Anti-bridging device - Flat bottom
To boost and control the flow of powders under silo or hopper 

The anti-bridging devices break up lumps and facilitate the flow of bulk materials.
There are flat-bottomed or conical-bottomed anti-bridging devices available depending on the application required.

Manufactured in mild steel, 304 stainless steel and 316L stainless steel
Ø 400, 600, 800 and 1 500 mm

The anti-bridging device with flat bottom is used for the extraction and feeding of pneumatic conveying lines, screw conveyors, rotary airlock valves...  
It provides mechanical agitation of the bulk material to prevent it from caking during storage or after a milling phase.

The anti-bridging device, also called extraction system, is entirely mechanical and is fitted with a rotary blade driven by a gear which moves the bulk material down to the feeding point while avoiding the formation of bridges. Seals on the passage of the shaft are particularly neat with braids and deflector.
Versions with pressurization are possible.
The speed of the anti-bridging device can be adjusted with a frequency converter.
The blade engine is independent (installed power: 1.5 kW - 15 kW IP55).
