Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).

At this time, the vibration frequency of the car is shown as the rated frequency of the motor: N/60*P is the extreme logarithm. Case: Six OH5000 MRL, 630KG, 1.0M/S, the main vibration frequency of the sedan is 19HZ. The amplitude of the frequency …
Case History 1: High Vibrations, Acceptable Forces, Structural Resonance A newly installed boiler feedwater pump was started up and found to have excessive radial vibrations on the bearing housings of the pump (over 0.5 in/sec pk) primarily at vane passing frequency as well as high radial and axial vibrations on the motor at shaft frequency.
A rolling mill 2 of this company uses an 800 HP motor, which is used to transmit the power to the rolling mill. Motor shaft S1 is rested on bearings B1 and B2. It is coupled with smaller pulley shaft S2 with the help of coupling C1. Smaller pulley shaft is placed on bearings B3 and B4.
An Experimental Analysis Of Vibration Of A Ball Mill . citeseerx document details this paper deals with the experimental investigation of vibrations of a ball mill under variable load. the common causes of vibrations of the ball mill are described in short. the exciting frequencies at which the possible causes of vibration can be recognised are estimated for all principle parts of the ball mill.
The Gearless Concept The Gearless Drive avoids any contact between the rotating mill and the static parts of the motor. This enables a contin-uous workflow without maintenance on the gears or the pinions. What used to be downtime is now productive time. Vibration-free, low-weight, short-circuit- proof design with high stiffness

Vibration Severity Chart How To Use This Severity Chart 1) 3-in-1 chart plots vibration measure and levels for: Acceleration vs. CPM, Velocity vs. CPM, and Displacement vs. CPM. 2) Knowing a machine's RPM (i.e. CPM) and the vibration sensing technique (see table below), determine how the …
• Motor behavior during normal operation with a loaded mill The result is the design of a Gearless Mill Drive motor for a 42ft Grinding Mill providing up to 35MW of power. Evolution is still the main GMD design philosophy, but realistic and proven computer models help to look beyond experience, where testing is impossible.
The results show that when modelling the vibration behaviour of a motor structure, the laminated stator should be treated as an orthotropic structure, and the teeth of the stator could be neglected.
