RE: YeloRoll Idler Test

Duration: November 2001 - May 2002 (6 Months)

To Whom It May Concern

This is to confirm that we have used and tested the "Yeloroll" idler roller since November 2001 in our crushing plant to produce crush stone and silica sand, results were more than satisfactory due to the harsh conveying conditions, dusty, abrasive and corrosive material we found we are getting better life out of the Yeloroll and less bearing failures.

We are slowly replacing our steel & HDPE rollers with "Yeloroll" rollers.

We would recommend "Yeloroll" in any conveying conditions.
