Contamination is often a significant contributor to gear tooth failures.

Flushing Process as per ASTM E2905

  • Girth gear flushing is needed to remove contamination and lubricant buildup on mill girth gears when contamination is present, particularly when liner bolts fail, and slurry enters the gear guard
  • Flushing prior to inspection is necessary to enable a proper ASTM E2905 and visual inspection in accordance with AGMA 1010

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

The GEARSOLV EP Open Girth Gear Cleaning Lines formulations are designed to remove contamination and lubricant buildup on girth gears and pinions prior to inspection. This is accomplished by flushing the girth gear while in production, which minimizes downtime. The actual time of flushing a gear set is under an hour. 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.

Gear Engineers use visual interpretation (AGMA 1010-F14) to analyze the gear teeth condition, such as contact patterns and wear patterns; hence, a clean gear set is a must. 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 an hour. Using this procedure, gears are safe from damage due to the specifically formulated GEARSOLV EP Products.

As a result, gears are fully cleaned and ready for inspection faster than ever before.
