Factors affecting the unevenness of small tablet presses

The small tablet press is suitable for production and experiment in pharmaceutical, health care, food, agriculture, chemical, electronic battery, metallurgical ceramics, etc., and is equipped with a set of commonly used tableting molds. A pair of dies are installed on the machine, and the filling depth of the material and the pressure and thickness of the tablet can be adjusted. It can be continuously compressed or hand-cranked when there is no electricity. Easy to use, easy to repair, small size and light weight. Various shapes of molds are available upon request.

When using a small tablet press to press a sheet, sometimes thick slabs appear? There is a thin sheet. In fact, the thick sheet has a great relationship with the material filling of the machine. The position of the upper and lower pressure rollers will also change, so first of all, carefully follow the instructions above. The main reasons are as follows:

1. Material factors, uneven granulation or poor material flow;

2. The wear of the die is caused by different types of sheets or total height difference;

3. The height of the hopper is not properly adjusted, and the filler behind the feeder is insufficient;

4. The filling front rail in the filling rail assembly is seriously worn and a jump is generated. At this time, the filling rail assembly should be replaced;

5. The lifting rod in the filling rail assembly is seriously worn, resulting in a large adjustment gap and a filling rail jitter. At this time, the filling rail assembly should be replaced;

6. The bottom of the feeder is seriously worn, resulting in uneven gap between the bottom surface of the feeder and the turntable;

7. The scraping board is seriously worn, resulting in poor scraping effect. At this time, the scraping board should be replaced;

8. The effect of vacuuming under the punch is poor, resulting in plugging;

9. The amount of lubricant and adhesive is improper, the particles are wet and damp, the particle size is not uniform, the amount of coarse or fine powder is too much, the surface of the punch is rough or the lettering is too deep, the edges are angular, and the machine is abnormally hot.
