Silo dryer

Introduced and disseminated as a technology in Germany in 1996 by the company Wellenbrock

Silo set circulation dryer / at the same time wet cell; Dryer; Storage silo and transfer cell with a capacity of 100 to 1,000 t

We are supplying our new stirrers into your silo!

Our In-Bin Stirrer shows up different unique selling points.
We can build up a stirrer to cover the hole diameter of a silo at once.
In result our stirrers circular drive goes only 180° forwards - end switch - backwards.
We do not need a slip ring contactor (week point in wet conditions)
Each of our stirring augers has a own trolley (M1 until M4) with separate gear drive (M8 until M11)
moved on rack and pinion rails in direction center of the silo or direction side wall.
All drive units are working at the same time, mirror inverted, stopped by end switches and adjustable speed by VFD.
The content of a silo will be stirred multiple times on a day.
We are leading our 150mm diam. serrated augers stressles in vertical position.

The photo shows our toothed rail for the circular motion,

our 150mm special augers vs. the small diam. augers from the competition.

Our drive systems are direct gear drives. Competitors use friction drive systems, which result in slippage!

System start-up: 2-arm silo mixer with 4 carriages and 4 x 150 mm mixing augers in a 3/4 full silo. The guide auger in the middle of the silo proved unnecessary.

Stirators from the USA

Typical stirators from the USA are equipped with the following components:

  • for endless circular drive (needs a slip ring contactor)
  • Friction wheel drive is always timing between ON / OFF, controlled by a tilt switch: If the augers are to much inclined, the circle drive stops (stress for augers, friction wheel and running rail)
  • The 55mm diam. augers have to commute back into a more vertical position for a restart of the friction wheel (relaxation)

All augers are located on one trolley. A indirekt rope drive (slip), combined with the circular drive forces the trolley per round roughly 1,1m to silo center or side wall. I takes several revolutions to reach once silo center……


That should work better!
