Rotary Press Advantages

This type of rotary press provides numerous benefits for the user. Here are some key advantages of using a rotary tablet press.

High productivity can be gained with a minimal amount of labor, while still saving the user money.

Rotary press has an output of between 9,000 -234,000 tabs/hour, which saves time and allows user to meet a high demand of tablet dosage forms.

Allows for independent control of both weight and hardness.

Rotary press decreases waste of valuable formulation. Automatically manage the powder-filled cavity with a moving feeder.

Differences Between a Single Punch & Rotary Tablet Press

There are two key differences between a single punch tablet press and a rotary tablet press:

  1. A single punch tablet press utilizes a single-sided compression in order to make tablets, whereas a rotary press uses double-sided compression.
  2. The compression cycles for single punch tablet presses do not have a dwell time. Whereas rotary presses typically use a punch head flat, which enables a dwell time as the punch passes under the compression roller.

Functional Parts of a Rotary Press

Here are the common components of a rotary tablet press. All of the used rotary tablet presses we sell are fully refurbished.

  • Die cavity: The die cavity is where the powder granules are compressed into tablets. It determines the diameter of the tablets, the size of the tablets, and to some extent the thickness of the tablets.
  • Hopper: the hopper holds the granules/powder mixture that are to be compressed into tablets.
  • Feed paddle: helps to force the feed/the granules into the dies, especially during the faster rotation periods.
  • Punches: this comprises the upper and lower punches, as they move within the die bore to compress granules into tablets.
  • Cam tracks: the cam tracks guide the movement of both the upper and lower punches.
  • Lower cam track: this part guides the lower punch during the filling stage, so that the die bore is overfilled to allow for accurate adjustments.
  • Ejection cam: guides the lower punch upwards facilitating the ejection of tablets from the die cavity after compression.
  • Department of fill/capacity control: this aspect adjusts the lower punch track during the latter part of the fill stage in order to make sure that the appropriate quantity of granules remains within the die prior to compression.
  • Pre-compression rollers: this type of roller gives the granules an initial compression force to get rid of excess air that may be entrapped inside the die.
  • Main compression: This roller applies the final compression force that is required for the formation of the tablets.
  • Take-off blade: this blade is fitted in front of the feeder housing. It deflects the tablet down the discharge chute.
  • Discharge chute: This is where the tablet passes through for collection after being deflected by the take-off blade.
