The biomass pellet molding effect is not good? Here comes the reason analysis

If the pellets are loose or not formed during the processing, many users will first react that there is something wrong with the machine. Of course, we must first check whether all parts of the machine are normal and find out the crux through debugging. If the equipment is normal, there are other reasons. We have specifically summarized the three most common ones.
1. The problem of the raw materials themselves
Different raw materials have different characteristics, different fiber structures, and different degrees of difficulty in molding. For example, palm is a material that is difficult to press, and sawdust has its own bonding effect at a high temperature of 80 degrees, so no adhesive is required. In addition, if it is a mixed material, the mixing ratio of each material will also affect the molding rate.

2. Moisture content of raw materials
For biomass pellets, the moisture content of the raw materials is an important indicator. If the moisture content is too high, the pellets will be very soft and difficult to form. In this case, a drying process must be used to achieve normal pelleting of the pellet machine. The moisture content is generally around 15%.
3. Particle size of raw materials
The length of the raw material particle size is also an important factor affecting pelleting. Usually the crushing particle size is about 3-4mm and cannot be greater than 5mm. The smaller the crushing particle size, the easier it is to form, but too small is not good, and there will be too much powder content. If the particle size is too large, the pelletizing equipment will not be able to operate normally and effectively, resulting in high energy consumption and low output, uneven pelleting and surface cracks of the finished pellets, which will greatly affect production efficiency.
