Roller Assembly Complete Set (Biomass Pellet Machine): A core matching part for biomass pellet machines, compatible with ring/flat die molds. Pre-assembled (pressure rollers, bearings, etc.) for direct use, with multi-layer dustproof seal, anti-leakage, wear-resistant, suits biomass raw materials and harsh working conditions, easy to maintain.

Roller Shell (Biomass Pellet Machine): A key part of the roller assembly, used for biomass pellet forming. Made of wear-resistant materials, it has strong impact resistance, fits various biomass raw materials, ensures uniform pressure transmission, reduces wear, and extends the service life of the roller assembly.
