In the figure: 1. a liner plate body; 2. plate peak; 3. bolt holes; 4. a first arcuate segment; 5. a second arcuate segment; 6. a third arc segment; 7. a fourth arc segment; 8. and assembling the clearance.
Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 3, the novel ball mill lining plate provided by this embodiment includes a lining plate body 1, a plate peak 2 is provided on the lining plate body 1, the shape of the plate peak 2 is not limited here, for example, the plate peak 2 may be trapezoidal, or may be circular arc, etc.
The utility model discloses a ball mill, including welt body 1, bolt and ball mill, welt body 1 is equipped with bolt hole 3 in the middle part of the welt body, welt body 1 passes through bolt and ball mill inner wall fixed connection, when using, according to the size of ball mill internal diameter, lays the welt body 1 of different quantity, through material, welt body 1 and ball under the rotation effect of ball mill, realizes polishing to the material, and its specific working process is prior art, does not do not describe here in detail.
In the rotation direction of the ball mill, as shown in fig. 3 and 4 specifically, the counterclockwise is taken as an example for detailed description, the plate peak 2 is located at the front side of the bolt hole 3, the plate peak 2 divides the lining plate body 1 into a lining plate front side section and a lining plate rear side section, the lining plate front side section comprises a first arc section 4 close to the plate peak 2 and a second arc section 5 far away from the plate peak, and the lining plate rear side section comprises a third arc section 6 close to the plate peak and a fourth arc section 7 far away from the plate peak. According to the ball mill rotation direction, through the position that changes 1 upper plate peak 2 of welt body, compensate the congenital deficiency in the product design to the maximize of 1 service function of welt body has been reached, thereby makes 1 wearing and tearing of welt body more balanced, has increased its life.
Further, in order to maximize the use of the lining plate body 1, through a plurality of research tests, specific structural dimensions of the lining plate body 1 may be limited, the distance between the center line of the bolt hole 3 and the center line of the plate peak 2 may be D, the width of the lining plate body 1 is L, 0.1L > D > 0.03L, for example, the width L of the lining plate body 1 is 300mm, the distance between the center line of the bolt hole 3 and the center line of the plate peak 2 may be 9-30 mm, for example, the width L of the lining plate body 1 is 600mm, the distance between the center line of the bolt hole 3 and the center line of the plate peak 2 may be 18-60 mm, and other values may be selected, which is not further illustrated here.
In addition, other structural dimensions may be further defined so as to maximize the use of the liner body 1, and through a combination of a plurality of research experiments, specific examples may include that the radius of the first arc-shaped segment 4 is R1, the radius of the second arc-shaped segment 5 is R2, the radius of the third arc-shaped segment 6 is R3, the radius of the fourth arc-shaped segment 7 is R4, the radius of the R4 is 0.3L, the radius of the R3 is 0.2L, the radius of the R3-D > R1 > R3-1.5D, the radius of the R2 is R4-0.5D, for example, the width L of the liner body 1 is 600mm, D is selected to be 50mm, when the radius of the fourth arc-shaped segment 7 is R4 mm, the radius of the third arc-shaped segment 6 is 120mm, the radius of the second arc-shaped segment 5 is R2 mm, when the radius of the first arc-shaped segment 7 is 180mm, the radius of the first arc-4 mm, and the radius of the liner body is also selected to be 70mm, and are not necessarily described here by way of example.
We find in the installation that when the lower surface of welt body 1 and the inner wall of ball mill were installed, often can be because the unsmooth phenomenon of surface takes place to there is the insecure phenomenon of installation to make easily between welt body 1 and the ball mill, at this moment in order to solve this shortcoming, as preferred, can welt front side section and the bottom of welt rear side section all are equipped with assembly gap 8, through the assembly gap 8 that sets up, can reduce the area of contact between welt body 1 and the ball mill inner wall, thereby make the erection joint of welt body 1 and ball mill inner wall more firm.
Furthermore, in consideration of the cause of wear, the fitting clearance depth of the front section of the lining plate can be C1, the fitting clearance depth of the rear section of the lining plate can be C2, and C1 is 0.5C2, for example, the depth of C1 can be 5-10 mm, at this time, the depth of C2 can be 10-20 mm, specifically, the depth of C1 can be 5mm, and the depth of C2 can be 10mm, but other values can also be adopted.
The present invention is not limited to the above-mentioned examples, and various modifications and changes which can be made by those skilled in the art without creative efforts are protected by the present patent within the scope defined by the claims of the present invention.
