ABSTRACT:
A feeding device is disclosed for feeding cellulose material, such as wood chips to gas swept size reduction machines, and wherein the elimination of foreign particles from the material to be crushed is mainly achieved by pneumatic screening. The device includes a screening passage into which widely spread input material trickles slowly over a slide, having an angle of inclination .beta. which is slightly greater than a friction-angle whose value is determined from its surface roughness. The screening passage is impacted by an air current generated by a cross current fan and which is directed, along a channel, roughly tangentially onto a guiding wall. The guiding wall is arranged at an angle of inclination .gamma., selected so that the guiding wall functions as a pneumatic sorting table, and where it forms with the channel a discharge slit for the foreign particles. The lateral spread of the input material is accomplished in the upper area of the feeding device by cascading surfaces which are arranged at an angle of inclination .alpha., and which are covered with fine mesh screens to eliminate foreign particles of such a fine grain that they may not be effectively pneumatically screened.
