Pellet press is a machine used to produce pellets from wood waste materials. Unlike feed pellet machines, this type of pellet machine features a disc mounted on a vertical shaft. Depending on the material to be compressed, three or four rollers rotate at a specific speed on the disc, performing the compression process. The hole diameter and design of the disc are made from special alloy steel according to the desired pellet size and diameter. This results in a long-lasting pellet press machine.
