How to Reduce the Effect of Vibration in Production Grinding

01-09-2018  The vibration amplitude at the second set of conditions was measured at 8 microinches versus 79 microinches when grinding at first set of conditions. Again, the imbalance remained the same. But grinding at conditions consistent with contact-length filtering produced a smooth surface despite the imbalance, without any reduction in productivity.

What Are "Beat" Frequencies - Vibration School

Beat vibrations are caused by vibrations that have very close to the same period and similar amplitudes. The animation shown here shows two separate sine waves - the red 1x rpm component of a 2-pole motor and the line frequency being supplied to that motor.

High vibrations on a ball mill AMP Maintenance Forums

21-01-2011  Now, when the mill is started, vibration values are around 14 mm/s, first 4 harmonics of the GM, and then for about half an hour they go up to 28 mm/s (again 4 harmonics of GM) - in horizontal direction while in the vertical and axial direction there is no such change.

Ore Dilution Recovery in Mining

Some dilution almost always occurs in shrinkage stoping, either because of overbreaking the walls of the vein during mining or later sloughing, especially during final drawing. Overbreaking is almost unavoidable when the vein is irregular in strike and dip and especially so if there are numerous small offsets.

Roping HydroCyclone -Bad Operation

HydroCyclone Roping – Incorrect Cyclone Operation is often caused by too high a volume feeding into the cyclone. If the apex capacity is exceeded a condition known as roping may occur. Normally, the underflow sprays out of the apex. When roping occurs, the air core inside the apex collapses and the spiraling motion is almost lost.
