Description

Technical Field

[0001] The utility model relates to the technical field of classification devices, in particular to a ball classification device for a ball mill. Background Art

[0002] Ball mill is the key equipment for crushing materials after they are broken. This type of grinding mill is a mill with a certain number of steel balls as grinding media in its cylinder. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries. It can grind various ores and other grindable materials by dry or wet method. Ball mill is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical industries.

[0003] When grinding materials, existing ball mills use the falling steel balls and their own gravity to impact the materials through rotation, thereby crushing the materials. Ball mills of different specifications need to be equipped with steel balls of different specifications.

[0004] The existing classification and screening of steel balls generally adopts the method of manual quality inspection and then removing them manually. This method consumes a lot of manpower during the operation of the assembly line and does not conform to the development trend of intelligent assembly lines. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a ball mill ball classification device, which overcomes the shortcomings of the prior art and effectively solves the problem that the prior art uses manual removal, which consumes a lot of manpower during the operation of the assembly line and does not conform to the development trend of intelligent assembly lines.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A ball mill ball classification device comprises a fixed frame, a truncated table is arranged in the fixed frame, and the top of the truncated table is rotatably connected to a rotating column, the top of the rotating column is connected to a rotating mechanism, and the rotating mechanism comprises a turntable, a connecting plate fixed to the annular outer wall of the turntable at equal distances, a connecting rod fixed to one end of the bottom of the connecting plate, a baffle fixed to the bottom of the connecting rod, a U-shaped block clamped to the bottom of the connecting plate, a fixed rod fixed to the bottom of the U-shaped block, a connecting shell fixed to the bottom of the fixing rod, and a rolling ball rotatably connected to the connecting shell.

[0008] The balls of different specifications are continuously conveyed to the top of the placement plate in the fixed frame through an external conveyor belt. The output shaft of the servo motor drives the rotating column to rotate through mutually meshing gears. The rotating column drives the rotating mechanism to rotate continuously. The baffle rotating around the frustum continuously pushes the balls on the placement plate, so that the balls of different specifications fall from different meshes when passing through the sieves with different mesh sizes, thereby achieving the purpose of classifying and screening the balls.

[0009] Preferably, fixing plates distributed at equal distances are fixed to the bottom of the annular outer wall of the truncated cone, and one end of the fixing plate away from the truncated cone is connected and fixed to the inner wall of the fixing frame.

[0010] The round table is connected and fixed with the fixing frame through a fixing plate.

[0011] Preferably, the annular outer wall of the cone is connected with a placement plate and equidistantly distributed screens, and the mesh sizes of the screens increase successively.

[0012] The spheres first fall onto a placement plate, and then are sorted and screened by sieves with different mesh sizes.

[0013] Preferably, a servo motor is installed on the top of the truncated table, and the output shaft of the servo motor and the outer wall of the rotating column are both sleeved and fixed with mutually meshing gears.

[0014] The output shaft of the servo motor drives the rotating column to rotate through mutually meshing gears.

[0015] Preferably, the bottom of the baffle forms a sliding fit with the screen and the placement plate, and the outer walls at both ends of the baffle form a sliding fit with the outer wall of the truncated table and the inner wall of the fixed frame respectively.

[0016] When the baffle rotates around the frustum, the balls on the plate are pushed, so that the balls are screened through the screen in turn.

[0017] Preferably, an annular slide groove is provided on the top of the truncated table, and the annular slide groove and the rolling ball form a rolling fit.

[0018] The rolling ball rolls along the annular groove, thereby supporting and stabilizing the rotation of the rotating mechanism.

[0019] The beneficial effects of the utility model are:

[0020] Spheres of different sizes are continuously conveyed to the top of the placement plate in the fixed frame through an external conveyor belt, and the servo motor drives the rotating mechanism to rotate continuously through the rotating column. The baffle rotating around the frustum continuously pushes the spheres on the placement plate, so that spheres of different sizes fall from different meshes when passing through sieves with different mesh sizes, thereby achieving the purpose of classifying and screening the spheres, effectively solving the problem of manual removal in the prior art, which consumes more manpower during the operation of the assembly line and does not conform to the development trend of intelligent assembly lines.
