ASGCO® Tru-Trainer® Dual Return Urethane Idlers Save the Day at This Copper Mine

Challenge: The challenge involved an extreme incline conveyor belt 96” wide, with tandem drives
and a 6 pulley take-up system.  Due to the nature of this Drive system design, along with the
speed of the belt and together with the high tonnage that this system see’s during each shift,
severe belt mis-alignment was a serious problem. The conveyor belt had tracking problems on the
return side of the conveyor, especially through the 6 pulley take-up system. This was exaggerated
because of the incline and belt speed of this system.

Solution: ASGCO® recommended that two Tru-Trainer®  Dual Return Urethane Idlers (96”) solutions_january_2017_application-pic_web
be installed before and after the counter weight systems, while leaving the 6 series deflector pulleys
in the loop take-up system so they would be calibrated. The current trainer was an 84” modified
unit brought over from another conveyor system. The Tru-Trainer® Dual Return Urethane Idlers
being installed would simplify the installation process and improve the tracking conditions in
that section. This would center the belt before those critical areas, avoiding the possible loss
of material due to belt mis-tracking on this long high speed, high tonnage conveyor belt system.

Results: The damages to the belt since the installation of the Tru-Trainer®  Dual Return Urethane
Idlers have been completely eliminated.  There was also a significant improvement in the overall
production average for the month following the installation. Due to the excellent performance
of the Tru-Trainer® Dual Return Urethane Idlers, the customer is purchasing several additional
units as a new preventative maintenance implementation.
