Part of a tableting machine in which granules for compression are stored.

• A. Hopper
• B. Punch
• C. Die Cavity
• D. Cam Tracks

Answer: (A)

The part that stores granules before compression is the hopper. It acts as a storage bin at the top of the tablet press and feeds a controlled stream of granules into the feed mechanism, ensuring a steady and metered supply to the die cavity for each compression stroke. The die cavity is where the actual tablet forms, the punch is the moving tool that compresses the granules in the die, and cam tracks govern the timing and movement of those punches. Since the question asks about storage of granules prior to compression, the hopper is the correct choice because it is specifically designed to hold and feed the material, not to shape, compress, or move the parts.
