Massive Roller Change Out at Holnam

Clarksville, Missouri

Crews from Phillips' Mississippi Valley Repair Department and Alignment Technician Mike Daily recently completed a change out of a trunion roller on pier 2 at Holnam's Clarksville, Missouri, Cement Plant.

The unit is the largest operating kiln in the world, and is 25' in diameter and 760' long. The rollers supporting the kiln are equally mammoth in size.

The new roller is 114 inches in diameter, 55 inches wide with a shaft that measures 8 feet in length and is 32 1/2 inches in diameter. The new roller weighs 147,300 pounds, not including the bearings!

Phillips Kiln Services responded quickly to move in and change out the roller when it was discovered to be damaged less than a week from the scheduled shutdown.

Holnam representative Fred Bridwell and Plant Manager David Dorris were pleased with the quick response and excellent work performed by our crews, which were headed by Richard Eubanks and Brad Parker, and included Sam Parkhill, James Miller, Dave Miller, Jonathan and Jamie Eldridge, Bill Atteberry, James Wiggins, Ron Litton and James Robinson.
