Abstract

The utility model discloses a self fixed bimetallic compound lining tile for a ball mill. An arched lining tile, an expansion plate, a pre-stress plate and a bolt pin are inlaid on the inner side of the barrel body of the ball mill by an arched supporting principle so that the lining tile doesn't fall off under the self fixed action of the pre-stress plate and the fixed locking action of the integral intensification, and the utility model reduces the vibration and the noise of the ball mill and alleviates the fatigue damage of the lining tile. Due to the arched self fixed installing mode, the utility model solves phenomena that the ball mill leaks powder and a wedge block is fallen off and broken.

Description

From solid type bimetallic composite balls grinding machine lining tile

The utility model discloses a kind of type bimetallic composite balls grinding machine lining tile of consolidating certainly, relate to ball mill lining tile technical field.

Traditional ball mill lining tile is to utilize fixed wedge, dog wedge and bolt that lining tile is fixed on the ball mill barrel, material is the Mn steel, bolt, voussoir frangibility come off in use, cooperation damping property between the lining tile is poor, mix simultaneously along with phenomenons such as dust leakage, noise expansion take place, thereby cause repairing frequent, the equipment that influences normally moves, and causes very big economic loss to producer.

Task of the present utility model provides a kind of from consolidating type bimetallic composite balls grinding machine lining tile, has overcome the generation that traditional ball mill lining tile comes off, leaks phenomenons such as powder.

For finishing above-mentioned task, the utility model adopts following solution: it is by some lining tiles, distensible plate, pin and give stress plate and constitute, utilize the arch form support concept, lining tile is designed to the arch bulk, be set into one with ball mill barrel, the arch circular arc radial end face of lining tile adapts with the reticule of cylindrical shell and cooperates, distensible plate is a fillet bulk, its back side shape matches with the radian of cylindrical shell, axially has certain oblique angle, consolidation lining tile when being used to assemble, and both sides have concave groove and match with pin and be connected along cylindrical shell, prestressed slab is that sheet is consistent with the radial end face shape of lining tile, can make the flexible riveted joint of lining tile.In addition, for the wearability that improves lining tile possesses good plasticity and toughness again, lining tile is designed to the layer structure of the material of working face and two kinds of different performances of non-working surface.

Because the assembling pattern of lining tile is domes, lining tile must lean on certain physical dimension just can guarantee it is not fallen down, therefore the interior outer arc difference of lining tile thickness direction must reach certain value, and arc is a kind of from type bimetallic composite balls grinding machine lining tile difference computing formula is as follows admittedly:

H is the radial edges thickness of lining tile. S=2πh/n

N is the piece number of the every circle lining tile of ball mill barrel.

The π value is 3.14.

Good effect of the present utility model is: functional part such as adopt that arch support structures and distensible plate, prestressed slab, pin are fastened, can make lining tile ongoing from not coming off under effect and the whole solid lock effect of strengthening admittedly at prestressed slab, and vibrations and shock wave have been weakened, alleviated the fatigue damage of lining tile, its noise is reduced.Because the mounting means of lining tile is " non-bolt " form, avoided bolt looseness, fracture, voussoir to come off and the generation of ball mill leakage powder phenomenon.

Fig. 1 is the utility model structure principle chart.

Fig. 2 is the utility model lining tile structural representation.

Further narrate the utility model below in conjunction with accompanying drawing: in Fig. 1, the lining tile 1 of arch form, distensible plate 2, prestressed slab 3 and pin 4 alternate combination-inlayings are on the inner ring of cylindrical shell 5, rivet by giving stress plate 3 between the lining tile 1, per seven lining tiles 1 are one group, accompany distensible plate 2 between every group and be located by connecting by pin 5, in actual applications, with reference to Fig. 2, lining tile 1 is working face 6 and 7 two layer structures of non-working surface, working face 6 can be made by high chromium cast iron material for undaform, non-working surface 7 is the ordinary carbon steel manufacturing, and the more traditional manganese steel lining tile of anti-wear performance of the two kinds of compound back of material lining tiles improves 3 times, and while lining tile integral body has good plasticity and toughness again makes it shock-resistant.

Claims
