Definitions

  • ABSTRACT OF THE DISCLOSURE The invention aims at preventing or reducing the penetration of ground material into the gap between the lifting rib and the adjacent rubber panel, and it is important that the joint between two successive panels, when one panel overlaps the other with a lifting rib portion, cannot be widened because of the panel edge overlapped by the lifting rib portion leaving its correct position beneath the lifting rib portion under the action of the forces and deformation to which the panels are subjected during operation of the mill. This applies especially when the panel edge is clamped against the grinding chamber shell by the lifting rib portion since the clamping force, when the panel is of rubber, may create forces which tend to remove the panel edge from its correct position beneath the lifting rib portion.
  • This invention relates to an improved mill having a rotary grinding chamber with a cylindrical or substantially cylindrical boundary wall, a liner of axially directed and circumferentially successive rubber panels on the inner side of said boundary wall, and axially directed lifting ribs of rubber projecting into the grinding chamber from the inner side of said liner.
  • FIG. 1 is a diagrammatic fragmentary cross-sectional view of the grinding chamber of a mill improved in accordance with the invention
  • FIG. 2 is a fragmentary view, on a larger scale, of the mill grinding chamber shown in FIG. 1.
  • the boundary wall of the grinding chamber could also be polygonal and thus only approximately cylindrical.
  • Disposed on the inner side of the wall of the grinding chamber is a liner of axially directed and circumferentially successive rubber panels 2.
  • Each rubber panel 2 substantially is of equal thickness throughout the main portion thereof.
  • One axially directed edge portion of each panel 2 has a relatively thin flange 3 adjacent the wall '1 of the grinding chamber, said flange 3 projecting from the remaining panel 2 in the circumferential direction of the wall 1 and having at its outer end a nose 4 which is directed inwardly from said wall 1.
  • each panel 2 is formed as a lifting rib 5 integral with the panel and overlaps the adjoining edge portion of the next following panel.
  • the edge portion of each panel 2 which is to form the lifting rib 5 thus has a surface 6 facing the grinding chamber wall 1, said surface 6 overlapping and bearing against the full thickness portion of the adjoining panel 2, and from the surface 6 there extends a projection 7 towards the grinding chamber wall 1 in order to engage the flange 3 and nose 4 of the adjoining panel 2 in the manner best seen from FIG. 2.
  • each panel 2 there is formed in each panel 2 an axially directed slot 8 for accommodating a fixation bar 9 which is adapted, by means of bolts 10 and nuts 11, to press those portions of two adjoining panels 2 which are situated between the bar 9 and the wall 1 against said wall 1 for clamping the liner to the boundary wall of the grinding chamber.
  • a rotary grinding mill comprising a substantially cylindrical rotary shell defining a grinding chamber, a liner on the inner surface of said shell, comprising a plurality of rubber panels, mounted in a close series around the inner circumference of said shell, a first and a second marginal portion on each of said panels, being oppositely located on each of said panels and extending axially of said shell, a lifting rib integrally formed on said first marginal portion of each of said panels and projecting into the grinding chamber, a flange integrally formed on said second marginal portion of each of said panels, said flange being thinner than the rest of said panel and extending along the inner surface of said shell, a nose integrally formed on the free axially extending edge of said flange, said nose projecting from said flange inwardly towards the center axis of said shell, and means on said first marginal portion of each of said panels engaging said flange of an adjacent one of said panels between said nose and the rest of said adjacent panel.

  • said flange being thinner than the rest of said panel and 5 extending along the inner surface of said shell, a nose integrally formed on the free axially extending edge of said flange, said nose projecting from said flange inwardly towards the center axis of said shell, a projection on said first marginal portion of each of said panels, projecting 0 from said first marginal portion towards said shell and into engagement with said flange of an adjacent one of said panels between said nose and the rest of said adjacent panel, surface means on said first marginal portion of each of said panels and on said nose of an adjacent one of said panels, defining a slot extending axially of said shell, and
