Abstract
The invention discloses a ball grinder liner which comprises a liner body. Mounting holes are arranged on the liner body which is formed by upper-arc protrusions and lower-arc grooves, the upper-arc protrusions and the lower-arc grooves are tangent and in end-to-end connection, and special-shaped nuts are mounted in the mounting holes and locked on bolts. The liner body is formed by the upper-arc protrusions and the lower-arc grooves which are tangent and in end-to-end connection, and the upper-arc protrusions function in buffering steel balls and materials, so that abrasion to the lower-arc grooves is reduced; when the materials flow to lower-arc grooves among the upper-arc protrusions, part of the materials remain in the grooves due to retaining effect of the protrusions, and when the materials continuing to fall continue to flow past the positions, a state that former materials beat later materials is formed, and the materials do not contact with the bottom of the liner, so that the liner is further protected, the liner has excellent abrasion resistance, and the service life of the liner is prolonged.
Description
Technical field
The present invention relates to a kind of liner plate, relate in particular to a kind of liner plate that is used in ball mill barrel, belong to the disintegrating apparatus technical field.
Background technology
Ball mill is widely used in the industries such as metallurgy, mine, building materials, electric power as a kind of common disintegrating apparatus, its operation principle is simple, adopt machine driving to make mill tube make low speed rotation, steel ball in cylinder is promoted to the 53o of horizontal sextant angle～60o left and right because of the effect of centrifugal force, be waterfall shape by the parabolic track and fall, crushing medium (ore deposit, stone, coal etc.) is worn into the graininess that needs.In the process that grinds, the steel ball liner plate that clashes, the time is slightly long, liner plate will be subject to great wearing and tearing, the wearability variation, and shorten service life, operating efficiency has also reduced greatly, changes liner plate if often stop production, and has both increased the production cost of enterprise, also reduced output, and the interior liner plate volume of installing of ball mill mill tube is large at present, and heavy uses the ball mill mill tube easily to be out of shape for a long time, dismounting and inconvenience thereof, thus the economic benefit of enterprise affected.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed that a kind of intensity is high, wearability good, the ball grinding machine lining board of long service life.
Technical solution of the present invention is achieved in that a kind of ball grinding machine lining board, comprise the liner plate body, described liner plate body is provided with installing hole, and described liner plate body is comprised of upper arc projection and lower arc fluting, described upper arc projection and lower arc fluting are tangent, and the first place joins; Be provided with abnormity nut in described installing hole; Described abnormity nut is locked on bolt.
Preferably, described abnormity nut top is square, and the bottom is taper.
Preferably, described bolt welding is on the barrel of ball mill.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of ball grinding machine lining board of the present invention, the liner plate body is connected with lower arc fluting is the first by upper arc projection, steel ball when ball mill rotates in ball mill falls from eminence and pounds to raw material, at first collide on upper arc projection, the upper arc that will first wear and tear is protruding, upper arc projection plays the effect of a buffering to steel ball, alleviated the wearing and tearing to lower arc fluting, thereby makes liner plate have good anti-wear performance; And when material flows in lower arc fluting between upper arc projection and upper arc projection; barrier effect due to projection; partial material is stayed in groove; when the material that continues to fall continues to flow through this position; formed the material dnockout and do not contacted with the bottom of liner plate; play equally the effect of protection liner plate, the service life of having improved liner plate.The present invention also has advantages of simple in structure, easy for installation, has improved the production capacity of ball mill, and certain application value is arranged.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the three-dimensional structure diagram of a kind of ball grinding machine lining board of the present invention;
Accompanying drawing 2 is the front view of a kind of ball grinding machine lining board of the present invention;

Wherein: 1, liner plate body; 2, upper arc projection; 3, lower arc fluting; 4, installing hole; 5, abnormity nut; 6, bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1,2,3 is a kind of ball grinding machine lining board of the present invention, comprise liner plate body 1, described liner plate body 1 is provided with installing hole 4, and described liner plate body 1 is comprised of upper arc projection 2 and lower arc fluting 3, tangent and the first joining between described upper arc projection 2 and lower arc fluting 3; Be provided with abnormity nut 5 in described installing hole 4;Described abnormity nut 5 tops are square, and the bottom is taper; During installation, liner plate body 1 is laid in the mill tube barrel, screw rod 6 is welded on the mill tube barrel, get final product with abnormity nut 5 is fastening.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of ball grinding machine lining board of the present invention, the liner plate body is connected with lower arc fluting is the first by upper arc projection, steel ball when ball mill rotates in ball mill falls from eminence and pounds to raw material, at first collide on upper arc projection, the upper arc that will first wear and tear is protruding, upper arc projection plays the effect of a buffering to steel ball, alleviated the wearing and tearing to lower arc fluting, thereby makes liner plate have good anti-wear performance; And when material flows in lower arc fluting between upper arc projection and upper arc projection; barrier effect due to projection; partial material is stayed in groove; when the material that continues to fall continues to flow through this position; formed the material dnockout and do not contacted with the bottom of liner plate; play equally the effect of protection liner plate, the service life of having improved liner plate.The present invention also has advantages of simple in structure, easy for installation, has improved the production capacity of ball mill, and certain application value is arranged.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
