channels 7 7 u2032 into two cutting mills 8 8 u2032 in which the flat chips are cut up by means of air the cut up flat chips are then suctioned from the cutting mills 8 8 u2032 and led into a wet cyclone 9 which separates the cut up flat chips from the air from the wet cyclone 9 the cut up flat chips are led with a pressure chain conveyor 10 into a dosing bunker 11 the dosing bunker 11 is formed as intermediate storage for a dryer 12 and is connected to the dryer 12 by means of a pressure chain conveyor 13 in this dryer the cut up flat chips are dried which is why the previously described system components are referred to with the term u201c wet side u201d and the system components described in the following are referred to with the term u201c dry side u201d the cut up flat chips are suctioned through the dryer 12 and led on the output side into a dryer bunker 15 via a pressure chain conveyor 14 the dryer bunker 15 is formed as intermediate storage for two hammer mills 16 16 u2032 which are each connected via a vibrating flat channel 17 17 u2032 and a common worm 18 to the dryer bunker 15 in the hammer mills 16 16 u2032 the cut up and dried flat chips are broken up into flat splinters the flat splinters are suctioned by means of air from the hammer mills 16 16 u2032 and led into a drying cyclone 19 in this cyclone the flat splinters are separated from the air stream from the drying cyclone 19 the flat splinters are led by.
