SIEVING DEVICE FOR SOLID MATERIAL AND A METHOD FOR SIEVING SOLID MATERIAL

摘要

The aim of the invention is to provide a sure and trouble-free sieving of a solid material (R) using a sieving device (1) having an arrangement which is as simple as possible. To this end, a spiral (10) formed by a rod (8) which is wound in a helicoidal manner, or a plurality of such rods (8) are provided as a sieving device. Said rod(s) (8) can rotate around a longitudinal axis (3). For sieving, the solid material (R) is introduced into the inner space (11) formed by the rod (8), preferably with the assistance of an aligning device (2) for longitudinally extended solid material parts (16). The spirals (10) comprise, in particular, a bend so that the lodged solid materials (R) can automatically detach themselves. The sieving device (1) is especially suited for sieving pyrolysis residual material.
