Misalignment of the girth gear affects every rotary kiln at some point in its life. This is because it is directly related to the kiln shell. Sudden temperature changes on the shell circumference close to the girth gear, eg due to brick lining failure or coating collapse, cause thermal crank at the kiln shell.

Generally, this is an imprint that appears over time and as a result of misalignment of girth gear and pinion meshing. The reason for that kind of mark is a too big value of root clearance or in most cases too little where the teeth hit to the bottom part of meshing also very often causing high vibration.

Similarly, Domazet et al. developed finite element models in order to study the stress distribution and the location of fatigue cracks in cement mill girth gears. Murugan and Ramasamy [23] used statistical methods to analyse power transformer failures with respect to voltage levels, geographical locations and component failures.

The mill is a very important part of the milling process in the cement industry. In many cases, the entire process can be severely limited or completely stopped if the mill ceases to operate and close observation of mill equipment condition is therefore essential. An unplanned stop must be avoided at almost any cost.

The girth gear driving pinion ends up getting aligned to the reduc-er, causing a misalignment issue between the girth gear teeth and the driving pinion teeth (Fig. 1). – Proper alignment should consist of: axial and radial alignment of the girth gear to the center line of kiln/mill; center line of the driving pinion is aligned to the center line

Gears (girth gear and pinions - double drive) are new and from other manufacturer. Compared with the previous gears on this mill, new gears have a larger modulus and different number of the teeth but with the similar gearmesh - now …

The cement mill is driven at 16 rev min"1 by a girth gear fitted to the head wall. The girth gear is driven by two pinions, each being connected via a gear box and coupling to a 1560 kW electric motor. The speed ratio between the pinions and the girth gear is 7:1. The girth gear mounting on the mill shell is shown in Fig. 1.

BALL MILL ALIGNMENT. Ball mills are rotary equipment with relatively high speed of operation commonly used at industry. In fact, due to this higher speed of rotation all the components: pinions, gears, main and auxiliary drives has to be set in a very precise way.

The combined motor to gearbox and gearbox to mill drive pinion misalignments resulted in a loss of end float within the gearbox, trapping the intermediate shaft gear. The 10.3-degree C temperature difference across the mill drive pinion gear was also considered excessive and indicative of severe pinion to girth gear misalignment.
