Ball Mill PINION SHAFT BEARINGS. Pinion shaft bearings are of the SKF anti-friction type mounted in a common twin bearing assembly. Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction.

FREQUENCY ANALYSIS OF VIBRATION Vibration measurements were taken on the feed end bearings of the considered ball mill pinions. The dB amplitudes of vibration for all of the velocity spectra are referenced to 8 mm/sec. Figure 3 presents the vibration spectrum of pinion 1A in ball mill 6. Gear mesh frequency and sidebands are marked.

All of our gear units are equipped with unparalleled condition monitoring sensors. Normally, these types of sensors keep an eye on critical operating parameters like bearing temperatures, casing vibrations, etc. and trigger a mill shutdown in the case of exceedances. Our condition monitoring system does much more.

The production process culminates in two ball mills. Each day, the 15-meter-long machines grind up to 5000 metric tons of clinker – the result is ready-to-use Portland cement. In each mill, two pinions and gear units transfer the force from two 2250-kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface.

Ball mills Even though ball mills are gradually being replaced by vertical mills and roller presses, they are still the most common grinding systems in today’s cement plants. The majority of ball mills are driven by Open Gears. Some have central drives or enclosed gear/bearing arrangements.

The gears on the mill on this foundation were very difficult to align and the alignment and vibration of the system was worse when the mill was rotated in one direction rather than the other. We found that the direction of rotation would result in a change in the vibration levels at the pinion piers of up to 7 times depending on the level of
