Definitions

  • My invention relates to improvements in delivery-clearing devices on roller-mills for grain and seeds, and the main object of my improvement is to prevent the goods from leaving the crushing gap in the form of small laminae and from sticking in patches to the rollers after having passed through the crushing-gap.
  • a number of delivery clearing-devices on roller-mills have become known in the prior art, which devices aim to break up or disintegrate the patches of goods sticking to the rollers when grinding parts of various grains and seeds.
  • the ground goods in such prior devices either are collected in greater quantities, after having passed the rollers, by means of special arrangements, or the said devices are built with a view of subdividing the ground goods, upon delivery from the crushing-gap, into two fine streams without collecting the goods.
  • relatively large rubbing-faces are set up between the rollers and the goods, whereby not only much grindingfiour or dust is produced, but also the rollers and the goods are excessively heated.
  • FIG. 1 is a cross-sectional view through the rollers and a clearing-device on line 1-1 of Fig. 2, and
  • Fig. 2 a diagonal section on line II-II of Fig. 1.
  • the grinding-rollers of a conventional rollermill are designated by I and 2, and the goods 3 are ground intermediate thereof.
  • a mill beam 5 is disposed back of the crushing-gap 4 and is from 3 to 15 millimeters thick, thus forming a relatively small collecting-space 6 for the ground goods. The latter is detained in said space, and
  • the tension of spring I4 may be regulated.
  • the latter tends to pull bell-crank lever I0 up against two stopscrews I6 (one at each end of the mill frame) which are so set that the edges of beam 5 adjacent the rollers I, 2 are equally spaced over their entire length, from the said rollers, thus affording substantially equal delivery-gaps for the goodsstreams I and 8.
  • the ground goods in the collection space 6 are detained to such extent only as to remain loose and to be continuously replenished in operation.
  • a device on roller-mills for grains and seeds adapted to prevent the goods from leaving the crushing gap in the shape of small laminas and from sticking in patches to the rollers, comprising a mill beam loosely mounted to the rear of the crushing-gap between the rollers and extending over the entire length of the latter, the forward edge of said beam projecting upwardly into said gap so as to leave a comparatively small space between said gap and rollers and a delivery-gap on each flank of said edge between the rear end of said space and said rollers, springloaded rockable abutting-means for the two lateral rear ends of said beam, a set-screw at each lateral end of said beam for freely supporting the latter on its Web, and an adjustable stopscrew acting on each said abutting-means for adjusting the throw of the latter; the whole in such combination as to permit to detain the ground goods in the said space in loose condition and to continuously replenish same in operation.
