Description
Technical field
The utility model relates to a kind of ladder lining board of improvement.
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, are fixed with liner plate, when 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 at ladder place, formation backing strap affects the grainding capacity 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 ladder lining board of improvement is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of ladder lining board of improvement, be arranged on ball mill barrel inner surface, comprise body, before body, rear end is the plane being parallel to each other, described body left side has the arc surface matching with ball mill barrel inner surface, on arc surface, lower end is connected with respectively the upper plane and the lower plane that extend to the arc surface centre of gyration, the radial dimension of upper plane is greater than the radial dimension of lower plane, the free end of upper plane is connected with the first inclined-plane tilting to lower right side, the free end of lower plane is connected with the second inclined-plane tilting to upper right side, described body right side has the concaved circular cambered surface for promoting abrasive body, concaved circular cambered surface upper end is connected with the first inclined-plane circular arc, concaved circular cambered surface lower end is connected with the second inclined-plane circular arc, concaved circular cambered surface upper end to the distance of arc surface is greater than the distance of concaved circular cambered surface lower end to arc surface, described arc surface is provided with rectangle cavity, in rectangle cavity, be provided with boss, boss center is provided with the step through-hole that runs through boss and concaved circular cambered surface.
Described step through-hole comprises the circular hole of boss 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.
On described arc surface, offer two longitudinal flutings and a transverse concave groove.
The beneficial effects of the utility model are: the utility model lower end has increased the second inclined-plane that promotes abrasive body, the problem of grinding " dead angle " is resolved, thereby improved the grainding capacity of ball mill, the second inclined-plane is obviously greater than the hoisting power of concaved circular cambered surface to abrasive body to the hoisting power of abrasive body.
Brief description of the drawings
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. the first inclined-plane; 5. the second inclined-plane; 6. concaved circular cambered surface; 7. rectangle cavity; 8. boss; 9. step through-hole; 10. longitudinal fluting; 11. transverse concave grooves.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Fig. 1, the ladder lining board of a kind of improvement shown in 2, be arranged on ball mill barrel inner surface, comprise body, before body, rear end is the plane being parallel to each other, described 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 the upper plane 2 and the lower plane 3 that extend to arc surface 1 centre of gyration, the radial dimension of upper plane 2 is greater than the radial dimension of lower plane 3, the free end of upper plane 2 is connected with the first inclined-plane 4 tilting to lower right side, the free end of lower plane 3 is connected with the second inclined-plane 5 tilting to upper right side, described body right side has the concaved circular cambered surface 6 for promoting abrasive body, concaved circular cambered surface 6 upper ends are connected with the first inclined-plane 4 circular arcs, concaved circular cambered surface 6 lower ends are connected with the second inclined-plane 5 circular arcs, concaved circular cambered surface 6 upper ends to the distance of arc surface 1 is greater than the distance of concaved circular cambered surface 6 lower ends to arc surface 1, described arc surface 1 is provided with rectangle cavity 7, in rectangle cavity 7, be provided with boss 8, boss 8 centers are provided with the step through-hole 9 that runs through boss 8 and concaved circular cambered surface 6, use ball grinding machine lining board bolt this ladder lining board to be installed on ball mill barrel inwall by this step through-hole 9.
Described step through-hole 9 comprises the circular hole of boss 8 sides, elliptical aperture and the transitional pore of concaved circular cambered surface 6 sides, and circular hole is communicated with by transitional pore and elliptical aperture.
During for ease of installation ladder lining board, extrude the cement mortar in rectangle cavity 7, on described arc surface 1, offer two longitudinal flutings 10 and a transverse concave groove 11.
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.
