spherical roller bearing in cement mill 7 that warranted closer evaluation. However, nothing unusual could be seen in a view of the axial vibration at the inboard bearing of the left pinion gear. Two weeks later, additional PeakVue measurements provided the first indication of a serious problem.
•Additional vibration data was collected from the motor gearbox of the 1A Ball Mill Drive under no load. •To determine what problems (if any) existed with the drive, a comparison of the route vibration data between 1A 1B Ball Mills was made as well as between loaded unloaded data at 1A Ball Mill.
The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

kept constant. Typical examples of solid vibration sources are: eccentric loaded rotating machines, panel and machine cover vibration which can radiate sound like a loudspeaker, and impact induced resonant free vibration of a surface. Fluid Noise Air turbulence and vortices generate noise, especially at high air flow velocities ...
Our OK™ Mill grinding solution skilfully comminutes raw material, cement and slag. You can easily adjust it to grind any feed material and produce multiple cement types in the same mill. Due to its highly effective drying performance, the OK™ Mill is the natural choice for grinding blended cements with one or more wet components.
VIBRATION STUDIES OF CEMENT MILL Steps for vibration measurements Impact test was carried out at selected locations on the torsion bar to know its natural frequency Normal vibration signatures were recorded with motor speed being 994 rpm and pinion speed 122 rpm Vibration data was recorded on selected bearing locations of motor, gearbox and ...
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Puzzling Pump Problem Decoded with Motion Amplification. Routine measurements of a pump showed vibration levels of 5 mm/sec at 2X, which is high. We checked for misalignment and soft foot, but. Dean Whittle; Reliability Maintenance Solutions Ltd
Mill Vibration Phenomena during Cold Rolling. All machines vibrate during operation. However, only a few of these vibrations cause problems to the product or the machine itself. Typically, the most damaging vibrations involve a natural resonance of the machine which significantly increases the motion of critical components.
noticed that vibration amplitudes at the same frequencies decrease with increase of load of the mill. Keywords: ball mill, exciting frequencies, vibration signatures, time and frequency domain. 1. INTRODUCTION A ball mill investigated in this study is used for grinding of limestone in a cement .
them, problems of vibration reduction and isolation have engaged engineers. Gradually, as vibration isolation and reduction tech niques have become an integral part of machine design, the need for accurate measurement and analysis of me chanical vibration has grown. This need was largely sa tisfied, for the slow and robust machines of ...
Solving Motor Vibration Problems Vibration problems in induction motors can be extremely frustrating and may lead to greatly reduced reliability. It is imperative, in all operations and manufacturing processes, that down time is avoided or minimized. If a problem does occur the source of the problem is quickly identified and corrected.
