Abstract
A kind of nonabradable end cover of ball mill frid, belongs to ball mill equipment technical field, for reducing the wearing and tearing of end cover of ball mill frid.Its technical scheme is: the opposite flank on the surface that frid is relative with end cover of ball mill and between adjacent frid is processed with groove, magnet is inlaid with in groove, the magnetic absorption magnetic mineral of magnet forms dividing strip, dividing strip is neither easy to wear, again because the effect of magnet magnetic absorption is constantly supplemented, and adaptive height can be formed along with gap size, this fills up the gap between frid and end cover of ball mill highly just, reach the object of the ore pulp flowing hindered between gap, thus alleviate or prevent the wearing and tearing that therefore occur.The utility model structure is simple, can alleviate or prevent the wearing and tearing that the ore pulp flowing into gap between end cover of ball mill and frid causes end cover of ball mill and frid matching surface, extend the service life of frid, greatly reduce maintenance work and maintenance cost, reduce production cost.
Description
Technical field
The utility model relates to a kind of frid be fixed on end cover of ball mill, belongs to ball mill equipment technical field.
Background technology
At present, the frid on end cover of ball mill is non magnetic frid, and non magnetic frid is secured by bolts on end cover of ball mill, for preventing end cover of ball mill from directly being worn and torn by ore, and plays the effect connecting grate.But certain gap can be had between end cover of ball mill and fixing frid, by end cover of ball mill and frid driven rotary in ore pulp inflow gap, end cover of ball mill and frid can be caused to produce the heavy wear of annular at the matching surface close to region, the center of circle.The non magnetic frid of general end cover of ball mill is without the function alleviating or prevent this wearing and tearing, the serious wear of frid and end cover of ball mill matching surface constrains the service life of frid under normal circumstances, frid is caused to scrap in advance, add maintenance work and maintenance cost, improve production cost, be extremely necessary to be improved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of nonabradable end cover of ball mill frid, this frid can promote the sealing property between frid and end cover of ball mill, significantly reduce the rate of wear of frid and end cover of ball mill matching surface, extend the service life of frid.
The technical scheme solved the problems of the technologies described above is:
A kind of nonabradable end cover of ball mill frid, it is fan-shaped frid, frid there is fixing threaded hole, frid is fixed on end cover of ball mill by fixing threaded hole by bolt, and the overall frid of polylith fan-shaped frid composition end cover of ball mill, the frid plate face that frid is relative with end cover of ball mill is processed with many grooves, many grooves are respectively along the radius of a circle in fan-shaped frid plate face, be embedded with magnet in a groove, magnet sidewall and groove for closely cooperating, the upper surface of magnet and frid planes align.
Above-mentioned nonabradable end cover of ball mill frid, fluted on the connection side of the fan-shaped frid of described polylith, groove is positioned on the center line of frid side, is embedded with magnet in a groove, magnet sidewall and groove are for closely cooperating, and the upper surface of magnet flushes with frid side.
The beneficial effects of the utility model are:
Opposite flank on the surface that frid is relative with end cover of ball mill and between adjacent frid is processed with groove to the utility model, magnet is inlaid with in groove, the magnetic absorption magnetic mineral of magnet forms dividing strip, the dividing strip that this iron powder is formed is neither easy to wear, again because the effect of magnet magnetic absorption is constantly supplemented, and adaptive height can be formed along with gap size, this fills up the gap between frid and end cover of ball mill highly just, reach the object of the ore pulp flowing hindered between gap, thus alleviate or prevent the wearing and tearing that therefore occur.The utility model structure is simple, can alleviate or prevent the wearing and tearing that the ore pulp flowing into gap between end cover of ball mill and frid causes end cover of ball mill and frid matching surface, extend the service life of frid, greatly reduce maintenance work and maintenance cost, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure, mark is as follows: frid 1, groove 2, magnet 3, fixing threaded hole 4.
Detailed description of the invention
The overall frid of end cover of ball mill is made up of the fan-shaped frid of polylith, and every block frid 1 has fixing threaded hole 4, and frid 1 is fixed on end cover of ball mill by fixing threaded hole 4 by bolt.
Show in figure, frid 1 of the present utility model is processed with many grooves 2 on the frid 1 plate face that frid 1 is relative with end cover of ball mill, many grooves 2 are respectively along the radius of a circle in fan-shaped frid 1 plate face, magnet 3 is embedded with in groove 2, magnet 3 sidewall and groove 2 for closely cooperating, the upper surface of magnet 3 and frid 1 planes align.The effect of groove 2 and magnet 3 is: the magnetic absorption iron powder of magnet 3 forms dividing strip, the dividing strip that this iron powder is formed is neither easy to wear, again because the effect of magnet magnetic absorption is constantly supplemented, and adaptive height can be formed along with gap size, this fills up the gap between frid 1 and end cover of ball mill highly just, reach the object of the ore pulp flowing hindered between gap, thus alleviate or prevent the wearing and tearing that therefore occur.
Show in figure, on the frid 1 connection side with adjacent frid 1 also fluted 2, groove 2 is positioned on the center line of frid 1 side, is embedded with magnet 3 in groove 2, and magnet 3 sidewall and groove 2 are for closely cooperating, and the upper surface of magnet 3 flushes with frid 1 side.The groove 2 of frid 1 side and magnet 3 play a part to reduce wearing and tearing between adjacent frid 1 equally.
