Definitions

  • the present invention relates to a fines separator of a spiral or screw conveyor used for transferring fuel pellets.
  • Fines among pellets cause problems in feeding apparatuses by blocking up a spiral or screw conveyor and making burner ends dirty during pellet burning and increasing particulate emissions along with flue gases into the environment. It is known to cleanse and sort grain by means of a screen mounted in the screw conveyor. These screens are made of two similar perforated parts with semi-circular cross-sections, the edges of which comprise folds in the longitudinal direction for bolt tightening. The use of such a screen for separating fines of the pellets causes a problem that the fines of the pellets are accumulated in a slot at the fastening point and thus block up the conveyor. Furthermore, the need for collecting the separated fines and dust as a closed system has not been taken into account in grain cleansing screens. Thus, they are not suitable for separating fines of fuel pellets.
  • the holes of the perforated tube 1 may vary in shape and size and the dust-proof casing 3 may be split in the longitudinal direction.
