Techmatic Pneumatic Conveyors

In addition to mechanical conveyors Techmatic is able to offer the full spectrum of pneumatic conveyors that use Air or Nitrogen to transport material down a pipeline. The type of conveyor is selected on the basis of suitability for an application as well as cost-effectiveness both in initial capital layout and running costs.

The conveyors include positive pressure and vacuum conveyors running in lean phase mode as well as positive pressure dense phase conveyors. Lean phase systems (low material to air ratios, conveying pressures below 60kPa) are generally cost effective for lower feed rates and shorter distances (<15 t/hr and up to 150m distance) whereas dense phase conveyors (high material to air ratios, conveying pressures up to 6 bar) become cost effective at higher feed rates and longer distances (> 15 t/hr and distances greater than 150m). The Techmatic dense phase conveying system is currently being used to convey cement powder a distance of 3000m (3km) underground in a Gold Mine.

Where poisonous material is to be conveyed lean phase vacuum conveying ensures that there is no material leakage to atmosphere in the event of bend or pipe wear. Potentially explosive, flammable or hygroscopic materials can be conveyed in closed loop systems running on Nitrogen instead of air as the carrier gas. Specialised application of the pneumatic conveyors are the Techmatic Sorbent Injection Systems.
