Rotary Tablet Press Machine

Description

Rotary Tablet Press Machine is a high-speed, automated mechanical device used in the pharmaceutical, nutraceutical, confectionery, and chemical industries to compress powder or granular materials into uniform tablets or pills. It is one of the most efficient and widely used machines for large-scale tablet production.

 

  • Die Filling: Lower punch drops; powder flows from hopper into the die.

 

  • Pre-compression(optional): Light compression to remove air.

 

  • Main Compression: Upper and lower punches meet under high pressure to form the tablet.

 

  • Ejection: Lower punch rises to push the tablet out.

 

  • Tablet Discharge: Tablets are scraped off and collected.

Working Principle of Rotary Tablet Press Machine

Tablet compression machine basically works on hydraulic pressure. This pressure perform key role in any type of Tablet Machine. It transmitted unreduced through the static fluid. Any external applied pressure is transmitted through static fluid to all directions in the same proposition. which resulting make suitable to increase pressure. To form a tablet, the granulated powder material must be metered into a cavity formed by two punches and a die, and then the punches must be pressed together with great force to fuse the material together. There are two types of tablet presses called Single Station Tablet Press and Multi Station Tablet Press. Working of these machines differs in terms of production output and feature requirements.

Key Features of Rotary Tablet Press Machine

  • Rotary Motion:
    • Operates on a rotating turret (turntable) that holds multiple sets of punches and dies.
    • The turret rotates continuously, allowing simultaneous filling, compression, and ejection of tablets.

 

  • Main Components:
    • Upper punches: Apply top compression.
    • Lower punches: Support the powder and eject the tablet.
    • Dies: Cavities where powder is filled and compressed.
    • Feeder system: Delivers powder/granules into the die.
    • Cam tracks: Control punch movement (filling, compression, ejection).
    • Compression rollers: Apply force to compress the powder.
    • Hopper: Stores the raw material (powder/granules).

FAQ for Rotary Tablet Press Machine

The machine operates on the principle of hydraulic pressure using a rotating turret. Powder flows into die cavities as lower punches drop. The upper and lower punches then apply pre-compression and main compression forces to form the tablet. The turret rotates continuously, with cam tracks guiding punches through filling, compression, and ejection stages, allowing simultaneous production across multiple stations.

  • Compact GMP-compliant design with powerful pre- and main compression forces (up to 100 KN).
  • Turret driven by a centrally fitted oil-immersed gearbox with speeds up to 70 RPM.
  • Available with optional two-layer tablet compression, PLC/HMI controls, auto lubrication, and pneumatic powder loading.
  • Features upper punch penetration adjustment, anti-vibration mounts, safety interlocks, and hydro-pneumatic pressure control.
  • Tooling options in D, B, and BB configurations.

The machine is available in models such as 16D, 20D, 24D, and 37D with output ranging from 13,440 to 222,000 tablets per hour. It supports maximum tablet diameters up to 25mm, compression forces up to 100 KN, and various tooling types. Specifications vary by model to suit different production scales.

Advantages include high production speed and consistency, uniform tablet weight/hardness/thickness, suitability for large-scale manufacturing, support for various tablet shapes, and low maintenance with automated controls. Applications span the Pharmaceutical, Biotech, Ayurvedic, Herbal, and Nutraceutical industries for efficient solid dosage form production.
