Mechanical conditions of tablet press Tablet press is another element of sheet forming. The quality of tablets is directly affected by the performance of the specifications, the mechanical condition of the equipment in operation and some important parts of the tablet press, such as the wear of the die. (1) from the size of the model, rotary tablet press than the impact of the tablet press pressure, and uniform, sliver phenomenon is easy to control. Because the feeding hopper is fixed, the machine vibration is small, the particle stratification phenomenon is less, the sheet weight is accurate and stable. But the rotary tablet press has a variety of single-track and dual-track models. In the production of sliver, loose sliver, sheet weight difference, to consider the double track press speed, particle compression time is shorter than the monorail type, easy to produce sliver, loose sliver phenomenon. At this time should pay attention to the appropriate increase pressure, slow down
