The obtained fraction of the chip has a size of from 3 to 7 mm, depending on the structure, can be used as additional raw materials for the timber industry in the production of particleboard, or thermally recycled in combustion systems. The final particle size of wood chips at the output depends on the size of the holes of the set of sieves. With the installation of a system of sieves it is possible to achieve separation of wood chips fractions. The grinders can be set magnetic drive roll unloading conveyor to partially separate the metal inclusions.
