The salt tablet press machine is a double-pressure rotary tablet press designed to continuously compress granular salt and other suitable granular materials into round or shaped tablets.
The salt tablet machine has 29 punching dies, a maximum tableting force of 120 kN, and a production capacity of up to 90,000 tablets per hour. It is suitable for continuous salt tablet production where stable output and adjustable tablet specifications are required.
Key features of salt tablet making machine
- The maximum tableting force reaches 120 kN, providing the compression force required for producing dense tablets from suitable granular materials.
- With 29 punching dies and a turntable speed of 5–26 rpm, the salt tablet press machine can reach a maximum production capacity of 90,000 pieces/hour under suitable operating conditions.
- The turntable speed can be adjusted between 5 and 26 rpm through a variable-frequency speed control system. Operators can adjust the running speed according to the material and production requirements.
- The salt press machine is equipped with an overload protection device. When the compression pressure exceeds the permitted range, the alarm light flashes and the machine automatically stops.
- The external enclosure and internal working surface of the tablet pressing chamber are made of stainless steel. The turntable is specially treated to provide a smooth, wear-resistant working surface.
- The centralized lubrication system supplies lubricant to multiple lubrication points, helping maintain the transmission and moving components during continuous operation.
- The lower punch guide rail and lower pressure wheel also use a special installation structure designed to make replacement and maintenance easier.
- Our salt tablet pressing machine can be equipped with either a forced feeding system or a conventional feeding system according to the feeding characteristics of different materials.



ZP29D salt tablet press machine specifications
The following parameters define the main working capacity and size of the ZP29D salt block press machine:
| Parameter | Specification |
|---|---|
| モデル | ZP29D |
| Number of punching dies | 29 |
| Maximum tableting force | 120 kN |
| Maximum tableting diameter | 25 mm |
| Maximum filling depth | 24 mm |
| Maximum tableting thickness | 12 mm |
| Turntable speed | 5–26 rpm |

The 5–26 rpm adjustable turntable speed allows the ZP29D to adapt to different production requirements. The actual output depends on factors such as material characteristics, tablet size, filling depth, and operating speed.
What can ZP29D salt tablet press machine produce?
The salt tablet making machine is primarily designed for compressing granular and powdery materials into compact tablets or blocks.
In addition to salt, it can also process other suitable materials, such as mineral powder, fertilizer powder, activated carbon, feed materials, and other compressible industrial materials.
With different punches and dies, the machine can produce various product shapes according to production requirements, including:
- Round tablets
- Oval tablets
- Rectangular blocks
- Special-shaped tablets


How does a salt block press machine work?
The ZP29D salt tablet press machine uses a rotary continuous compression system. Granular material is fed into the tablet press and distributed into the die holes on the rotating turntable.
As the turntable rotates, the punches move through the compression system. The material inside each die is compressed under pressure and formed into a tablet. The finished tablets are then discharged from the machine, while the next cycle continues automatically.
