Reasons For Difference Of Tablet Weight In Tablet Press Machine

Reasons For Difference Of Tablet Weight In Tablet Press Machine

(1) The uneven length of the punches of the tablet press is easy to increase the difference in tablet weight. Therefore, before use, use a caliper to check each punch to be qualified before reuse. In case of individual reduction, it may lead to failure of the downward movement, resulting in less filling amount of particles than others. It is necessary to check the individual downward movement of the full-automatic tablet press and remove the obstacles.

(2) If the height device of the feeding hopper of the rotary tablet press is not correct, the falling speed of the particles in one feeding hopper will be faster, while the particles accumulated on the feeder will be more, and the falling speed of the particles in the other feeding hopper will be slower, while the particles accumulated on the feeder will be less, resulting in the imbalance when the particles are added into the mold hole. The position of the feeding hopper can be adjusted to keep a certain number of particles in the two feeding hoppers and the falling speed equal, The particles accumulated on the two feeders are similar, and the particles can be uniformly added into the mold holes.

(3) The particles of the rotary tablet press cause the change of the tablet weight, the particles are too wet, the fine powder is too much, the particle size difference is too large, and the lubricant in the particles is insufficient, which can also cause the change of the differential conductance of the tablet weight, so the particle quality should be improved.

(4) The reason for the change of the tablet weight of the automatic tablet press is generally caused by the failure of the tablet press or negligence in work. Therefore, during the tablet pressing process, it is necessary to maintain the machine parts, carefully check whether the machine parts are damaged, and weigh the tablet weight every certain time (10-20 minutes) to see whether the tablet weight meets the requirements
