CPS Solves Client’s Roller Corrosion and Performance Issues
Posted at March 16, 2023
An important client in Southern Perú contacted CPS to evaluate rollers at their new oxide plant, where sulfuric acid and seawater is used in processing. These highly corrosive elements caused various failures on frames and rollers along the length of the conveyor, leading to wider operational issues.
CPS proposed using Yeloroll-HD for the client’s conveyor ‘vee-return’ areas, where all polymer and steel idlers to date has been failing. The Yeloroll-HD Roller’s heavy-duty, fibre-reinforced, high-density polyethylene shell features increased strength, stiffness, creep resistance, dimensional stability and three times the abrasion resistance of other polymer shell rollers on the market—delivering increased roller life and increased productivity due to fewer roller change-outs and overall downtime.
The CPS team also recommended the CPS Premium Polyurethane Disc Rollers for the flat return idlers located near the head end of the pulley. These rollers are an excellent alternative to plain steel and rubber disc flat or vee-return rollers in critical high-wear areas, such as the head and tail end.
Since re-installation, the CPS YelorollHD and Polyurethane Disc Rollers have been successfully operating, with limited corrosion and no change-outs for over six months—representing a 12x improvement in roller life.
