Currently, there are four main types of pressed roller materials used in biomass pellet machines on the market.

Second, high chromium cast iron.

The chromium content in high chromium cast iron is relatively high, which then forms hard carbides, giving it excellent wear resistance and corrosion resistance.

The high-chromium cast iron pressed roller can maintain good working toughness in harsh working environments and resist material wear and corrosion.

However, high-chromium cast iron is relatively brittle and may break when subjected to large impact loads.
