The Reason For The Difference Of Tablet Weight Produced By Tablet Press Machine

The Reason For The Difference Of Tablet Weight Produced By Tablet Press Machine

(1) The length of the punch of the tablet press is not uniform, which is easy to cause the increase of the difference in the weight of the tablet. Therefore, before use, the caliper will be used to check each punch after passing the inspection. If there is an individual reduction, the punching movement may fail, resulting in less filling of particles than others.

(2), the rotary tablet press feed hopper device of on any account is wrong, can be caused by particles in a hopper fall faster, and feeder on the accumulation of particles, the particles in a hopper speed is slow, and less accumulation of particles on feeder, which joined the particles when die imbalance, can adjust the position of the feed hopper, The particles in the two feeders should keep a certain number and falling speed equal, the particles stacked on the two feeders are similar, and the particles can be evenly added into the die hole.

(3), the rotary tablet press particles caused by the change of sheet weight, particles too wet, too much fine powder, particle thickness difference is too large, and the lubricant in the particle is insufficient, also can cause the change of sheet weight difference guide, should improve the particle quality.

(4) The cause of the weight change of the automatic tablet press is caused by the fault of the tablet press or the negligence of the work. Therefore, in the process of tablet pressing, it is necessary to do the maintenance work of the machine, check the damage of the machine in detail, and weigh the piece once every certain time (10-20 minutes), and whether the piece weight is in accordance with the provisions
