Failure Analysis

Belt conveyors play an important role in the transportation of bulk materials. They are used extensively during mining, processing, storage, transportation and, finally, in the generation of power. Because a conveyor delivers a very small amount of material over long periods of time, it is essential they operate efficiently with maximum availability and minimum downtime. Unlike a truck or train that delivers large loads intermittently, a conveyor must deliver a small, steady stream of material continually.

Belt problems might include miss-tracking, accelerated cover wear, carcass failures or the problematic splice failures.

Pulley problems might include shaft failures, end disk or rim breaks, locking device failure or lagging wear.

Idlers problems might include shell wear or bearing failures.

Transfer chutes might include plugging, dust generation, material spillage or accelerated belt wear.

General system problems include starting and stopping control algorithms, brakes, take-up travel, excessive belt sag and drive slip.
