Definitions

  • the present invention relates to shredders comprising an annular track with an axis horizontal, a roller capable of rolling on said track, means for pressing the roller on the track and means for moving the material from one edge to the other of the track, so that it passes under the roller several times before being evacuated.
  • the mill object of the present invention is characterized in that the spacing between the roller and the track decreases from the edge of the track located on the feed side material to be ground up to a distance from this edge at least equal to 80% of the width of the track, and then grows faster to form a decompression zone on the side of the evacuation of the ground material.
  • the crusher shown in the drawings consists of a drum 10, with a horizontal axis, which is supported by pads 12 allowing its rotation about its axis; these skates could be replaced by a bearing or rollers.
  • the drum is rotated by conventional means, not shown, for example by a motor and a reduction gear, the output shaft carries a pinion engaged with a ring gear fixed on the drum.
  • the track is formed of three surfaces frustoconical 14a, 14b and 14c joined so that its diameter decreases, in the direction of progression of the material indicated by the arrow, over most of its width and then increases quickly in its last part.
  • the angle at the top of the surface 14a is greater than that of the surface 14b.
  • the surface 14c of the track and the roller define the area of decompression. In the plane of the figure, which contains the axes of the roller and the track, the angle ⁇ formed by this part of the track and the roller is less than 50 °.
  • the surface of the roller 16 is cylindrical and its axis is parallel to that of the track.
