Rotary tablet press use precautions:
1. Do not remove the protective cover and safety cover on the machine and it should be installed.
2. The die needs to undergo strict flaw detection test and shape inspection. It should be free from cracks, deformation, missing edges, hardness and size. If it is not qualified, do not use it to avoid serious damage to the machine.
3. The feeder device is flat with the turntable surface, high and low accuracy. If it is high, it will cause leakage of powder, while at low, it will affect the quality of the tablet.
4. Do not use raw materials with a lot of fine powder, because it will make more flying powder, and more leakage under the impact, which will affect the wear and tear of the parts and the loss of raw materials.
5. Do not use materials that are not dry, as it will cause the powder to stick to the punch surface.
6. If there are jumps or stagnation during operation, do not use your hands to avoid accidents.
7. The motor should be started before driving, and then the clutch should be started after the operation is normal.
8. If you find that the vibration is abnormal or abnormal noise occurs during use, you should stop the vehicle immediately.
9. The pressure during use should not be too large, generally measured by the load of the motor. The heavy load current of the 380 volt motor at the time of tableting is not more than 4 amps.
10. Increase in disc weight: In the process of adding, the difference in weight can not exceed the limits prescribed by the Pharmacopoeia.
Rotary tablet press method for adjusting the weight of tablets:
During the pressing process, the difference in the weight of the tablets is often found to increase, and the reasons and treatments are as follows:
(1) The length of the punch is not uniform: it is easy to cause the difference in the weight of the punch to increase, so use each caliper to pass the test before use. If there is an individual reduction, it may be due to the failure of the undershooting movement, resulting in less filling of the particles than the other. The individual undershoot should be checked to remove the obstacle.
(2) If the hopper height is low, the granules in a hopper can be dropped quickly, and the particles accumulated on the feeder are more. The speed of the particles in the other hopper is slower, and the hopper is stacked. The particles are small, which causes the particles to be unbalanced when they are added to the die hole. The position of the hopper can be adjusted so that the particles in the two hoppers should be kept at a certain amount and the falling speed is equal. The particles accumulated on the two feeders are similar, and the particles can be made Add evenly into the die hole.
(3) Blocking of the hopper or feeder: When the tablet is pressed, if the particles used are small, sticky or wet, and occasionally the cotton yarn head and the foreign matter in the granules are mixed, the flow is not smooth, and the particles added to the die hole are reduced. It will affect the weight of the film. If the weight of the film suddenly decreases, stop it immediately.
(4) Particles cause changes in tablet weight: particles are too wet, too much fine powder, excessive difference in particle size and insufficient lubricant in the particles, can also cause changes in the difference in tablet weight, and should improve the quality of the particles.
(5) The cause of the change in the weight of the film is caused by the failure of the tablet press or the negligence of the work. Therefore, during the tableting process, the maintenance work of the machine should be done to check the damage of the machine in detail. The film is weighed once every certain time (10-20 minutes), and the film overlaps the rule.
