Definitions

  • This invention relates to a lining of rubber adapted to protect rotary drums such as ball mills or tube mills or the like comprising a plurality of adjacent sections constituting partly separate lifting means (so-cflled lifters) and partly separate lining plates disposed between the said lifting means.
  • a wear lining of steel comprising a plurality of adjacent sections consisting partly of separate lifting means (so-called lifters) and partly of separate lining plat-es disposed between the said lifters are previously described in Swiss patent specification 272,033.
  • This lining type has been in use for many years, but it shows several serious drawbacks. It is, for example, very heavy, wears rela tively quickly and includes serious risk when being mounted.
  • the invention is characterized in that the lifting means are provided with an internal longitudinal slot with means, for example bars with threaded pins welded thereon, inserted or vulcanized therein for holding the lifting means.
  • the sections are preferably arranged along the generatrices in the drums, and the rubber lining plates along their longitudinal edges provided with recesses, the lifting means preferably being provided with corresponding profile.
  • the said lifting means are anchored in the wall of the drum.
  • the holding or anchoring occurs in such a manner that there is produced a pressure against the recesses of the rubber lining plates, with the result, that the lifting means act as locking means for the plates. There is no objection to anchor even the plates in the wall of the drum, but this is unnecessary if there is normal distance between the lifting means.
  • the means for holding the lifting means comprise preferably bars with threaded pins welded thereon.
  • holding means may be mentioned bars with threaded holes or sleeves adapted to screw bolts therein from the outsideof the Whilst the lining is being mounted.
  • the bars may have the same length as the lifting means or be divided in several sections.
  • the lifters in order to have the desired effect for grinding in the mill, must be given a certain height above the rubber lining plates, which plates, in their turn, must have a certain, rather considerable thickness.
  • Preferable thicknesses are 40-80
  • the relation between the thickness of the rubber lining plates and the distance between the highest point of the lifting means and the inside of the sheet casing should be between 0.25 and 0.95, preferably between 0.50 and 0.70.
  • the said values cannot be considered to be critical but should be regarded primarily as suitable.
  • the height above the plates which the lifters should have from the beginning depends on several factors, for example on the distance between the lifters, the grinding volume etc.
  • the sections of Wear-resistant material are preferably made of unreinforced natural rubber with a hardness of 40-80 Shore and with high rubberycontent.
  • the manufacture of the lifters is preferably carried out by extrusion or compression moulding.
  • the lifters need not necessarily be made in one piece but may be jointed while being mounted. In this case it is preferable to insert sealing means, preferably of unreinforced soft rubber hose.
  • the joints of two adjacent parallel lifters should be staggered in relation to one another. Sealing elements may possibly be inserted between the rubber lining plates.
  • the rubber lining plates may be made of more or less entirely covering material.
  • the lifting means may in such a case be arranged above the material or in recesses cut into the upper surface of the material.
  • Such a lining renders greater difiiculties in mounting due to the larger rubber fabric, but it may include advantage-s due to a simpler replacement of the lifting means.
  • FIG. 1 shows in a schematic manner the cross-section of a mill
  • FIG. 2 is an elevation partly in section on line II of FIG. 1
  • FIG. 3 is an enlarged cross section of a detail of a lifting means
  • FIG. 4 is an enlarged cross sectional view of a detail of another embodiment of the lining according to the invention
  • FIG. 5 is an enlarged cross sectional view of a sealing element between two end surfaces of a lifting means in several parts.
  • FIG. 1 shows in a schematica-l manner how the mill drum 1 is lined with lining plates of rubber 2, and lifting means 3.
  • FIG. 2 is a side view partially in section along the line II-II in FIG. 1 andshows how the lining is divided in sections disposed along generatrices in the circular drum.
  • FIG. 3 shows an example of how the rubber lining plates 2 are provided with recesses along their longitudinal edges.
  • the lifters 3 are provided with corresponding profiles in such a manner, that the lifters act as locking means for the plates 2.
  • the lifters 3 are provided with grooves or 5 7 wedded thereon which protrude through openings in drum 1 and are engaged by nuts 7a.
  • FIG. 4 shows another embodiment with entirel covering rubber lining plate 8 including grooves 9 wherein the lifters 10 ane arranged.
  • the bars 11 attached to lifters 10 by vulcanizing are utilized with internally threaded sleeves 1'2 welded thereon.
  • FIG. shows in a schematic manner how sealing elements 12 are used in the joints between two end surfaces of a lifter divided in two par-ts 13a and 1312.
  • the calculated minimum time of 18,000 hours is based on the replacement of the lifters when they are worn to half their height. Thereby, only the lifters have to be replaced.
  • the wear lining according to Swiss patent specification 272,033 it was, however, necessary to exchange both the lifters and the lining plates already after 7,000 hours.
  • the mounting of the wear lining according to the present invention was simple and substantially without risk, while the mounting of new wear lining in the other mill was time wasting and particularly full of for the Workers.
  • Wear lining of rubber for rotary drums comprising a plurality of adjacent sections of separate rubber lifting means and separate rubber lining plates disposed between the said lifting means, the said lifting means being provided with an internal slot having bars inserted therein, said bars having threaded pins Welded thereon for holding the lifting means.
  • Wear lining of rubber for rotary drums comprising a plurality of adjacent sections of separate rubber lifting means and separate rubber lining plates disposed between the said lifting means, the said lifting means being provided with an internal slot wherein bars having threaded holes are inserted for holding the lifting means.
  • Wear lining of rubber for rotary drums comprising a plurality of adjacent sections of separate rubber lifting means and separate rubber lining plates disposed between the said lifting means, the said lifting means each being provided with an internal slot wherein bars having threaded sleeves welded thereon are inserted for holding the lifting means.
  • Wear lining according to claim 1 characterized in that the sections are arranged along the generatr-ices in the drums.
  • Wear lining according to claim 1 and in which the ratio between the thickness of the rubber lining plates and the distance between the highest point of the lifting means and the wall of the drum is between 0.25 and 0.95, preferably between 0.50 and 0.70.
  • Wear lining according to claim 1 and in which the sections are made of lumeinforced natural rubber with a hardness of 40-80 Shore and with high rubber content.
