Working Principle of High-Speed Tableting Machines
The working principle of high-speed tableting machines is based on the efficient compression of granulated powder into tablets. Here is a step-by-step breakdown of the process:
- Filling: The granulated powder is fed into the machine’s hopper. The hopper, equipped with an imported butterfly valve, ensures a consistent flow of powder into the die cavity.
- Metering: The amount of powder entering the die cavity is precisely controlled by the filling cams. The Accura machine offers three types of filling cams, allowing for flexibility in tablet production.
- Compression: The granulated powder is compressed within the die cavity using upper and lower punches. The hydraulic power pack ensures that the required pressure is applied uniformly.
- Pre-Compression: As a standard feature, pre-compression ensures that the powder particles are adequately bonded before the final compression, enhancing tablet integrity.
- Ejection: After compression, the lower punch rises to eject the formed tablet, which is then guided out through the discharge chute.
Maintenance and Troubleshooting
Regular maintenance is crucial to ensure the longevity and optimal performance of high-speed tableting machines. Here are some maintenance tips and common troubleshooting steps:
- Lubrication: Ensure that the one-shot lubrication system is functioning correctly to reduce friction and wear on moving parts.
- Inspection of Punches and Dies: Regularly inspect and replace worn punches and dies to maintain tablet quality.
- Cleaning: Thoroughly clean the machine to prevent contamination and ensure compliance with cGMP standards.
- Calibration: Periodically calibrate the machine’s controls to maintain precision and consistency in tablet production.
- Troubleshooting Common Issues:
- Tablet Weight Variation: Ensure consistent powder flow and check for worn filling cams.
- Capping and Lamination: Adjust compression force and check for proper lubrication.
- Sticking: Increase lubrication and ensure the granulated powder is of high quality.
