The fact is, most materials can be conveyed using any of several methods. No one can say with certainty, for example, that positive pressure pneumatic conveying is always the better choice for conveying high-temperature materials, or that a tubular cable conveyor is the only option for handling fragile or friable material.

The most significant difference between the two solids-conveying systems is the presence, or absence, of motion in the plane normal (perpendicular) to the plane of the conveying surface. Angular-pitch vibrating conveyor In its simplest form, the angular-pitch vibrating conveyor consists of a trough with a mechanism to oscillate it.

An in-between option is semi-dense-phase conveying, which uses a medium-velocity airstream in which part of the material is suspended. It's suitable for abrasive or friable materials. Another basic distinction with pneumatic conveyors is how product will be propelled: pushed with positive pressure at or near the intake point, or pulled by a ...
