In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a high-efficient stable ball mill, includes the barrel that the level was placed, is located the hollow shaft at barrel both ends and is used for supporting the bearing frame of hollow shaft, the outside lower part clearance fit of barrel has the cross section to be the curved cover body, the inboard of the cover body is equipped with the permanent magnet of arc structure.

Furthermore, a placing plate is arranged between the bottoms of the bearing seats, and a supporting seat is arranged on the top surface of the placing plate.

Furthermore, the supporting seat is located in the middle of the bottom surface of the cover body, and the top of the supporting seat is fixedly connected with the bottom surface of the cover body.

Furthermore, the cover wall of the cover body close to the cylinder body is made of magnetic conducting materials, and the cover wall of the cover body far away from the cylinder body is made of magnetic shielding materials.

Furthermore, the permanent magnet is formed by splicing a plurality of permanent magnet blocks with arc structures, and the permanent magnet blocks are arranged in a rectangular array.

Further, a plurality of lining plates are uniformly arranged on the inner wall of the barrel body, and the length directions of the lining plates are consistent with the length direction of the barrel body.

Compared with the prior art, the utility model has the beneficial effects that:

according to the grinding device, the permanent magnet on the outer side of the cylinder body has a certain adsorption force on the grinding body in the cylinder body, when the grinding body on the inner side of the cylinder body is positioned at the bottom of the inner side of the cylinder body, the grinding body can stably ascend along with the rotation of the cylinder body under the action of the permanent magnet, when the ascending position exceeds the range of the action of the permanent magnet, the grinding body is thrown out under the action of gravity, along with the fact that materials on the inner side of the cylinder body are closer, the acting force of the permanent magnet is larger, the crushing effect of the grinding body on the materials is increased, even if the grinding body is buried in the materials, the grinding body can stably move to a high position along with the cylinder body under the action of the permanent magnet, and therefore the continuous and stable grinding efficiency is guaranteed.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions:

the utility model provides a high-efficient stable ball mill, includes the barrel 1 that the level was placed, is located the hollow shaft 2 at barrel 1 both ends and is used for supporting hollow shaft 2's bearing frame 3, and the clearance fit has the cross section to be curved cover body 4 in the outside lower part of barrel 1, and the inboard of cover body 4 is equipped with the permanent magnet 5 of arc structure.

Permanent magnet 5 in the barrel 1 outside has certain adsorption affinity to the rinding body of barrel 1 inside, when the inboard rinding body of barrel 1 is located barrel 1 inboard bottom, receive the effect of permanent magnet 5, make the rinding body can be stable rise along with the rotation of barrel 1, when the position that rises surpasss the scope that permanent magnet 5 can act on, the rinding body throws out under the action of gravity, along with also being close to the inboard material of barrel 1 more, the effort that receives permanent magnet 5 is just bigger, thereby increase the effect of smashing of rinding body to the material, even if bury inside the material, the rinding body also can be stable under the effect that receives permanent magnet 5 and remove to the high-order along with barrel 1, thereby guarantee the continuation and stability of grinding efficiency.

Be equipped with between the bottom of bearing frame 3 and place board 6, the top surface of placing board 6 is equipped with supporting seat 7, places board 6 and guarantees that bearing frame 3 places stably the time, can also realize the outrigger to supporting seat 7.

The supporting seat 7 is located the bottom surface middle part of the cover body 4, and the top of the supporting seat 7 is fixedly connected with the bottom surface of the cover body 4, and is located at the middle position of the cover body 4, so that the supporting performance of the supporting seat 7 is better, and the fixed connection can also avoid the occurrence of relative position movement of the cover body 4 and the supporting seat 7.

The cover wall that the cover body 4 is close to barrel 1 one side is magnetic material, and the cover wall that the cover body 4 is far away from barrel 1 one side is magnetic screen material, and magnetic material does not influence the adsorption of permanent magnet 5 to the inside rinding body of barrel 1, and magnetic screen material can reduce the influence of permanent magnet 5 to the cover body 4 outside object.

The permanent magnet 5 is formed by splicing a plurality of permanent magnets with arc structures, the permanent magnets are arranged in a rectangular array, the manufacturing and maintenance difficulty of the permanent magnet 5 is reduced, and the manufacturing and use cost is reduced.

Evenly be equipped with a plurality of welts 8 on the inner wall of barrel 1, the length direction of welt 8 is unanimous with the length direction of barrel 1, and welt 8 rotates the in-process at barrel 1 and can effectively promote by absorbent rinding body and remove to high level, guarantees that the stability of grinding goes on.
