Definitions

  • This invention relates to improvements in a liner with which the inner surface of the barrel of a rod mill, ball mill or the like is lined, and more particularly to improvements in a cushioning material for such a liner.
  • rubber is adhered to the inner surface of the barrel of a rod mill, ball mill or the like to secure the contacting surface of a liner and cushion the effect of the impact load to which the barrel is subjected.
  • a liner with a cushioning-according to the invention is characterized in that a cushioning material of high compression strength and small expansion is positioned on, more especially attached to, the back surface of the liner.
  • small expansion is meant small strain at the elastic limit.
  • a mill liner with a cushioning according to the invention to the back surface of which a cushioning material of high compression strength and small expansion is attached, never stretches or is broken even when the cushioning is subjected to heavy impact load, and hence the liner bolts never become loose or broken.
  • a mill liner according to the invention is advantageous in that the liner can be retained securely, and in.that maintenance is reduced because retightening of the liner bolts is unnecessary.
  • Fig. 1 is a schematic cross sectional view of a rod mill 1
  • the reference numeral 2 represents a barrel, 3 a mill liner with which the inner peripheral surface of the barrel 2 is lined, 4 an outlet port, and 5 a trunnion the inner surface of which is lined with a liner 6.
  • a cushioning material of high compression strength and small expansion for example, an asbestos sheet 7.
  • This asbestos sheet 7 is provided on the entire back surface except on upper and lower recessed portions 8 of the liner 3 and bolt holes 9.
  • the bolt holes 9 are opened to notches 11 which are formed on both the axial ends of the lifter 10 of the mill liner 3.
  • a mill liner incorporating a cushioning having the above-described structure is mounted on the inner peripheral surface of the barrel 2.
  • the bolt hole 9 of the mill liner 3 and the bolt hole 12 of the barrel are brought into alignment and a bolt 13 is inserted into these holes 12, 13 from the inside of the barrel 2 such as to penetrate through the barrel 2.
  • the mill liner 3 is fixed by tightening a nut 15 which is placed over the threaded portion of the bolt 13 which projects on the outer side of the barrel 2 through a washer 14.
  • the mill liner 3 for the barrel 2 never stretches or is broken even when subjected to a heavy impact load. Accordingly, the bolt 13 which clamps the mill liner 3 never comes loose nor is broken.
  • a hard rubber sheet having a Shore hardness of over 60 (H s > 60, ' JIS A) may be used in place of the asbestos sheet.
  • the cushioning material of high compression strength and small expansion for use in the invention preferably has a compression Strength of 500 kg/cm 2 or more.
  • the strain at elastic limit of the cushioning material is preferably 20 per cent or less.
