Vacuum conveyors built for explosive applications

| By Chemical Engineering



The risk of explosion due to dust is a major operational concern in many industry sectors. To address this, the E-Line vacuum conveyor (photo) is designed to be fitted with either an explosion-venting or explosion-suppression system, based on application requirements. The National Fire Protection Association (NFPA) has been creating stricter guidelines for manufacturers’ processes, and source machinery that is explosion diffusing is becoming a necessity for compliance. In order for an explosion-diffusing system to function properly, the conveyor canister must be able to contain a certain level of pressure (up to 14.5 psi) before the system activates. With the ability to add explosion venting or suppression, the E-Line provides an alternative solution to purging material-handling systems with nitrogen, which can be a costly process. — Hapman, Kalamazoo, Mich.
