The device that the tablet press should have
1. The fluidity of fine powder in the device of oscillating feeding powder or forced feeding powder is always not as good as that of particles. It is easy to appear holes in the feeder or flow fast or slow, resulting in a large difference in sheet weight, and the device can make the powder evenly flow into the die hole.
2. Because there is more air in the powder than in the particle, it is easy to produce top crack when pressing the tablet. The solution is to reduce the speed of the tablet, the second is the second compression, that is, the first time for the initial compression, the second time for the final compression into tablets.
Due to the increased compression time, it is beneficial to discharge the air in the powder, reduce the phenomenon of fragmentation, and increase the hardness of the tablet.
3. Good sealing and dust removal device because of the powder has flying, the powder directly press tablet, will produce more dust, sometimes the phenomenon of powder leakage, so the tablet press machine, should have automatic sealing feeding device, good dust removal device and powder scraper and the rotary table between the tight joint.
