Feed screws

feeding of combustion-chambers, calzinating furnaces, fluidized-bed-systems, waste incinerating plants and other fields of applications.

Even if process-conditions make a bearing on the feeding-side of the shaft unavailable,  Köllemann feed screws are still the optimal choice.
Based on our long-term experience within this segment we offer various options for the geometry of the screw-shaft.
Furthermore we provide the possibility to cool down individual parts of the machine in order to prevent the structure from damaging. If the process conditions require it, we can also heat them. Abrasive bulk-solids will not be a hazard for the service-life of the feed-screw – various options secure an excellent protection against premature wear.
To fulfil your requirements regarding mass-flow and self-cleaning, we can supply different models with multi-shaft-design.
