Definitions

  • the invention relates to a method and apparatus for providing a wall, particularly the wall of a drum or tube mill, chute, screen or truck platform with a lining consisting of one or more plates or rods of wear-resistant material, particularly elastomeric material.
  • Characteristic of the invention is that anchoring elements of suitable material, preferably metal, are anchored to the wall at spaced intervals by means of fastening devices provided on or in the wall. Connecting strips are then attached to the anchoring elements and a lining is attached to the connecting strips.
  • the invention thus makes it possible to have the anchorage points on the wall independent of those between the lining plates or rods and the anchoring elements so that one has a free choice, within broad limits, of localizing these different anchorage points and can arrange them in the most suitable manner with regard to the wall construction and the lining plates or rods, respectively.
  • FIGS. 1 and 2 are a longitudinal and transverse section, respectively, of a drum mill which has been partly equipped with anchoring elements and connecting elements for the fixation of a wear-resistant lining;
  • FIG. 3 is a partial transverse section of a mill wall having mounted thereon.
  • FIGS. 1 and 2 A drum mill is illustrated in FIGS. 1 and 2.
  • the circumferential wall 1 and end walls 2 of the mill are provided with a great many holes or first fastening means at a first predetermined spacing with respect to each other which earlier served to mount a lining having corresponding fastening means at the first predetermined spacing. It is now desired to mount a lining on the drum having fastening means spaced with respect to each other at a spacing different than the first predetermined spacing.
  • the holes are arranged in three circular rows on the circumferential mill wall 1 and in two circular rows on each end wall 2.
  • the holes are not arranged in a suitable number and in suitable positions for a direct fixation of the new type of lining to be built into the mill. To avoid making new holes in other positions the new type of lining is mounted in the following manner.
  • An annular anchoring element 3--5 of strip material, preferably metal, is manufactured for each circular row of holes in the walls 1, 2.
  • Each annular member can be made in several sections to facilitate insertion thereof into the mill chamber.
  • the anchoring strips 3-5 are provided with suitable fastening means for engagement of each fastening means in the existing holes in one row of such holes in the walls 1, 2.
  • These fastening means are shown in FIGS. 1 and 2 in the form of stud bolts 6 attached to the strips 3-5 and traversing the holes in the walls 1, 2. At the outer ends the stud bolts carry nuts 7. Lining plates or rods can then be fastened in a suitable manner by the intermediary of connecting elements. At the top and to the left in FIG. 1 and at the top in FIG.
  • connecting elements are shown in the form of strips 8 and 9 which extend at angles to the longitudinal directions of the anchoring elements 3-5.
  • the connecting elements 8, 9 can be fastened to the anchoring elements 35 by welding, adhesive bonding, with the aid of screwsor bolts or fastening pins which are driven into the anchoring elements 35 by bolt setting gun, and lining plates or rodscan then be attached to said connecting elements in a suitable manner to be described in the following.
  • the connecting elements arespaced-with a second predetermined spacing with respect to eachother which is different from the first predetermined spacing which the holes in wall 1 have. Lining elements which have fastening means spaced at said second predetermined spacing can then be attached to the connecting elements.
  • FIG. 3 shows the circumferential wall 1 of the mill, an annular anchoring element 3 and strip-shaped connecting elements 8.
  • a stud bolt 6 which traverses a hole in the circumferential mill wall 1 and at the outer end has a nut 7 for clamping the anchoring element against the wall 1.
  • the connecting elements 8 are welded to the anchoring element 3 so that they overlie anchoring elements 3.
  • Lining plates 10 of elastomeric material are bonded to the connecting elements 8 by a suitable adhesive.
  • the plates 10 have fastening means (shown as grooves) for accommodating the connecting elements 8, the plates can also be bonded to the anchoring element 3.
  • Bonded over the joint between the plates 10 is a rib 11 which serves as a lifter in the mill. Such lifter ribs 11 can also be bonded to the plates 10 between the joints thereof, as shown to the right in FIG. 3.
  • the lining plates or rods and the lifters can be made from a suitable wear-resistant material, preferably elastomeric material or manganese steel.
  • a suitable wear-resistant material preferably elastomeric material or manganese steel.
  • anchoring elements 3-5 in the manner described as continuous strips which extend past a plurality of anchoring holes in the mill wall they can be formed as individual plates or like members each of which is fastened merely with the aid of one or a few fastening means to the mill wall.
  • At least one anchoring strip attached to said wall by means of said first fastening means
