Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a grate lining plate for a mill. Background Art

[0002] Ball mill liner is an important component of the ball mill, mainly used to protect the cylinder from direct impact and friction between the grinding body and the material. The material of ball mill liner is various, including high manganese steel, medium alloy steel, low chromium alloy cast steel, high chromium alloy cast steel and rubber. The grid liner refers to the grid-shaped liner at the discharge end, which is mainly used in ball mills in the mining industry.

[0003] During the use of the grate lining, the grate lining will be repeatedly impacted by the mineral material. Under long-term impact, some parts of the grate lining will inevitably bend, deform, and be damaged. Some grate liners currently on the market are circular integral structures. When damage occurs, the entire lining needs to be replaced, which not only causes waste but also increases production costs. In view of this, we propose a mill grate lining. Utility Model Content

There are installation cavities 14 in between; a plate body 16 is inserted in the installation cavity 14, and a plurality of through slots 162 are opened on the plate body 16. Limit strips 160 are fixed to the outer walls on both sides of the plate body 16, and the limit strips 160 are plugged into and matched with the corresponding limit slots 130; an insert block 18 is installed at one end of the plate body 16, and the insert block 18 is plugged into and matched with the corresponding slot 151, and a connecting plate 17 is fixed at the other end of the plate body 16, and the connecting plate 17 passes through the connecting groove 10, and a connecting hole 170 is opened on the connecting plate 17, the threaded column 11 passes through the connecting hole 170, and the nut 12 is pressed against the connecting plate 17.

[0027] In this embodiment, the cross-section of the connecting groove 10 is arc-shaped, and the size of the connecting groove 10 is adapted to the size of the connecting plate 17. This design facilitates stable cooperation between the connecting plate 17 and the connecting groove 10, ensuring the installation stability of the plate body 16.

[0028] In this embodiment, the upper and lower end surfaces of the plate body 16 are each provided with a plurality of cavities 161, and the through slots 162 are located in the cavities 161. The provision of the cavities 161 not only saves materials used in the production of the plate body 16, but also improves the structural strength and service life of the plate body 16.

[0029] In this embodiment, the end of the plate 16 close to the inner ring 15 is arc-shaped, and the end of the plate 16 is in contact with the outer wall of the inner ring 15. This design facilitates the end of the plate 16 to fit in contact with the outer wall of the inner ring 15, thereby ensuring the installation stability of the plate 16.

[0030] In this embodiment, the plate body 16, the limiting strip 160, the insert 18, and the connecting plate 17 are integrally formed, and the cross-section of the plate body 16 is fan-shaped. This integral structure provides greater structural strength, ensures the stability of the connection between the plate body 16, the limiting strip 160, the insert 18, and the connecting plate 17, and guarantees the service life of the plate body 16.

The tight welding method ensures the installation reliability of the partition 13 and ensures the service life of the liner.

[0033] It should be added that the threaded column 11 in this embodiment is tightly welded to the inner wall of the connecting groove 10. The tight welding method ensures the connection reliability and stability between the threaded column 11 and the outer ring body 1, thereby making the threaded column 11 have a better fixing effect on the plate body 16, ensuring the installation reliability of the plate body 16.

[0034] When the plate body 16 needs to be removed for replacement, the user first rotates the nut 12, and the nut 12 disengages from the threaded column 11, and the restriction of the nut 12 on the connecting plate 17 is released. Then the user pulls the plate body 16 to one side, and the limit bar 160 slides along the limit groove 130, and the insert block 18 disengages from the slot 151. When the plate body 16 is out of the installation cavity 14, the plate body 16 is removed.

[0035] The above shows and describes the basic principles, main features, and advantages of the present invention.
