ABSTRACT:
Methods for processing wood chips for digestion utilize a chip destructuring apparatus. The method includes an initial disc screen for removing the gross overthick and oversized chips which are discarded or are processed through a rechipper. After the initial disc screen, the entire stream of chips is processed to eliminate tramp metal. The entire chip stream is screened to remove fines. The stream of chips is fed to the chip destructuring apparatus from a surge bin with a star feeder. The star feeder is a metering device and is operated by a controller which monitors the level of chips in the surge bin. The controller uses the star feeder to feed a steady supply of chips to the chip destructuring apparatus which allows the destructuring apparatus to be configured for a maximum feed rate.
