Automatic High-speed Rotary Tablet Press

The GZPK Series represents a pinnacle in high-speed rotary tableting technology, engineered for the continuous compression of granules and powders into high-quality tablets. To ensure structural integrity and consistent thickness even at maximum speeds, the press utilizes a two-stage compression system. The initial pre-compression phase removes air and stabilizes the material "slug," while the main compression phase finalizes the tablet form, significantly reducing the risk of capping or lamination.

Precision is maintained through a dual-paddle forced feeder that ensures uniform die cavity filling while minimizing dust emission. Hygiene is prioritized by a triple-circuit centralized lubrication system that protects punches and rollers without risking product contamination.

Operational Principles

1. Feeding: Powder or granules are loaded into the hopper and distributed by a dual-paddle forced feeder.

2. Pre-Compression: Initial pressure is applied to de-aerate the material and stabilize the density.

3. Main Compression: Final force is applied to achieve the target tablet hardness and thickness.

4. Ejection & Monitoring: Tablets are ejected while Tedea-Huntleigh load cells analyze the force of every stroke.

5. Auto-Adjustment: The system automatically adjusts filling depth based on real-time force data to maintain weight consistency.

Key Features and Advantages

• Intelligent Control: Equipped with a Siemens PLC and a 10" HMI for intuitive parameter adjustment (filling depth, pressure, thickness).

• Force Monitoring: Tedea-Huntleigh sensors track tooling wear and feeding status, automatically correcting filling depth to maximize yield.

• High-Precision Turret: Features an anti-corrosion, high-stability turret for long-term operational accuracy.

• Advanced Lubrication: Three independent automatic lubrication circuits prevent mechanical friction and extend the service life of the tooling.

• Safety & Cleanliness: Fully enclosed workspace with optimized dust extraction interfaces to meet strict GMP requirements.
