Grinding and Resurfacing

Over time, rotary kilns and dryers experience wear and tear on critical components such as tires and trunnion rollers (carry rollers). This wear can lead to uneven surfaces, causing vibration, misalignment, chattering, and reduced efficiency. If left unaddressed, the damage can extend beyond the tires and trunnions, affecting bearings, piers, thrust rollers, and even the gear and pinion system—resulting in costly repairs and extended downtime.

At O’Connor Kiln & Dryer, Inc., we specialize in precision grinding and resurfacing to restore these essential components to their optimal condition. Our state-of-the-art grinding machines—designed and built in-house—are capable of resurfacing tires and trunnions ranging from 2 to 60+ inches wide.

Benefits of Grinding and Resurfacing:

• Eliminates surface irregularities that cause mechanical stress
• Restores proper contact between tires and trunnion rollers
• Reduces vibration and mechanical wear
• Extends the lifespan of bearings, thrust rollers, and drive components
• Enhances overall efficiency and reliability of rotary equipment
• Our on-site grinding capabilities allow us to perform these services while your drum remains in operation, minimizing production downtime and ensuring continuous performance.
