To produce high-quality pellets, we need not only high requirements for the pellet mills specifically designed for pellet processing, but also for the raw materials used in the equipment. As we know from the types of equipment, there are many varieties of raw materials. So, what are the detailed requirements?

1. Different raw materials have different moisture requirements. Generally, biomass pellet mills require raw materials with a moisture content of around 15%.

2. The maximum size of the raw material for biomass pellet mills must not exceed the die orifice diameter.

3. Hard objects such as iron blocks and stones must not be mixed into the raw materials, otherwise, the equipment will be damaged.

4. High-quality pelleting can be achieved without any additives in the raw materials. However, to increase output and significantly extend the service life of easily worn parts such as dies and rollers, it is recommended to use binders appropriately.

The above are the requirements for raw materials for biomass pellet mills. The most important aspects are the moisture content, size, and hardness of the raw materials. However, this equipment can process many types of raw materials, such as common wood chips, feed, and crop straw. They all have different requirements in these three aspects, and we need to understand their standards in more detail.
