What Should I Do If The Tablet Press Often Has Chipping Problems?

Aug 09, 2021

The tablet press is a machine that presses dry granular or powdery materials into tablets through a mold.

According to different models, tablet presses can be divided into single-punch tablet presses, flower basket tablet presses, rotary tablet presses, sub-high-speed rotary tablet presses, fully automatic high-speed tablet presses and rotary core-spun presses Tableting machine.

The function and application range of different types of tablet presses are different, but they usually encounter the same problem, that is, the problem of fragmentation.

Then why does a split occur? The main reason is that there is too much fine powder in the particles.

There is air in the particles during compression. The speed during compression is relatively fast.

The gap between the punch and the die hole is relatively small, and the air is not removed from the particles during compression. , Is enclosed in the sheet, when there is no pressure, the air will expand, which will cause splits.

Lobes due to excessive pressure of tablet compress machine

When the pressure of the particles increases, the degree of swelling also increases, and the binding force of the adhesive cannot prevent its swelling, so it will cause cracks, so the pressure should be reduced.

The split due to the upper punching and die hole not meeting the requirements

The die used for a long time is gradually worn out, which causes the upper punch to be incorrectly aligned with the die hole.

The upper punch has a sharp inward curling, and the uneven pressure makes the part of the film excessively compressed, causing topping or die ring If the sample is deformed, the appropriate mold of automatic tablet compress machine should be replaced in time.
