Contamination is often a significant contributor to gear tooth failures.

Flushing Process as per ASTM E2905

Bull gear flushing is needed to remove contamination and lubricant buildup on bull gears when contamination is present, particularly when slurry enters the gear guard.

Removing built-up contaminated lubricant, allowing for an accurate visual inspection as per AGMA 1010-F14 and to ensure an accurate Eddy Current Array scan in accordance with ASTM E2905.

Wiping and/or rinsing gear teeth not required for this process.

Girth Gear Cleaning/Flushing – Mill and Kiln Girth Gear Drives

Global’s Bull Gear Cleaning Programs are designed to remove contamination and lubricant buildup on bull gears and pinions prior to inspection. This is accomplished by flushing the bull gear while in production, which minimizes downtime. The actual time of flushing a gear set is under two hours. There is no need to wipe the gear teeth down or rinse after, to remove residue as required for Magnetic Particle or Dye Penetrant inspections, if using the Global Process™ inspection method.

Provides the ability to perform visual interpretation (AGMA 1010-F14); of the failure modes present, if any, their severity, and how these might impact the operational function of the mill

Clear or translucent lubricants still require cleaning to conduct a thorough visual inspection, as the lubricant can obstruct critical details on the tooth surface.

Procedures that used to take days can now be completed in less than two hours. Using this procedure, gears are safe from damage due to the specifically formulated CLEANSOLV Products.
