The MÖLLER® Twin Shaft Paddle Mixer is used wherever large amounts of ash are produced and must be transported. To avoid dust formation during transport on belt conveyors and open vehicles the ash is sprayed with water in the Twin Shaft Paddle Mixer before transport. The humidified ash can then be transported. The maximum loading capacity amounts to 300 m³/h of wet ash.

At the material inlet the dry ash is fed in controlled quantities into the Twin Shaft Paddle Mixer trough an inlet on the top. In the housing two shafts fitted with conveying and mixing paddles attached with screws rotate in opposite directions, thus circulating and conveying the ash to the material outlet. On the way to the outlet atomised water is sprayed into the ash via high-pressure nozzles and absorbed by the ash.

At the material outlet the ash falls soil-damp, dust-free and without free water residue onto a conveyor belt or directly into a loading facility. For this purpose MÖLLER offers a suitable wet loading device which prevents the vapours produced by the hot ash from escaping to the environment.


The MÖLLER Twin Shaft Paddle Mixer is equipped with a generously dimensioned drive which permits continuous operation. The sturdy and reliable construction has only a few wearing parts and works without a central bearing in the worm trough.

Wear is minimum due to the low speed.

The entire worm trough can be accessed via an inspection flap, which is self-locking via gas pressure shock absorbers. This permits quick and easy inspection and replacement of all important components. Also cleaning of the interior is considerably facilitated. The conveying and mixing paddles are attached to the shafts with screws and can be replaced without dismantling the shaft.
