Definitions

  • My present invention relates to improvements in feeding attachments for flour-mill roll frames.
  • Known feeding attachments generally have the disadvantage that the goods to be ground have to regulate or control the opening of the feed segment through a feeler and a lever system. Often a special attachment is provided for directing the goods from the feed segment into the grinding gap.
  • the present invention discloses a much more simple construction in which the goods to be ground control the feed gap directly and which also comprises means for directing the goods into the grinding gap.
  • the feeding attachment disclosed by the invention is characterized by a movable shut-off wall of which the lower portion together with a feeding roll forms a feed gap.
  • the feed gap under the influence of the goods which press against said wall, is variable in size by turning said wall about an axis which is parallel to and lower than that of the feeding roll.
  • This feeding attachment is further characterized by a baflie for directing the goods from the feed gap into the grinding gap, which baffle is disposed downstream of the feed gap and is secured to the lower portion of the shut-ofl wall.
  • FIG. 1 is a section at right angles to the grinding rolls
  • FIG. 2 shows a detail of FIG. 1 in direction of the arrow 11 in FIG. 1
  • FIGS. 3 and 4 each show a modification of certain parts of the mechanism shown in FIG. 1.
  • the housing 1 of the roll frame or stand contains two grinding rolls 2, 3 which form a grinding gap 4.
  • the goods to be ground are fed into gap 4 by a feeding roll 6 disposed in the lower portion of a feed chamber 7.
  • the latter is defined on one side by a fixed rear wall 8 and, on the other side, by a movable shut-off wall 9 which is provided with supporting and reinforcing ribs 10.
  • the lower portion of wall 9 together with feeding roll 6, forms a feed gap 12.
  • the feed gap opening is variable by turning wall 9 about an axle pin 14 which is parallel to the axis of roll 6 and lower than gap 12.
  • a bafiie 15 is secured at 16 to the lower portion of wall 9 for directing the goods into gap 4.
  • Baflie 15 is shaped so that in all of its operative positions its spacing from roll 6 increases in the direction towards gap 4. This arrangement avoids the goods flowing under baffle 15 exerting an upward pressure on wall 9, as the latters position only should depend on the goods in chamber 7.
  • Wall 9 and baflie 15 form a sharp edge 16 of which the spacing from roll 6 defines gap 12. In all of its operating positions, edge 16 is closer to the surface of roll 6 than is any other point on baffle 15. Hence, the flowing goods could not interfere with the adjustment of wall 9.
  • a regulating means which comprises two arms 19, 20 pivoted on a pin 22 to a hanger 21 fixed to housing 1.
  • Arm 19 carries a roller 24 which presses against the upper portion of one of the ribs 10.
  • On a threaded portion 26 of arm 20 is movably mounted a weight 27.
  • Arm 20 further carries a piece 28 traversed by a screw 29 for transmitting the turning moment of weight 27 onto arm 19.
  • baffle 61 is pivoted to wall 9, its position being controllable by a screw 32 and being maintained with the aid of a spring 33. In operation, the direction of baffle 31 may thus be regulated.
  • the sensitivity of the attachment disclosed should be raised. This is done by shifting the center of gravity of wall 9 and the the parts secured thereto behind axle pin 14 or rather downstream thereof. The goods then do not have to do any work for adjusting the Wall 9, since the latters center of gravity does not have to be raised.
  • a mechanism for regulating the center of gravity of Wall 9 is shown in the modification of FIG. 4.
  • a weight 36 is movably mounted on a threaded bar 35 attached to wall 9. By adjusting weight 36 on bar 35, the center of gravity of wall 9 may be controlled.
  • the device of FIG. 1 may be regulated to effectively control the flow of low bulk materials.
  • a feeding attachment on flour-mill roll frames having grinding rolls, a feed roll, a movable shut-off wall, the lower portion of said movable wall together with said feed roll forming a feed gap of which the width under the action of the goods to be ground pressing against said wall is variable by turning said Wall about an axis which is parallel to the feed roll and lower than the feed gap to increase the width of said feed gap in proportion to the weight of good pressing against said movable wall, and a bafile for directing said goods which have passed through said feed gap into the grinding rolls, said baflle being disposed downstream of the feed gap and being mounted on the lower portion of said Wall.
  • shut-01f Wall and the baflie form a sharp edge the spacing of which from the feed roll defines the feed-gap width.
