ローラミル
Document Type and Number:
Japanese Patent JP5756559
Kind Code:
B2
Abstract:
The invention relates to a roller mill, in particular a coal mill, with a feed system, having an integrated screw feeder. The screw feeder is arranged virtually horizontally in the region of a grit cone and comprises a screw shaft guided through the roller mill and the longitudinal axis thereof, which screw shaft is arranged on both sides respectively outside of the roller mill and at one end with a drive means and at the other end in a bearing outside of the roller mill. The feed material is fed with the screw conveyer outside of the roller mill and forcibly conveyed therein to a tray side rejection opening above a cone opening of the grit cone and drops together with the coarse grain rejected in the classifier centrally onto the grinding pan. An even distribution of the feed material and improved smooth running of the roller mill and energy saving are achieved and also soiling of the screw shaft is avoided.
