ensuring explosion safety in bucket elevators

Apr 30, 2019 History shows a high number of dust explosions originate in bucket elevators and spread into adjacent galleries and silos. The construction and operation of bucket elevators is such that combustible dust clouds and potential ignition sources are omnipresent. In the grain handling industry, the bucket elevator is considered among the most dangerous pieces of equipment
