How To Adjust The Tablet Weight Of The Tablet Press

Oct 20, 2022
During the punching process of the rotary tablet press, the weight difference of the tablets tends to increase. What should I do?

(1) The length of the die of the rotary tablet press is uneven: the workpiece weight difference may increase, so a caliper should be used to check whether each punch is qualified. If individual reductions may be due to a failed expulsion motion and low particle fill, the individual reductions should be checked to clear the obstruction.

(2) The height of the hopper is not correct: it may cause the particles in one hopper to drop rapidly, the particles on the feeder are many, and the particles accumulate slowly in the other hopper, and the particles on the feeder are few, resulting in imbalance, adding particles to the two hoppers In production, the position of the hopper can be adjusted, a certain number of particles must be maintained and the speed of loss must be maintained. The two hoppers accumulate a similar number of particles, and the particles can be added to the hole.

(3) The feeding hopper is blocked: in the buffer zone of tableting, if the particles used are sticky or wet, sometimes particles tablets or cotton yarn are mixed into the material and cannot flow freely, so the number of particles added to the hole is reduced, which affects the tablet weight and the tablet weight. The weight of the agent is greatly reduced, and the inspection should be stopped immediately.

(4) The reason for the weight change of the tablet is generally due to the machine failure or negligence in the operation of the rotary tablet press, so in this process, it is necessary to do detailed inspection and maintenance work, damage, and measure the tablet at regular intervals. If the tablet weight is normal, the production will continue.
