Cement Processing

Girth gears, pinions, and kiln drives for cement plants that run around the clock in abrasive conditions.

Built for cement processing

Cement processing puts gearing under relentless load, heat, and dust. We manufacture large girth gears, drive pinions, and complete gearing for rotary kilns, ball mills, and crushers — built in segments for the largest diameters and engineered to survive continuous duty in the harshest plant environments.

Challenges we solve

  • Continuous heavy load on kiln and mill drives
  • Large girth gears assembled from segments
  • Abrasive, high-dust operating environments
  • Fast replacement to minimize plant downtime
