A METHOD AND EQUIPMENT FOR MANUFACTURING PREDETERMINED LOW BARK CONTENT WOOD CHIPS AND A HIGH BARK CONTENT FUEL FRACTION FROM WOOD CHIPS WITH BARK ATTACHED

摘要

Object of the invention is a kind of method that scheduled low bark content sawdust of device fabrication and high bark content fuel fraction are attached from sawdust and bark, including with the next stage: mechanical exfoliation handles (7), and wherein bark is reduced from chip and their size; It is connected with the chip flow of precleaning (6,9,11) with bark; With the aforementioned wood chip of final cleaning from prerinse, by means of optical separator (10). The chip of (7) thin part is screened the sawdust of outflow before mechanical exfoliation technique, then passes around mechanical process (7), and the size for improving yield rate and workpiece is distributed.
