Fluidisation Pads

Bridge building is a problem in silos that often occurs.
It is a problem in which the remaining material in the silos starts to form a 'bridge' on the sides of the silo. This bridge formation obstructs further outflow of the material in the silo. An additional disadvantage of the 'bridge' formation is that it could damage the rest of the circuit.

The answer to this problem is simple: fluidisation pads.
By applying the fluidisation pads into the sides of the silo, the pads can aerate the silo. This aeration prevents cohesion of the particles from the material inside the silo. The cohesion of the particles causes the bridge formation to begin.
Thanks to the aeration of the fluidisation pads, bridge building can be prevented and the content of the silo can flow down smoothly.


By drilling a hole in the silo wall, a fluidisation pad can be placed inside the silo. In highly stressed structures, it is sometimes necessary to weld a reinforcing ring round the hole.
Once the fluidisation pad is placed inside the silo, it is attached with a seal, a washer and a nut.
The last step in the installation process is connecting the fluidisation pad to a closed-circuit line, which provides the air for the fluidisation pad.

How it works

Air is blown through the fluidisation pad into the silo by the closed circuit line. The air which is blown into the material reduces the cohesion of the particles from the material. This reduce of cohesion prevents bridge building, an obstructing process in the silo. The fluidisation pads also ensure that all the material inside the silo can easily be transported to the outside.
