Bamboo pellet machine sometimes have symptoms of not being discharged or having difficulty discharged or low yield, which makes many inexperienced users not know how to deal with these situations. In summary, there are two major aspects that affect the discharge problem or output. One is that the machine itself is not well adjusted, and the other is that the raw materials for pressing pellets are not well matched. This aspect of the machine itself mainly appears in the mold and press roller link.

Causes of difficult discharge of bamboo pellet machine and low yield:

1. If you are using a new ring mold, first check whether the compression ratio of the ring mold matches the processed raw materials. The compression ratio of the ring mold is too large, the resistance of the powder through the mold hole is large, the pellets are pressed too hard, and the output is also low; the compression ratio of the ring mold is too small, and the pellets are pressed out and not formed. The ring mold compression ratio must be re-selected and then check the smoothness of the inner hole of the ring mold and whether the ring mold is not round. The inferior ring mold is because the inner hole of the ring mold is rough and the ring mold is not round, resulting in large discharge resistance, the pellets are not smooth, and the discharge is difficult, and the output is lower. Therefore, high-quality ring mold must be used.

2. If the ring mold of the granulator is used for a period of time, it is necessary to check whether the cone holes in the inner wall of the ring mold are worn and whether the pressure roller is worn. If the wear is serious, the ring mold can be processed and repaired, which will re-counter the wear of the worn cone holes. The wear of the pressure roller must be replaced. The wear of the cone holes of the ring mold has a great impact on the output. 

3. The gap between the ring mold and the press roller needs to be adjusted correctly. When producing livestock and poultry materials, it is generally appropriate to have a spacing of about 0.5mm. Too small distance will cause the press roller to rub against the ring mold, shortening the service life of the ring mold. Too large distance will cause the press roller to slip and reduce the output. 

4. Pay attention to the conditioning time and quality of raw materials, especially to control the moisture content of raw materials before entering the pellet machine. The moisture content of raw materials is generally 13% before conditioning. If the moisture content is too high and the moisture content of raw materials is too high after conditioning (moisture ≥20%), it will cause slippage in the mold and it is not easy to discharge. The gap between the ring mold and the press roller needs to be adjusted correctly

5. Check the distribution of raw materials in the ring mold. The raw materials cannot be allowed to run single-sided. If similar situations occur, the position of the large and small feed scraper must be adjusted to allow the raw materials to be evenly distributed in the ring mold. This can not only extend the service life of the ring mold, but also smoother discharge.

The moisture content of this material must also be controlled well, because excessive moisture content will directly affect the forming rate and yield of the pressed pellets of this machine. Therefore, the humidity measurement instrument can be used to test the raw materials when they enter the machine to check whether the humidity of the material is within a reasonable granulation range. To make the machine efficient and high-yield work, it is necessary to debug every link of the work.
