The TFC is an easy-to-operate roll compactor system designed for continuous dry granulation processes. The TFC 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 re-circulated back into the TFC hopper where the product can be reprocessed. Production rates up to 600 kg/hr are available.
The pressure applied to the product within the compaction zone determines the final bulk density of granulation. Even though the roll gap may vary due to incoming product inconsistencies, the constant compaction pressure ensures granulation uniformity.
The TFC Roll Compactor features a unique roll shape and seal design that reduces the creation of fines during the process. A Concavo-Convex roll design is standard for all TFC systems. This design contains product within the compaction zone, minimizes powder leakage through the sides of the rolls, and ensures more uniform compaction pressure across the width of the rolls. The top and side seals are integrated directly into the roll design, reducing fines and improving processing yields.
Product is delivered to the compaction zone with a tapered screw feeding system that effectively expresses entrapped air against the side walls. Any air remaining within the product can be removed, if needed, via an optional vacuum deaeration system.
