Title: Method and apparatus for controlling the interior contour of a tumbling mill
IPC: B02C17/22
Filed: 1963-08-28
Abstract: 999,521. Grinding mills. HARDINGE CO. Inc. Aug. 28, 1963 [Sept. 17, 1962], No. 34007/63. Heading B2A. An autogenous or ball mill includes a shell supported for rotation on trunnions 16, 18, Fig. 1, and lining means connected to the interior of the shell and comprising elements of relatively high, medium and low heights detachably arranged around the interior surface of the mill so as to permit adjustment of the inner contour of the mill, by replacement of elements to compensate for wear. As described, the aforesaid lining elements are provided both on the inner periphery and conical ends of the mill. Liner segments 24 are bolted adjacent the conical end 12, the edges being shaped to receive the bolted radial wedge and lifter bars 26, 28 of successively greater height. The peripheral portion 10 of the shell has curved liner segments 30, 32 with inner surfaces sloping towards each other. Medium and high wedge and lifter bars 34, 36, respectively, extend between the edges of the liner segments 30, 32, and are bolted by wedge bolts 38, and spaced as in Fig. 5. Grate sections 40 are bolted at the exit end and circumferentially spaced to receive the radial lifter bar sections 42, 44 also of successively greater heights. A space 48 receives material discharged through openings in the grates, and lifter blades 50 in the space carry material upwards until it falls under gravity against the conical end 52 of the mill and is discharged through an exit cone 22. Deflecting rings 54, 56 effect transverse movement of material axially within the mill. When a medium height bar 34<SP>1</SP>, Fig. 7, becomes worn, the high bars 36<SP>1</SP> have worn down to medium height and the bar 34<SP>1</SP> is then replaced by a high bar, so as to preserve a similar contour in the mill. Thus alternate medium and high bars are progressively changed in position around the mill with each replacement. In a modification, the grate is spaced at its periphery from the interior of the peripheral portion of the mill and an additional deflecting ring protects the grate from excessive abrasion. A further embodiment employs a cylindrical casing with liner segments extending between opposite ends of the mill, and alternate longitudinally extending high and medium height lifter bars, which may also be provided at the ends of the mill. The lifter bars may be of two-part construction, comprising wedge portions and upper portions, secured by wedge bolts extending through both portions as well as the shell plate ; as wear occurs, the upper portions only are replaced. In a further embodiment, the liner segments are flanged so that flanges 88, Fig. 9, on successive segments are receivable in recesses 90 formed along opposite sides of the lifter bars 92, 94. By clamping the segments 86 relative to the shell, the bars 92, 94 are operatively secured. In a still further modification, liner and lifting sections 106, 110, 108 of successively greater heights are provided as shown in Fig. 11. Specification 949,791 is referred to.

Abstract: 759,458. Firearms. OLIN MATHIESON CHEMICAL CORPORATION. Nov. 25, 1954 [Jan. 6, 1954], No. 34176/54. Class 119 [Also in Group XXII] In a firearm, the forward portion of the cartridge chamber is lined with a, gas pervious material 18, e.g. sintered metal, which is held in position by a gas impervious liner 19 at the breech end. This arrangement permits equalization of gas pressure inside and outside the cartridge case to prevent deformation of the case and facilitate its extraction. The surface of the liner-receiving cavity 17 or the outer surface of the liner 18 may be fluted to facilitate dissipation of the explosion gases. A tubular member 26 in the liner 18 surrounds the forward lip of the cartridge case to prevent undue lip deformation into the gas pervious material. The liner 18 may be formed in longitudinal arc sections for easy insertion in the cavity 17. The gas pervious material may comprise sintered steel, stellite alloys, molybdenum and ceramic-metallic combinations and should be pervious to the extent of permitting gas under pressure of about 200 pounds per square inch and above to flow through it with only slight difficulty.
