In pellet mill production, inconsistent pellet lengths and short, broken pellets are common. Many factors influence length, such as output: higher output results in longer pellets, and vice versa. Some manufacturers adjust the biomass pellet machine's output to achieve specific pellet length requirements. The ring die aperture does not directly affect pellet length; it, along with the number of apertures, influences length. A higher ring die aperture ratio results in shorter pellets, and vice versa.
