Three Pneumatic Metal Chip Conveying Options


For over 50 years National Conveyors Co., Inc. has been the leader in pneumatic metal chip processing technology, offering three types of systems:
  • Dilute phase VACUUM PNEUMATIC metal chip collection & conveying systems
  • Dilute phase PRESSURE PNEUMATIC metal chip handling systems
  • DENSE PHASE metal chip conveying systems
Each design can handle all types of metal chips (wet and dry) and has its own benefits for a particular application. National engineers can assist with the most effective selection to suit your requirements.

pneumatic chip conveyingVacuum Pneumatic Metal Chip Collection & Conveying

Metal chips are sequentially collected from multiple collection points, such as machine tools, by a vacuum pneumatic conveying system which transports them through pipelines to a central receiving station where they are separated from the induced air flow and discharged into a disposal container storage bin or automatic loadout system. The conveying air flow generated by a mechanical exhauster is filtered prior to discharge into the atmosphere.

Metal chips (from chip wringing operations or other sources) are dumped into a receiving hopper from which they are fed into a pipeline where air flow generated by a pressure blower unit carries the material downstream to a target box where flow velocity is dissipated, allowing chips to discharge by gravity into a container or truck.

Dense phase pneumatic conveying systems offer the advantage of being able to convey either wet or dry chips with equal effectiveness. Chips from machining operations, filtration systems or other sources are stored in a surge hopper from which they are fed in batches of controlled volume and pneumatically conveyed to a discharge point.
