    2.What is the working principle of a rotary tablet press?

    The working principle of a rotary tablet press is extremely simple that involves hydraulic pressure or application of pressure.

    Tablet mixture or granules are packed into Die cavity followed by applied pressure with the help of punches such as upper punches and lower punches.

    rotary motion

    Rotary Motion- Working principle of rotary tablet press

    One wheel or main roller is located on the upper side of the upper punch and one wheel or main roller is present below the lower area of the lower punch.


    When compression is applied, the pressure of both punches is transmitted on filled powders into a die cavity and this transforms powders or granules into the form of a tablet.


    The stages involved during this process are :

    • Filling
    • Metering
    • Compression
    • Ejection


    The filling is the first stage of tablet compression. In this stage, filling material is packed into the die cavity. The estimation of filling weight can be achieved by a lower punch in the die.
    To ensure filling material is completely loaded into the die cavity, powders or granules are overfilled. Powder or granules from the hopper is introduced into the feeder. From feeder powders or granules are loaded into the die cavity.

    Filling- Rotary Tablet Press

    Filling- Rotary Tablet Press

    This is the second stage of tablet compression, where weight is adjusted according to the specification of tablets mentioned in the manufactured Batch record.

    An excessive material is removed from tail over die that clears the extra granules when a lower punches cross over the weight adjustment cam. Thus, the weight of a tablet is determined and adjusted by rotating the knob connected to the shaft of the weight adjustment cam. A knob rotation can be done either clockwise or anti-clockwise.


    An illustration of Rotary Tablet Press

    On one side, the weight adjust cam turns upward that lift the lower punch in Die cavity thus filling space get lowers and the weight of the tablet also gets lower as fewer granules are loaded in less space.

    While in the opposite direction lower punch moves down in the cavity that rises the space in the die cavity, so the weight of a tablet is also improved.

    The third, and most important stage is compression. Because in this stage, powder or granular mixture is encounter to compression to form a tablet dosage form.

    Compression- Rotary Tablet Press

    Compression- Rotary Tablet Press

    As we mentioned earlier, the compression is applied using two main rollers, for e.g., upper roller and lower roller.

    So, when punches come closer and pass-through spaces, pressure is transmitted to granular or powdery material to form a tablet.
    This pressure also helps in determining of hardness and thickness of the tablet.
    The lower wheel is connected to a knob and moves up or down by rotation of knob clockwise or anti-clockwise direction.


    Ejection is the fourth and last step of tablet compression. In this stage, an already formed tablet is ejected from the die cavity via lifting the lower punch with the help of an ejection cam. An ejected tablet is assembled into a tablet container using a discharge chute with help of take-off blades. A take-off blade is integrated into the backside of the feeder.
