TFC Roll Compaction Technologies

Continuous Dry Granulation

The TFC Roll Compaction systems are a continuous, directly compressible, dry granulation system to improve material flow characteristics and increase material density. A vertical product flow system uses a tapered feed screw to deliver the material to the fully contained compaction zone of the cantilevered rolls, increasing product yields and minimizing product fines.

TFC-520 Roll Compaction system capable of 5kg – 130kg/hrThe TFC Roll Compaction systems utilizes a unique roll system to compact powders into sheets or briquettes. The compacted sheets are milled to produce granules of a specific size. Particles that fall outside the desired size range can be recirculated back into the roll compaction system hopper, where the product can be reprocessed.

Roll Gap Control Produces Optimum Granulation

Granule size is dependent upon compaction forces. With that in mind, the TFC offers the most comprehensive methods of controlling roll gap during the process. First, the TFC utilizes a floating roll to ensure compaction forces are consistent regardless of variations of incoming material flow. In addition, the TFC control system allows the operator to enter the desired gap within a suitable range. The TFC system will control to that gap setpoint, on average, ensuring a consistent granule is always produced – regardless of variations of the incoming materials.

Conical Hopper Eliminates Air Entrained in Product

As product is being fed into the compaction zone through the tapered screw feeding system, the powder is pre-compacted and entrapped air is forced out along the side walls of the product hopper. The inherent advantage of the vertical hopper eliminates any requirement for a de-aeration system within the nip zone.
