This equipment is very common in the fuel feeding system and in the many applications that suffer clogging issues.
In different industries, this equipment is the best solution to retrofit existing silos or hoppers that suffer bridging or material clogging. Another advantage of this solution is the complete elimination of the compressed air consumption for fluidization that is not longer required. The system can be also installed in ATEX classified area by using specific functional parameter and materials in contact with the materials to be conveyed.
Cooled Screw Conveyor
Water cooled screw conveyors are used in the industrial application when the material with high temperature – up to 1000 °C – needs to be cooled down. The water-cooling system includes an external jacket and, in some cases, also a cooled shaft and flights to meet the required performance. Trough or Pipe type, these kinds of conveyors are generally used in case of small capacity – few t/h – and with a length not higher than 12 m.
All bearing supports are installed externally and the shaft includes stuffing box and rotation joint – if any – to connect the conveyor to the water network.
The construction material is selected mainly in accordance with the design temperature and can be carbon steel up to high quality stainless steel.

Tailor made solutions are possible for special applications.
Lump Breaker
Our Lump Breaker reduces compacted, lumpy and agglomerated materials from silos, hoppers, filters to their original particle sizes and flowability, making them suitable for downstream processing and/or conveying in particular for pneumatic systems. The double rotor type ensures high flow capacity forcing lumps against the hardened teeth without overworking, until material returns to its original particle size – without generating excessive dust. Lump Breaker includes double rotor with direct coupling gearbox and external bearing to facilitate the maintenance activities. In case the downstream process requires a control of the max material size, the Lump Breaker is equipped with a grid that create a recirculation of the material until the size gets down to the required particle size. Some applications need a special design for high temperature, sticky material or very abrasive application. The material construction is selected according to our experience and process parameters.
