Chip Weight Difference Exceeds The Standard Solution

Chip Weight Difference Exceeds The Standard Solution

1: Tablet rotary tablet press will have such a situation is that the distribution of particle thickness is not uniform, the flow rate of particles is different when pressing tablets, resulting in the uneven thickness of particles filled into the die hole, so our solution is to mix the particles or screen out too much fine powder.

2: if there is fine powder adhering to the punch in the dark channel of the tablet machine, the difference in the weight of the tablet can be large when the hanging punch is caused. Then we at this time the down stroke rotation is not flexible, should be timely check, remove the die, clean up the down stroke and die hole.

3: particle fluidity is not good, the amount of particles flowing into the die hole is more or less, causing the difference in sheet weight is too large and beyond the limit. We should re-granulate or add appropriate flow AIDS such as micro powder silica gel to improve the fluidity of particles.

4: Tablet automatic rotary tablet press particle stratification. The particles should be stratified to reduce the size difference.

5: smaller tablets choose larger particles of material. We should choose the right size particles.

6: the feeding hopper of the automatic tablet press is blocked, which often occurs in drugs with strong viscosity or wetting ability. We should dredge the hopper, keep the pressing environment dry, and add the appropriate flow aid to solve.

7: the material storage capacity of the material is different. Keep it under 50%.

8: the feeder of the automatic rotary tablet press is not balanced or installed in place, resulting in uneven packing. Balance feeder or installed in place.

9: powder scraper is uneven or poorly installed. Leveling.

10: with forced feeder, the speed of the forced feeder wheel does not match the speed of the turntable. The agreement.

11: The punch of the tablet press is not consistent with the middle die hole, for example, more powder is leaked between the outer wall of the punch and the die hole, resulting in the phenomenon of "astringent punching" in the punch, resulting in insufficient material filling. In this regard, the punch and middle die should be replaced.
