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 the speed. In addition, when the difference of sheet weight is found in the process of dual-track tablet press, the sheet weight regulator and pressure regulator of bilateral rails should be adjusted respectively. The consistency of the technical parameters of the track weight regulator and the pressure regulator should be taken as the criterion by the actual adjusting data of each track.

(2) When the particles that meet the quality requirements and have appropriate fluidity and compressibility are pressed, there are also lobes, loose flakes, sticky flakes, slow disintegration, surface spots and other situations. In case of differences in weight between lobes and flakes, the speed should be slowed down. Due to the different height of the feeder device, the speed of adding particles is different and the blockage of the feeder affects the weight of the piece and the pressure can be increased. Lack of pressure caused by loose sheet, only the appropriate pressure should be adjusted.
