In industrial biomass processing, a high-performance shredder designed for palm shells and related palm waste serves as the primary size-reduction unit that transforms bulky, irregular palm shell material into uniform, manageable fragments suitable for downstream processing. Palm shells are dense lignocellulosic residues from palm oil production that, if left unprocessed, present challenges in handling, transport, and energy conversion. A purpose-built palm shell shredder employs robust alloy steel blades and a heavy-duty rotor assembly engineered to shear and cut the hard shell structure into a controlled particle size, typically in the range of 10–30 mm, depending on rotor configuration and screen selection. This fragmentation reduces the physical size and heterogeneity of the shells, promoting consistent drying, enhanced combustion characteristics, and improved feedstock quality for pelletizing or gasification applications. The shredding stage also facilitates more uniform moisture distribution and reduces the overall load on subsequent equipment such as dryers and pellet mills.
