How to solve the problem of unstable pressure of tablet press?

First of all, the working principle of the rotary tablet press is that under the action of the upper and lower main pressure wheels, the upper and lower punches move relative to each other to press the material into shape. The position of the main pressure roller is relatively fixed. If the serious wear of the punch is excluded, it should be the cause of the material. The higher the material density, the smaller the volume at the same weight, and the smaller the hardness at the same tablet thickness; the smaller the material density, the larger the volume at the same weight, and the higher the hardness at the same tablet thickness. In addition, at what level can the control range of your tablet press machine's loading capacity be controlled? Is the consistency the same? If it is the same, it should be uneven mixing. If the meaning of consistency is within a certain range, it is normal for the hardness to fluctuate to a certain extent. Besides, the unit of measurement N is too small, if there is any fluctuation
