Improving output, saving energy consumption for granulation, and increasing the life of pellet machine molds and press rollers has always been a research topic in the pellet industry. To reduce and improve the wear of the wood pellet machine press roller and extend its service life, the following three major factors affecting the life of the pellet machine press roller are very important:

1. Selection and process of pellet machine press roller material

The composition and properties of the metal material of the press roller are prerequisites for determining its wear resistance. With high-quality materials combined with secondary quenching high-temperature heat treatment process, the service life of the press roller skin can be longer.

2. Types of granular raw materials

For example, raw materials such as corn stalks, peanut shells, tree roots, building forms, etc. contain more impurities such as sand and gravel. Processing these raw materials will greatly reduce the service life of the rolling roll skin.

3. The gap between the press roller and the mold

If the gap between the press roller and the mold is too small, it will cause direct contact between the two, which will reduce the service life of the press roller and the mold. If the gap between the two is too large, it will cause poor particle forming.

Therefore, the adjustment and use of the press roller of the wood pellet machine is of particular importance. Only by using it scientifically and reasonably can the service life of the press roller be extended and its use efficiency will be improved.
