Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

As shown in fig. 3, the ball mill lining plate with the peak biasing lining provided by the embodiment comprises a lining plate body 1, the lining plate body 1 is fixedly connected with the inner wall of the ball mill, for example, the lining plate body 1 can be fixedly connected with the inner wall of the ball mill through a bolt, a connecting through hole is particularly formed in the lining plate body 1, and a threaded hole matched with the inner wall of the ball mill is formed in the inner wall of the ball mill, so that the lining plate body 1 can be fixedly connected with the inner wall of the ball mill, other fixing connection modes can be adopted, and the lining plate is not required to be elaborated.

One side of the lining plate body 1 is provided with an installation surface 2, the installation surface 2 is of a cambered surface structure matched with the inner wall of the ball mill, the radian of the installation surface 2 is determined according to the radian of the inner wall of the ball mill, the installation surface 2 with different radians can be made according to ball mills of different models, and specific limitation is not made here.

The opposite side of welt body 1 is working face 3, working face 3 is the wave form curved surface structure, be equipped with a crest 4 on the working face 3, crest 4 both sides are asymmetric structure, along ball mill direction of rotation, crest 4 is located the front side of 2 central lines of installation face, according to ball mill direction of rotation, through staggering the position of crest 4 on welt body 1, makes crest 4 be located the most serious place of wearing and tearing on welt body 1 to remedy the congenital deficiency on the product design, reached the maximize of welt body 1 service function, thereby made the wearing and tearing of welt body 1 more balanced.

At the same time, wear-resistant filler blocks 5 are embedded in the lining plate body 1. Through embedding wear-resisting filler block 5 in the welt body 1 that has now shocking resistance, lean on the welt body 1 that has shocked resistance to do the support, guarantee that whole welt is not broken, wear-resisting piece 5 plays the effect of interior chill again simultaneously, has improved the compactedness of welt body 1, has improved the wear resistance of base member. Lean on high wear resistant wear-resisting filler block 5, increased more wear resistant hard spot, improved the wearability, 1 material of welt body can adopt high manganese steel, and is specific 1 material of welt body also can adopt other materials of shocking resistance, 5 materials of wear resistant filler block adopt high chromium alloy, the same reason wear resistant filler block 5 also can adopt other wear resistant material.

The utility model can make up the wear imbalance caused by the shortage of the original lining plate inherent structural design; on the other hand, the defects of impact resistance, wear resistance and impact resistance of the lining plate on the market due to the single material can be overcome.

As shown in fig. 3 and 4, the wear-resistant pad 5 includes a plurality of connecting ribs 51 and a plurality of vertical plate ribs 52, the connecting ribs 51 are disposed at the bottom of the vertical plate ribs 52 at intervals along the length direction of the vertical plate ribs 52, and the connecting ribs 51 are fixedly connected with the vertical plate ribs 52. The specific number of the connecting ribs 51 may be determined according to the length of the stud rib 52, and is not particularly limited herein. Further, a plurality of combining through holes 53 are formed in each of the stud ribs 51.

When the lining plate body 1 and the wear-resistant filler blocks 5 are embedded and poured, firstly, the wear-resistant filler blocks 5 are cast and molded according to required sizes, then the wear-resistant filler blocks 5 are placed in a cavity of the cast lining plate body 1, then, casting materials required by the lining plate body 1 are poured, and cooling and molding are carried out, wherein the lining plate body 1 is used on a ball mill and is used for protecting a ball mill cylinder on one hand; on the other hand, the main function is that when the lining plate body 1 rotates, the lining plate drags the grinding balls in the ball grinder to throw, smash and roll the materials in the lining plate. Therefore, it must be ensured that the lining plate body 1 cannot be broken! And this kind of structure, wear-resisting filler block 5 is on wear-resisting and unbroken welt body 1 relatively speaking, more wear-resisting "hard spot" has been increased, to a certain extent, the impact resistance of original welt body 1 has been destroyed, consequently as preferred, can be equipped with a plurality of combination through-holes 53 on vertical plate muscle 52, combination through-hole 53 through setting up, make welt body 1 incompletely separate, when secondary pouring or package are cast, can pour into the material of welt body 1 in the combination through-hole 53, thereby make the whole organism of welt body 1 be connected inseparabler through combination through-hole 53 and wear-resisting filler block 5, also can: the novel lining plate has the advantages that the abrasion resistance is improved, and the original toughness is not sacrificed.

Preferably, as shown in fig. 3, the stud 52 includes a first stud 521 vertically disposed, a second stud 522 located on the left side of the first stud and inclined to the left, and a third stud 523 located on the right side of the first stud and inclined to the right, and the center line of the first stud 521 coincides with the center line of the peak 4, that is, a stud is embedded in the center line of the peak 4, so that the wear resistance of the peak 4 is improved.

Further, the included angle between the second stud rib 522 and the third stud rib 523 can be set to be α, the included angle of the cross section of the working surface is β, so that α is β, that is, the included angle between the second stud rib 522 and the third stud rib 523 is equal to the included angle of the cross section of the working surface.

In order to improve the overall strength and the service life, through research and repeated experiments, the relational expressions of 0.6H > B > 0.3H, 0.5H > 0.3H, H is the minimum thickness of the cross section of the lining plate body, H is the thickness of the connecting rib, and B is the thickness of the stud rib, and specific numbers can be determined according to the size of the lining plate body 1, for example, the minimum thickness H of the cross section of the lining plate body can be set to be 25mm, the thickness of the stud rib can be set to be 11mm, the thickness of the connecting rib can be set to be 10mm, and the like, which are not given as examples.

The present invention is not limited to the above-mentioned examples, and various modifications and changes which can be made by those skilled in the art without creative efforts are protected by the present patent within the scope defined by the claims of the present invention.
