Ball Mill Sole Plate. This crown should be between .002″ and . 003″, per foot of length of sole plate. For example, if the sole plate is about 8′ long, the crown should be between .016″ and .024″. Ball Mill Sole Plate. After all shimming is completed, the sole plate and bases should be grouted in position.
Cleaning of gear ring and mill flange → positioning of gear ring → coarse alignment of large gear ring → positioning and coarse alignment of pinion → installation of motor reducer → primary grouting → fine alignment of large gear ring → fine alignment of pinion → fine alignment of motor reducer.
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. Mutual, correct positioning of such elements guarantees their durable and long ...

It is a systematic approach to walk well as various services covering ball mill During a measurement campaign, high by inspection. In Figure 1 a maintenance mechanics (crack test, accompanying ovality and relative movement at tyre 2 inspector checks the gap between the assembly supervision and commissioning was detected.
The first step in girth gear alignment is preparation. The equipment must be shut down and deenergized, and safety protocols should be followed. Once safety measures are in place, the equipment should be cleaned, and any debris or dirt removed. The second step is measuring the alignment of the girth gear and pinion.

mills and ball mills for use in the mining and cement industries. By current standards, girth gears can be as large as 14 meters (46 feet) in diameter, meters (44 inches) face width, and 50 module (.5 DP) tooth size, and weighing upwards of 120 tons. Flange mounted gears rely, in large part, on the mill structure to provide the stiffness ...
There are three ways to align the pinion skew to the girth gear; 1) Using the pitch lines 2) Setting root clearance 3) Setting backlash (only applicable to a new gear and pinion). Measuring the root clearance is best done using Babbitt or lead slugs. Use % 1" diameter Babbitt slugs about 1 to 2" in length.
2. Remove the rotary kiln girth gear. When one of the semicircle gears of rotary kiln rotates to the top, remove the pinion to separate the girth gear from the drive system, and remove the bolts after making marks. Then use the winch to rotate kiln body, remove the other half girth gear. At the same time, make sure to prevent spring plate from ...
