The professional handling of dusts and powdery solids requires a comprehensive consideration of the task. In addition to the purely technical questions relating to feasibility and implementation, numerous boundary conditions must be taken into account.
One of them is the possible use in potentially explosive areas. The crux here is that these areas can not only be predefined from the outside, but potentially only arise through the actual conveying task or the conveyed goods themselves.
This is due to the fact that every substance which is flammable, in either a powdery or dusty form with fine particulates of less than 500 µm, also has the capability for a dust explosion.
Conventional, mechanical conveyor systems often reach their limits of use. Pneumatic vacuum conveying systems, on the other hand, can be designed without ignition sources and are therefore particularly suitable for such purposes. Both for organic compounds and for inorganic substances such as metal powders.
As an extract from the “ATEX, Explosion Protection and Powder Handling” seminars that take place several times a year, this short video gives an initial insight into this extremely complex topic.
