Abstract
The invention discloses an improved stepped liner plate which is mounted on the inner surface of a barrel body of a ball mill. The improved stepped liner plate comprises a liner plate body; the front end and the rear end of the liner plate are planes which are parallel to each other; an arc-shaped surface in match with the inner surface of the barrel body of the ball mill is arranged at the left side of the liner plate body; an upper plane and a lower plane which extend to a rotating center of the arc-shaped surface are connected to the upper end and the lower end of the arc-shaped surface; the radial size of the upper plane is more than that of the lower plane; a first inclined surface which is inclined toward the lower right side is connected to the free end of the upper plane; a second inclined surface which is inclined toward the upper right side is connected to the free end of the lower plane; a concave arc-shaped surface for lifting a mill body is arranged at the right side of the liner plate body; the upper end of the concave arc-shaped surface is in arc-shaped connection with the first inclined surface while the lower end of the concave arc-shaped surface is in arc-shaped connection with the second inclined surface; the distance from the upper end of the concave arc-shaped surface to the arc-shaped surface is more than the distance from the lower end of the concave arc-shaped surface to the arc-shaped surface; a rectangular cavity is formed in the arc-shaped surface; a boss is arranged in the rectangular cavity; stepped through holes which pass through the boss and the concave arc-shaped surface are formed in the center of the boss.
Description
Technical field
The present invention relates to a kind of ladder lining board of improvement.
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, 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 at ladder place, and formation backing strap affects the grainding capacity 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 ladder lining board of improvement.
The technical solution adopted for the present invention to solve the technical problems is: 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 be parallel to each other, 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 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 tilted to lower right side, the free end of lower plane is connected with the second inclined-plane tilted to upper right side, there is on the right side of described body the concaved circular cambered surface for promoting abrasive body, concaved circular cambered surface upper end and the first inclined-plane circular sliding slopes, concaved circular cambered surface lower end and the second inclined-plane circular sliding slopes, concaved circular cambered surface upper end is greater than the distance of concaved circular cambered surface lower end to arc surface to the distance of arc surface, described arc surface is provided with rectangle cavity, boss is provided with in rectangle cavity, boss center is provided with the step through-hole running through boss and concaved circular cambered surface.
Described step through-hole comprises the circular hole of boss side, the elliptical aperture of concaved circular cambered surface side and transitional pore, and circular hole is communicated with elliptical aperture by transitional pore.
Described arc surface offers two longitudinal flutings and a transverse concave groove.
The invention has the beneficial effects as follows: lower end of the present invention adds the second inclined-plane promoting abrasive body, the problem of grinding " dead angle " is resolved, thus improve 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.
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. 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
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.
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 be parallel to each other, there is on the left of described 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 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 tilted to lower right side, the free end of lower plane 3 is connected with the second inclined-plane 5 tilted to upper right side, there is on the right side of described body the concaved circular cambered surface 6 for promoting abrasive body, concaved circular cambered surface 6 upper end and the first inclined-plane 4 circular sliding slopes, concaved circular cambered surface 6 lower end and the second inclined-plane 5 circular sliding slopes, concaved circular cambered surface 6 upper end is greater than the distance of concaved circular cambered surface 6 lower end to arc surface 1 to the distance of arc surface 1, described arc surface 1 is provided with rectangle cavity 7, boss 8 is provided with in rectangle cavity 7, boss 8 center is provided with the step through-hole 9 running through boss 8 and concaved circular cambered surface 6, ball grinding machine lining board bolt is used namely to be installed on ball mill barrel inwall by this ladder lining board by this step through-hole 9.
Described step through-hole 9 comprises the circular hole of boss 8 side, the elliptical aperture of concaved circular cambered surface 6 side and transitional pore, and circular hole is communicated with elliptical aperture by transitional pore.
