SED-660-75GY-D — High-Speed Rotary Tablet Press

Granular or powdery materials are loaded into the 75 ISO-BB die holes by a three-impeller force feeder. Upper and lower punches mounted on the rotating turret follow a closed circular up-down trajectory guided by upper and lower rail assemblies. As the turret rotates, (1) the lower punch descends via the pull-down guide for over-filling, (2) the fill guide levels the fill to precise weight, (3) the scraper removes excess granules, (4) upper and lower punches simultaneously compress the material through pre-press rollers then main-press rollers—trapped air escapes, improving tablet density uniformity and reducing capping. After compression, the lower punch rises via the discharge guide and ejects the tablet from the die hole. Each rotation of the turret completes two full press cycles (double-outlet), yielding two tablets per die per revolution. A rotary encoder, pressure sensor, and reject solenoid eliminate off-spec tablets in-line. VFD servo replaces manual handwheels for speed, fill, and pressure adjustments. All process parameters are recorded per production batch via PLC.
