In actual production, the production capacity of the wood chip pellet machine production line can rarely reach its designed production capacity. The production capacity of wood chip pellet machine is the bottleneck of the entire production process. This paper analyzes the many factors affecting the production capacity of wood chip pellet machines as follows.
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 particles are pressed too hard, and the output is also low; the compression ratio of the ring mold is too small, and the particles 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 particles 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 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 rollers are worn. If the wear is serious, the ring mold can be processed and repaired, which will re-counter the worn cone holes. The wear of the pressure rollers must be replaced. The wear of the ring mold cone holes has a great impact on the output.
3. The gap between the ring mold and the press roller needs to be adjusted correctly. If the distance is too small, the press roller will rub against the ring mold, shortening the service life of the ring mold. If the distance is too large, the press roller will 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 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.
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 will not only extend the service life of the ring mold, but also make the discharge smoother.
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 particles 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.
