In order to decrease or eliminate environmental contaminants from fluent particulate matter that is removed from bulk material carriers by conventional vacuum conveyor systems, the bulk material carrier is moved into an enclosure which can be closed off from the environment after the carrier is within the enclosure. Clean air containing a prescribed maximum number of particles above a given size floods the entire enclosure and air of even greater cleanliness is fed to a selected discharge valve of the material carrier to entrain the particulate matter in the clean air streams which pass through the bulk material under the influence of the vacuum conveyor.

Clean air bulk material handling method and system

An aerial cable spacer and support fabricated from separate arm members and braces which are selectively joined to form an open frame device which can be hung from a messenger wire. The inclusion of a plurality of fins at acute angles to the arm members and braces increases the leakage distance between cable phases and with ground while facilitating the washing of the fin surfaces and that between the fins while preventing the build up of water on those surfaces. Different lengths of arm members and braces can be fabricated with the same tooling permitting components to be sized according to the voltage ratings of the cable system.

Aerial cable spacer

In order to decrease or eliminate environmental contaminants which are added to fluent particulate matter removed from bulk material carriers by vacuum conveyor systems, the bulk material carrier is moved into an enclosure which can be closed off from the environment after the carrier is within the enclosure. Clean air containing a prescribed maximum number of particles above a given size floods the entire enclosure and air of even greater cleanliness is fed to each hatch of the material carrier to entrain the particulate matter in the clean air streams which pass though the bulk material under the influence of the vacuum conveyor.
