Causes of sticking and stamping of corn tablet press and treatment methods

The adhesive punching of corn tablet press means that the fine powder on the surface of the tablet is adhered to by the punch and the die when the tablet is pressed, resulting in one-sided, uneven and indentation, and the adhesive punching of the lettering punch is more likely to occur.

1, insufficient lubricant or improper selection, too much fine powder. The lubricant should be appropriately increased or replaced with a new intercalated slider to remove too much fine powder.

2, engraving, punching character design is unreasonable. Change the punch or change the character design accordingly.

Too much water in the particles or uneven drying and wetting of the particles cause sticking. Solution: Control particle moisture at about 2% ~3%, strengthen dry particle inspection.

4, due to the raw material itself (such as moisture) caused by sticky punching. Solution: Add a certain amount of absorbent (such as adding 3x calcium hydrogen phosphate) to avoid sticking.

The fineness difference of raw materials is large, resulting in uneven mixing or improper mixing time. Solution: the raw materials are crushed and screened to make its fineness meet the quality requirements of the variety, while mastering and controlling the mixing time.

6, the adhesive concentration is low or due to the adhesive quality causes poor adhesion, too much fine powder (more than 10%) and stick. Solution: Use a 40-purpose screen to sift out the fine powder, re-granulate, dry, whole grain, mix the whole batch evenly, and then press the tablet.

The surface of the punch is damaged or the surface finish is reduced, there may also be anti-rust oil or lubricating oil, the surface of the new die is rough, or the lettering is too deep and angular. The punch can be wiped clean, replace the non-standard die, or rub the surface of the lettering punch with micro-liquid paraffin to lubricate the literal. In addition, if the mechanical heat caused by sticky stamping should check the cause, maintenance equipment.

8. The ambient humidity is too high and the humidity is too high. Reduce the ambient humidity.

9, the operating room temperature is too high easy to produce sticking. Attention should be paid to reducing the operating room temperature.
