Abstract
The invention discloses an improved type stepped lining plate which is mounted on the inner surface of a barrel body of a ball mill. The improved type stepped lining plate comprises a body, wherein the left side of the body is provided with a circular-arc surface which is matched with the inner surface of the barrel body of the ball mill; the upper and the lower ends of the circular-arc surface are connected with an upper plane and a lower plane which extend towards the center line of the circular-arc surface respectively; a pair of concave circular-arc surfaces which are arranged up and down in a mirroring mode is arranged at the right side of the body; the two concave circular-arc surfaces are in circular-arc connection; the upper end of the upper circular-arc surface is connected with the right end of the upper plane; the lower end of the lower circular-arc surface is connected with the right end of the lower plane; stepped holes which penetrate through the concave circular-arc surfaces and the circular-arc surface respectively are formed in the centers of the two circular-arc surfaces respectively; the stepped holes comprise a circular hole in the circular-arc surface side, an oval hole in the concave circular-arc surface side as well as a transition hole, the circular hole is communicated with the oval hole through the transition hole; the body is thin in upper and lower ends, and thick in middle.
Description
Technical field
The present invention relates to a kind of modified form ladder lining board.
Background technology
Ball mill is applicable to the various ore of grinding and other material, is widely used in ore dressing, the industry such as building materials and chemical industry.The cylindrical shell of ball mill is built with material and abrasive body, barrel is 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.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of modified form ladder lining board.
The technical solution adopted for the present invention to solve the technical problems is: a kind of modified form ladder lining board, be arranged on ball mill barrel inner surface, comprise body, there is on the left of body the arc surface matched with ball mill barrel inner surface, on arc surface, lower end is connected to the upper plane and lower plane that extend to arc surface center line, upper plane is identical with the radial dimension of lower plane, there is on the right side of body the concaved circular cambered surface that about a pair mirror image is arranged, two concaved circular cambered surface circular sliding slopes, 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 running 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, the elliptical aperture of concaved circular cambered surface side and transitional pore, and circular hole is communicated with elliptical aperture by transitional pore.
The invention has the beneficial effects as follows: shape of the present invention is upper and lower symmetry shape, and two ends are thin up and down, middle part is thick, thus except there is dribbling function, also eliminate the phenomenon that adjacent steps liner plate forms " dead angle ", solve in mechanical milling process the problem producing material pad, improve the operating efficiency of ball mill.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
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.
Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
One is as shown in Figure 1 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, there is on the left of body the arc surface 1 matched with ball mill barrel inner surface, on arc surface 1, lower end is connected to the upper plane 2 and lower plane 3 that extend to arc surface 1 center line, upper plane 2 is identical with the radial dimension of lower plane 3, there is on the right side of body the concaved circular cambered surface 4 that about a pair mirror image is arranged, two concaved circular cambered surface 4 circular sliding slopes, concaved circular cambered surface 4 upper end is above connected with upper plane 2 right-hand member, concaved circular cambered surface 4 lower end is below connected with lower plane 3 right-hand member, two concaved circular cambered surface 4 centers are respectively equipped with the stepped hole 5 running through concaved circular cambered surface 4 and arc surface 1, adopt two ball lining board of grinder bolts this modified form ladder lining board can be installed on ball mill barrel inwall respectively by stepped hole 5, because these upper and lower two ends of modified form ladder lining board are thin, thick middle, therefore between adjacent steps liner plate, also would not form the phenomenon at " dead angle ".
Described stepped hole 5 comprises the circular hole of arc surface 1 side, the elliptical aperture of concaved circular cambered surface 4 side and transitional pore, and circular hole is communicated with elliptical aperture by transitional pore.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a modified form ladder lining board, be arranged on ball mill barrel inner surface, comprise body, it is characterized in that: there is on the left of described body the arc surface matched with ball mill barrel inner surface, on arc surface, lower end is connected to the upper plane and lower plane that extend to arc surface center line, upper plane is identical with the radial dimension of lower plane, there is on the right side of body the concaved circular cambered surface that about a pair mirror image is arranged, two concaved circular cambered surface circular sliding slopes, 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 running through concaved circular cambered surface and arc surface, thick in the middle part of described body, upper and lower two ends are thin.
