UNDERGROUND DUST AND ABRASION
Case study
Mining
Copper
Chile
Challenge
Improve performance and extend the service life of the rollers installed on level 1 conveyor (underground), exposed to an extremely dusty environment that accelerates wear and causes premature failures in the bearing and sealing system.
ULMA solution
Installation of ULMA RM-178x6x1000/6310 return metal rollers, featuring a patented sealing system, manufactured with high-quality components and assembled under the strictest standards to ensure maximum durability in environments with high dust concentration.
Field monitoring over more than seven months of continuous operation confirmed stable performance in terms of temperature, noise and appearance, with no bearing failures or loss of sealing.
Key learning
Tripling durability compared to previous rollers, reducing maintenance requirements and ensuring stable operation in a highly abrasive underground environment.
