Ball Mills 1 It produces very fine powder particle
Sep 102012 The mathematical analysis is validated with experimental data comparing the vibration signature of helicopter transmissions operating either normally or with damageleading to shifts in the planet gear positions. Time Synchronous Averaging of Ball Mill Vibrations, Effects of Time-Synchronous Averaging Implementations on HUMS
This article discusses an example of an outer race-bearing defect on a 1,250-ton (4,400-kilowatt) air-conditioning chiller. The defect was detected using off-the-shelf portable vibration analysis hardware and software. The machine is a single-stage centrifugal compressor with a rolling element
at any time over the whole speed and load ranges. This means that the synchronous machineas seen from the speed control systembehaves like a DC machine. The TRANSVEKTOR control used on high-power mill drives has gone through a long development phaseand during the last 33 yearsa lot of experience has been gained.
