Ring tablet tablet press machine is a basic equipment for pressing thick material with powder content less than 10% into tablets of various shapes. Because the granules contain too much fine powder, there is air in the granules during compression, and the speed during compression Faster, the gap between the punch and the die hole is smaller, and the air cannot escape from the pellets during compression. Below is a summary of how to resolve splinters in several different situations.
1. Rupture due to excessive pressure
When the particles are subjected to increased pressure, the degree of expansion also increases, and the cohesive force of the adhesive cannot prevent the expansion, resulting in splits, and the pressure should be reduced.
2. The upper punch of the pharmaceutical tablet press does not meet the requirements of the die hole.
The die has been used for a long time and worn for a long time, resulting in the mismatch between the upper punch and the die hole, the upper punch has a sharp inward curl, and the uneven pressure makes the part of the sheet under excessive pressure, resulting in top cracking or deformation of the die ring. Replace with a suitable mold.
3. Particles that do not meet the requirements
When the tablet press is working, the texture is loose and there are too many fine powders, resulting in splits, which should be overcome by adjusting the concentration and dosage of the binder and improving the granulation method.
