Detecting and preventing bucketelevator failure

摘要

In 2016 a commercial grain elevator in central Ohio USA was unintentionally shut down due to an equipment failure during the grain harvest. The cause of failure could have been easily prevented. The results of the failure were a calamity. The cause ofthe failure was a belt burned in two in a 20,000 BPH [508 MTPH] main receiving elevator. Apparently, the belt started slipping on the elevator head pulley. Friction burned the belt in two, dropping half of the belt and buckets down each side of the elevator casing. The buckets on the up side were all full of grain. The elevator was inside of a jump-formed concrete storage facility.
