Designed specifically for the MZLH420 pellet mill, this roller shell delivers superior performance when processing high-fiber raw materials such as sawdust, wood chips, and forestry by-products.
By lowering surface pressure on the ring die, it improves pellet forming efficiency while significantly reducing equipment abrasion, making it a cost-effective choice for long-term biomass pellet production.





1.Optimized pressure control for high-fiber and low-fluidity materials
2.Long operational lifespan with stable pellet yield
3.High-strength alloy steel construction for demanding industrial conditions
4.Optional customized aperture sizes based on raw material characteristics
5.Consistent pore smoothness for reduced energy consumption
