‌Biomass pellet machine roller shell cover more durable materials including alloy steel, high chromium cast iron ‌. Because of its high strength, high wear resistance and good corrosion resistance, these materials can effectively improve the production efficiency and service life of the biomass pellet machine.
To be specific: 1.‌ Alloy steel: alloy steel is a kind of high strength, high hardness material, excellent wear resistance. When subjected to high pressure and high speed operation, the alloy steel roller can maintain stable performance, thus greatly extending the service life. Despite the relatively high cost of alloy steel, its stable performance and long service life make it a good choice for pellet roller shell.

2.‌ High chromium cast iron: high chromium cast iron is also a high-quality pellet press roll material. Its wear resistance is excellent, suitable for long-term, high-strength use environment. The selection of high chromium cast iron as the press roller material can effectively improve the production efficiency and product quality.
In the selection of biomass pellet machine roller shell, in addition to considering the durability of the material, it is also necessary to comprehensively consider the specific production needs, budget and the model of the pellet machine, to ensure the selection of the most suitable roller shell material.
