Description
Technical field
The utility model relates to a kind of modified form ladder lining board.
Background technology
Ball mill is applicable to the various ores of grinding and other material, is widely used in ore dressing, the industries such as building materials and chemical industry.Material and abrasive body are housed in the cylindrical shell of ball mill, on barrel, be fixed with liner plate, during barrel body rotation, abrasive body relies on the lifting of liner plate to carry out broken or grinding material, common ladder lining board usually forms " dead angle " phenomenon with adjacent ladder lining board at ladder place, formation backing strap, affects the grinding efficiency of ball mill.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of modified form ladder lining board is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of modified form ladder lining board, be arranged on ball mill barrel inner surface, comprise body, body left side has the arc surface matching with ball mill barrel inner surface, on arc surface, lower end is connected with respectively upper plane and the lower plane extending to arc surface center line, the radial dimension of upper plane and lower plane is identical, body right side has the concaved circular cambered surface that a pair of upper and lower mirror image arranges, two concaved circular cambered surface circular arcs connect, concaved circular cambered surface upper end is above connected with upper plane right-hand member, concaved circular cambered surface lower end is below connected with lower plane right-hand member, two concaved circular cambered surface centers are respectively equipped with the stepped hole that runs through concaved circular cambered surface and arc surface, the upper and lower two ends of described body are thin, middle part is thick.
Described stepped hole comprises the circular hole of arc surface side, elliptical aperture and the transitional pore of concaved circular cambered surface side, and circular hole is communicated with by transitional pore and elliptical aperture.
The beneficial effects of the utility model are: shape of the present utility model is upper and lower symmetry shape, and upper and lower two ends are thin, middle part is thick, thereby except having dribbling function, also eliminated the phenomenon that adjacent ladder lining board forms " dead angle ", solve the problem that produces material pad in mechanical milling process, improved the operating efficiency of ball mill.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
In figure: 1. arc surface; 2. go up plane; 3. lower plane; 4. concaved circular cambered surface; 5. stepped hole.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, a kind of modified form ladder lining board shown in 2, be arranged on ball mill barrel inner surface, comprise body, body has front end face and rear end face, body left side has the arc surface 1 matching with ball mill barrel inner surface, on arc surface 1, lower end is connected with respectively upper plane 2 and the lower plane 3 extending to arc surface 1 center line, upper plane 2 is identical with the radial dimension of lower plane 3, body right side has the concaved circular cambered surface 4 that a pair of upper and lower mirror image arranges, two concaved circular cambered surface 4 circular arcs connect, concaved circular cambered surface 4 upper ends are above connected with upper plane 2 right-hand members, concaved circular cambered surface 4 lower ends are below connected with lower plane 3 right-hand members, two concaved circular cambered surface 4 centers are respectively equipped with the stepped hole 5 that runs through concaved circular cambered surface 4 and arc surface 1, adopt two ball lining board of grinder bolts by stepped hole 5, this modified form ladder lining board can be installed on ball mill barrel inwall respectively, because of these upper and lower two ends of modified form ladder lining board thin, thick middle, therefore just can not form the phenomenon at " dead angle " between adjacent ladder lining board yet.
Described stepped hole 5 comprises the circular hole of arc surface 1 side, elliptical aperture and the transitional pore of concaved circular cambered surface 4 sides, and circular hole is communicated with by transitional pore and elliptical aperture.
Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
Claims (2)
1. a modified form ladder lining board, be arranged on ball mill barrel inner surface, comprise body, it is characterized in that: described body left side has the arc surface matching with ball mill barrel inner surface, on arc surface, lower end is connected with respectively upper plane and the lower plane extending to arc surface center line, the radial dimension of upper plane and lower plane is identical, body right side has the concaved circular cambered surface that a pair of upper and lower mirror image arranges, two concaved circular cambered surface circular arcs connect, concaved circular cambered surface upper end is above connected with upper plane right-hand member, concaved circular cambered surface lower end is below connected with lower plane right-hand member, two concaved circular cambered surface centers are respectively equipped with the stepped hole that runs through concaved circular cambered surface and arc surface, described body middle part is thick, upper and lower two ends are thin.
2. modified form ladder lining board according to claim 1, is characterized in that: described stepped hole comprises the circular hole of arc surface side, elliptical aperture and the transitional pore of concaved circular cambered surface side, and circular hole is communicated with by transitional pore and elliptical aperture.
