Solid, Granular & powdered materials have been traditionally managed, by mechanical conveying equipment such as screw conveyers/ belt conveyers/ goods lifts/ bucket elevators etc.

This recent concept is driving the solids airborne, in a fluid form, with the help of air or an inert gas traversing in a closed pipeline. This concept has been seen as very attractive due to a closed pipeline conveying & was gathered up by most industries for the managing of solids pneumatically, over the past three decades.

Relying on the outcome characteristics, air volume & pressures used at the design stage. These parameters classify the systems as either DENSE Phase Pneumatic Conveying System or DILUTE / LEAN Phase Pneumatic Conveying System.

TECHFLOW is one of the frontier manufacturers & Designers of a Lean / Dilute type Positive Conveying System for vacuum conveying. In this system, the material is conveyed with the use of a Centrifugal Blower/Roots Blower/Regenerative Blower. For instance, a powder conveying system employs pressure and vacuum to transport materials as they were liquids horizontally and vertically to and from process devices. Here the material is conveyed either by adverse suction or by the positive force of the blower.
