Ø400, 600, 800 and 1,500 mm

Flat-bottomed anti-bridging unit for extracting and feeding pneumatic transfer systems, screw conveyors, rotary feeders, … Its function is to ensure mechanical mixing for the material in order to prevent caking during storage or after grinding.
The anti-bridging unit is entirely mechanical. Sealing at the shaft passage is particularly meticulous with braids and baffles. Pressurized versions are possible.

Main advantages

  • Mechanical extraction without air or vibration and therefore without pollution or settling
  • Fitting under the silo with a simple flange
  • Works independent of load with full silo emptying
  • Low installed power
  • Sealed, silent operation
  • Easy to install: losose flange, adjustable length, flexible or rigid feeder
  • Quick assembly
  • Easy recovery or transfer module adaptation
  • Independently operating dual feeder
  • Reduced floor space required
  • Limited silo ground clearance
  • Accurate extraction whichever quantity of powder remaining in the silo
