About our grinding field crew and method:

Each member of our grinding field crew has undergone specialized training and is internally certified to grind on your equipment. We perform a before and after measurement utilizing TomTom-Tools Measuring Wheel. We grind to a (1mm) tolerance, while tracking hardness to ensure your tires and support rollers are staying within specification.

At the end of the job our customer receives a completion report covering the accumulated data and important facts as well as follow-up items and good maintenance tips.

What we need to know for grinding your rotary kiln or dryer:

  • Can your plant supply power and air?
  • RPM of rotary unit?
  • Type of lubricant used?
  • Face width of tire?
  • What is access like around the unit?
  • What type of drive system?

Helpful Tips:

  • If you see light washboarding, check thrust load on piers OR check gear/pinion mesh.
  • Pitting does not necessarily indicate a need to grind. Contact us to help determine whether resurfacing is appropriate.
