Working Principle

Working Principle of ZP Rotary Tablet Press

Working principle of GZPK high-speed rotary tablet press
Core process flow: powder → metering filling → tableting → demoulding → quality control
1. Feeding and quantitative filling

Hopper Feed:
Volumetric Filling:
2. Pre-pressing and main pressing

Pre-compression Rollers:
The die rolls under the pre-compression rollers to gently compact the powder and expel air (reduce flakes/sticking).

Main Compression Rollers:
The high-pressure main compression rollers roll to apply 10-100 kN pressure (adjustable) to permanently compress the powder into a dense tablet.

3. Demolding and tableting
4. Online quality monitoring

Abnormal pressure increase → indicates mold wear/foreign matter mixing

Abnormal pressure decrease → indicates insufficient filling/cutoff

5. Automation subsystem coordination

Details Images

This equipment [Stepped three-impeller feeder]

The equipment adopts [three-stage transmission]

[Stable hydraulic system]

Large-area overfilling design, extended quantitative section, and high-precision forced feeding system make tablet weight difference control more accurate;
Double-layer stepped design buffers the impact of falling materials, effectively utilizes the feeding area, avoids parallel feeding blind spots, and eliminates feeding dead angles;

It adopts a three-stage transmission system (pulley combination, turbine pair, gear pair). The main shaft does not rotate and is firmly connected to the machine base. The main motor power directly drives the punching disc to rotate;
The punching disc rotates around the fixed main shaft, so that the punching disc surface runout and warp runout are both close to zero, greatly improving the rotation stability;
The amount of powder leakage is small, saving the waste caused by powder leakage;

The hydraulic pump station and accumulator form a static pressure-maintaining system, which realizes the elastic support and overload protection of the pre-pressing wheel and the main pressing wheel, and ensures the stability and low noise of the tablet pressing process.

FAQ

Q: What is the function of a tablet press?
A: Powder or granular materials are pressed into tablets of specific shapes (such as round, special shapes), sizes and hardness through a mold. They are widely used in pharmaceuticals (tablets), health foods (calcium tablets), chemicals (disinfection tablets) and other fields.

Q: What types of tablet presses are there?
A: Single-punch tablet press: manual/electric, suitable for small-batch R&D or laboratories.

Rotary multi-punch tablet press: high-speed continuous production (common 16 to 75 punches), industrial mainstream.

High-speed servo tablet press: precise control of pressure and speed, used for high-demand products.

Q: How to adjust the tablet weight?
A: Adjust the filling depth: control the material volume by adjusting the depth of the lower punch entering the middle die.

Adjust the particle flowability: ensure uniform filling of the material (great influence by humidity and particle size).

Q: How to control the hardness/thickness of the tablet?
A: Pressure adjustment: increasing the pressure can increase the hardness (but too high may cause cracking).

Upper punch stroke adjustment: control the final position during compression (directly affects the thickness).

Q: What determines the tableting speed (output)?

A: Number of punches (e.g. 55 punches > 35 punches).

Rotary table speed (RPM).

Material properties (speed should be reduced for poor fluidity).
