Mechanical Belt Fasteners Increase Conveyor Availability

In mining operations, conveyors hold one of the most important keys to productivity. Sudden belt or belt-splice failures and extended repair downtimes can contribute to low material-handling system availability. Consequently, operations and maintenance personnel should have a thorough understanding of the available splicing and repair alternatives and how each method can affect the productivity and cost-effectiveness of their operation. The two primary methods of joining belt ends - vulcanization and mechanical fastening - affect the likelihood of sudden failure and repair times in different ways. The time-honored method of vulcanization remains popular in many conveyor-intensive underground and above-ground mining operations around the world. At first, vulcanization may seem attractive because, when done properly by trained and experienced craftsmen, it can match the original belting fairly closely and give the splice a smooth, continuous surface with no edges or seams to invite snagging.
