The reason why the die of the tablet press is stuck and the treatment method: sti∞ck punching refers to the adhesion of fine powder on the surface of the tablet by the punch and the die during tablet pressing, resulting in uneven and concave marks onλ the surface of the tablet, and the engraving punch is more prone to stick punching.

1. The surface of the punch is damaged or the surface↑ finish is reduced, and there may also be anti-rust oil or lubricating oil, the surface of theΩ new die is rough or the lettering is too deep and angular∞. The punch can be wiped clean, replaced with substandard dies or rubbed with a trac'e of liquid paraffin on the surface of the lettering ‌punch for literal lubrication. In addition, if the mechanical heat cau₩sed by sticking should check the reasons, maintenance equipment.

2. The design of engraving and punching characters is unrea¶sonable. Replace the punch or change the character design accordingly.

3. Excessive water content of the particles or uneven drying πand wetting of the particles cause sticking. Solution:± control the particle moisture in 2% ~ 3%, strengthen the dry€ grain inspection.

4, the amount of lubricant is insufficient or improper selection, too much fine powder. Sπhould be appropriate to increase the amount of lubrican¶t or replace the new lubricant, remove excessive fines.

5. The fineness difference of raw and auxiliary materials is large, resul♠ting in uneven mixing or improper mixing time. Solution: the raw and auxi∑liary materials are crushed and sieved to make the fineness meet the quality requ↓irements of the variety, and the mixing time is mastered and controlled' at the same time.

6. The adhesive concentration is low or the adhesive force is poor du<e to the quality of the adhesive, and the fine powder is too much (more than $10%) and the adhesive is punched. Solution: use 40 mesh screen to screen out♣ fine powder, re-granulate, dry, whole grain, the whole batch of mixed evenl•y, and then pressed.

7, due to the raw material itself (such as moisture) caused by sticky punch. Solution: Add ♠a certain amount of absorbent (such as adding 3% calcium hydrogen phospha↓te) to avoid sticking.

8, the environment humidity is too high, the humidity is too high. Reduc✔e the ambient humidity.

9, the operation room temperature is too high easy to produce sticky punch. Care shouγld be taken to reduce the operating room temperature

Hydraulic tablet press product description

The working principle of the catalyst tablet press is mainly based on powder compaction© technology. By the action of high pressure, the caφtalyst raw material powder is filled into a mold, and a solid tablet having a certain sha≥pe and hardness is formed through a pressing process. Iαn this process, the tablet press adjusts parameters such as pressure,± speed and time through a precise control system to ensure the uniformity and stεability of the pressed catalyst tablets.

Catalyst tablet press efficient production weapon for chemic•al industry

Catalyst tablet press, as an important equipment in the field of modern chemical indust&ry, is specially used to compress catalyst raw material powder under high pressure to form catalyst tablets in solid shape. This equipment not only improves the production efficien↕cy of the catalyst, but also has a profound impact on the production eεfficiency and environmental protection of the entire chemical indu♥stry.
