FIELD: process engineering.SUBSTANCE: invention relates to woodwork, particularly, to production of composites, for example, wood boards. First, bark if separated from chips wood. Then chips are dried to form the ply of chips. Then, ply of ships is conveyed and compressed. Bark separation from wood is performed in two steps. At first step, bark major inclusions are separated after chips ply compression. At second step, final separation of bark is carried out at vibrating screens with balls. Chips ply compression pressure, amplitude and frequency of screens vibration is adjusted subject to ash content of chips.EFFECT: higher quality of chips.1 tbl |
