Fluid Channel

Fluid channels are used in silos or bunkers where poor flowing products are stored. A fluid channel is installed slightly inclined, and the extensive aeration ensures an easy discharge of even poor flowing products.


The number of fluid channels to be installed depends on the specific customer requirements; it may vary from single channels in the cone for small containers to the extensive placement of channels covering the whole area of large silos.


When air is fed into the air channel (1), the air evenly penetrates the bulk material over the whole length of the channel by passing through the porous floor (3). The air flushes around each single dust particle. Thus, these air pads eliminate the adhesion of the dust particles among each other, reducing the wall friction in a way that the dust-air mixture is transformed in a liquid-like substance.
