Since mechanical conveying systems often reach their limits here and can represent an ignition source in various ways, the focus is on pneumatic conveyor systems.
The so-called vacuum conveying system, offers particular advantages here. The free from ignition source design and construction allows the use with dusts with very low minimum ignition energies (MIE).
A low conveying speed is achieved by the plug conveying. Based on the ignition source-free design, simple additional features also enable use in the gas EX area.
